Nexus Root Toolkit v1.9.1

Unlocking, rooting, relocking and unrooting simplified! (and much more!)

VERSION 1.9.1  - This program will automatically bring together all the files you need to unlock and root your device in a few clicks, or flash it back to stock and re-lock it. You can also use this program to backup/restore all your important data, flash zips, set file permissions, push and pull files, install apps, generate logcats/bugreports, and much more! With the included file association options, you can perform tasks like flashing zips, installing apps, restoring android backup files, and flashing/booting img files with just a double click! The program includes a full featured interface for automating tasks in TWRP, enhanced restore features, an in-built auto-updater/notification system, ‘any build’ mode, advanced restore features,’NRT- Live Log’ for viewing the adb/fastboot cmds that are run in the background, quick tools utilities, and tools for taking screenshots/screen-recordings.   All the latest official Android builds and Nexus devices are supported.  The program intelligently and selectively downloads the files it needs for your device and makes sure you are using the latest files available.  The program can even auto-detect your device and build.  This release brings major changes, including a redesigned hybrid downloader, double check automatic device-detection, live-log toggle, and codebase upgrades for future work.  Check out the updated changelog for a more comprehensive breakdown of the feature set and changes in this release.

    Its a false positive, please report it to your AV provider so they can review it, deem it safe and whitelist it.

    The programming language this is written in (Autoit) is known to get falsely flagged. The reason it’s getting flagged now is probably because I updated it and McAfee has yet to whitelist it.

    I am the sole developer and publisher of this application and if you downloaded it from my website and the hash value matches what I posted there then I guarantee its 100% clean and will always be.

    I use to report it to AV providers myself but it is too time consuming, so I ask that users please report it themselves.

  • Ricardo Serrano

    I’m running Android L on a Nexus 5 and I want to root it. Is it possible?

    • Milancius

      It is possible, you just need to reboot into custom recovery via temporary boot. Trust me, it works :) And you need the latest SuperSU and boot fix, just google it :)

      • Jose Roca

        Great! Thanks I’m testing now (fingers crossed)

  • Sebastian Brochocki

    when NRT upgrade to android L install?

  • Penis

    No, you can go straight to 4.4.4.

  • Penis

    See if either Media drive (MTP) or Camera (PTP) is checked under Settings -> Storage -> USB computer connection.

  • Eric Strom

    Google Chrome is also flagging it as malicious.

    • http://wugfresh.com/ WugFresh

      Yeah, its a false positive. Not sure how to report it to them.

  • M.F. Lawrey

    HI Wugfresh, let me say great work with NRT. I will say tho, i trashed my first N7 v2 2013 wifi tablet the first round after 4.4.3 OTA. prolly my ignorance. Now 2nd round new N7 v2. updated 4.4.3. unlocked and rooted, flawless. Now next OTA is out, not wanting to do trash another, dint accept OTA yet, Trying to “flash+unroot” keep getting same “no system, boot,recovery,img” It appears to me NRT isnt reading the the files inside the included zip file. Only seen one other post about this problem, and answer was corrupt,incomplete download. I have used NRT to d/l both the 4.4.3 and 4.4.4 file multiple (9-10) times and d/led direct from google, all say matched and complete. Never used and not opposed to using ADB method just alittle gun shy ATM. Thanks and sorry for being long winded

    • http://wugfresh.com/ WugFresh

      Can you provide a screenshot.

      • M.F. Lawrey

        yes sir, sorry for both monitors

        • http://wugfresh.com/ WugFresh

          I will investigate the issue. I really don’t see why that would happen. Can you msg me in google chat.

          • M.F. Lawrey

            message sent thanks

          • M.F. Lawrey

            AS an update. I pulled out old back-up comp. w7 pro 32bit. long story short, i got NRT installed and set -up, d/l image direct from google, ran the “flash stock+unroot” ran flawless. so, maybe a 64bit issue? anyway hope that helps figure out what went wrong. Thanks Wugfresh great job. small thanks sent from paypal =)

          • Xylometazol .

            I’ve kept getting same errors both times when updating to 4.4.3 and now 4.4.4(for img from google and NRT) without wiping user data. Force flash mode worked well

    • lol hai

      you IDIOT have you considered the option that NRT is corrupt.

  • Justin Deain

    hey i need help i unrooted and flashed the stock rom on my nexus 4 and it said it is finished and its booting up now and its booting now for 2 hours and its still booting at the color changing screen

  • Nexus 5. 16 GB. 4.4.4.4 kk

    thanks guys for everything you do I just had a quick question I want to know if there’s a way you can take T Mobile throttle iand just totally just get rid of it is there a way to do that and thanks for everything….!!!!

  • fingrlakes

    Is there a way to flash my nexus without turning on debugging?

  • BDPSU

    After upgrading to Android 4.4.4, NRT will not re-root my unlocked Nexus 4. It boots the phone into the bootloader, but then the phone sits on “downloading”, and NRT says that it’s “Booting modified boot.img to enable privileged commands”. It never moves beyond that point.

    I’ve tried running this several times and letting it run for 10 minutes or more – it never works.

    Any idea what the problem is?

    Thanks.

  • GigaCode

    Are you going to add “L” support anytime soon ?

    • http://wugfresh.com/ WugFresh

      Full L support will be added when the official release comes out. The toolkit can flash and root it, but no full automation of other procedures yet.

  • Maku Suchinben

    Sir WugFresh, I encountered M.F. Lawreys problem, but in my case im using 32bit w7, and i already have downloaded the ktu84l factory file.. NRT cant find system.img… Help me please

  • BA14

    complete noob to this but seeing the same: both downloads proposed on starting NRT fail having shown 1% downloaded and then a hash-check fail. Using NortonIS – no pop ups or log entries to suggest that’s the problem. If downloading manually is the answer could someone please send me a link and a clue where to put the files ! Thanks

  • Peter Gutierrez

    WugFresh. first of all thank you for the toolkit. it gave me a bit of trouble(because of my dumbness), but overall, smooth. Here is a solution I found: I am using windows 7/64 and was rooting a nexus 4(4.4.4). there are two files that were not pulling automatically 1.modified_boot_occam_4.4.4_KTU84P.img and 2.openrecovery-twrp-2.7.1.0-mako.img. since it is not doing so, when attempting to root with or without custom img., you hang mid process. what I did was pull them manually(as instructed by your toolkit), had nrt browse locally after download, then merged them. once that was done, I reattempted, and pow!!! im in. I don’t know if this issue was resolved already, but I hope I could help someone who needs it. Thank you again!!!!

  • Michael Kramer

    Following is what I have been after a day of trying to fix my boot-looped nexus 7 (2012) any ideas?

  • Wayne Rumble

    My nexus 7 running 4.4.4 has been backed up and unlocked succesfully but fails during the rooting procedure because the nexus keeps stalling when it says booting downloaded img. Any ideas on how to help?

    • Austen Evans

      I have exactly same N7 and issue, hopeful for resolution soon :)

      • http://wugfresh.com/ WugFresh

        Make sure you select the correct N7, or use auto-detect. There are four options.

  • Austen Evans

    Hi..
    Awesome work, long time supporter / donater (since you fixed my bricked N7 :) )
    Have upgraded my WiFi+Cell Nexus 7 to 4.4.4 and can no longer root.
    Upgrading didn’t “re-lock” the device of tamper with the ADB drivers, all that continues to work fine.
    Toolkit seems to think that it’s pushing the Root files OK and boots into Bootloader but it just sits there.
    After Toolkit times out selecting “Recovery Mode” on the N7 gives me the Android Dude with an ” ! “.
    I have tried with both TWRP and CWM to no avail.
    Haven’t had this issue before, previous Roots have been “as advertised” !!
    Thanks.

    • http://wugfresh.com/ WugFresh

      sorry for really late response. Did you ever resolve this? Make sure you select the right Neuxs7 device in the toolkit.

  • http://about.me/d.bennett Dan Bennett

    The auto-updater downloads 1% and then says complete but obviously fails the hash check, so I came here to download directly. However, no matter which of the three download links I try I get a 72.3MB file instead of 72.2MB and the MD5 never matches. Any idea what’s going on?

    I would be fine without upgrading seeing as I’m still using a Nexus 4 which 1.7.9 handles just fine, except that there’s apparently an update to CWMR which 1.7.9 refuses to download or recognise if I download manually – and it won’t let me do a NANDroid without first updating CWMR. Very frustrating.

    • http://about.me/d.bennett Dan Bennett

      Never mind, tried again this evening and it installed fine after my first download attempt. Now I can get around to backing up my phone so I can update CyanogenMod!

  • Giorgi Bregvadze

      Make sure you have selected the correct device and build in the toolkit. Make use of the “Auto-detect” if you are not sure. If an android device ever freezes on you, just force powerdown with the power button.

      Read the instructions above or watch one of the youtube videos. Unlock is required to root. Unlocking wipes, so backup first.

    Direct linking does NOT work on AndroidFileHost. It’s advised by them not to, so CDN can determine the best mirror location to serve the file.

    • http://wugfresh.com/ WugFresh

      I just checked and its not working. That is strange. Thank you for bringing this to my attention. That said, it has worked on this page in the past. AndroidFileHost gave me a developer API key specifically for this reason – so I could deliver direct downloads. That’s how all the files are served through the toolkit.

      • Suagat

    Wugfresh. Thanks for developing your toolkit. I’ve been using it for a year – I have a nexus 7 2013.

    For 2 weeks I have many problems with twrp backups not restoring and boot loop. Im not sure what is going wrong as it is usually works fine. Its not an issue with your toolkit but I hoped you could help.

    I have kk 444 stock not rooted as primary ROM

    I have android l not rooted as secondary

    When I switch between these ROM using twrp backup/restore it gets stuck during boot at the coloured circles stage. The only fix is to flash stock and start over.

    Any advice?

  • gladvold

    Hi! I have previously successfully unlocked and rooted my Nexus4 with your toolkit. Kept stock, no custom ROM. Since then I have received Google OTA system updates, and because of that the phone is no longer rooted. But is it still unlocked, can I skip unlocking this time? Will I loose app data etc. if I root again?

  • Luqman NH

    Nexus 4 user here! I love this toolkit. Making flashing ROMs and stuff more easy without having to use adb whatever command ;D
    Though sometimes there is this problem where I want to restore backup that I made using this toolkit and it doesn’t seem to work. I’d be glad if you fix this :)

    Donated ;)
    You deserve it.
    And keep the project going!

    • http://wugfresh.com/ WugFresh

  • zdenek faltus

    Hello, for the first time here .. First of all, let me to thank you for this wonderful guide and programme ! I got a bit angry with Google for storing all my photos somewhere in the cloud and started to look up the info abvout rooting my Nexus 5. I got a bit angry with the feeble ringing as well.
    Today I have performed my first root with the help of your programme – everything went on smoothly, but after the rooting I had no camera app ! So, I had to flash back the stock ROM and I do hope that the cam will be back:
    So, in the meantime the flash went Ok, the camera is back … What could be the problem ? An secondly,
    what king of custom ROM could I flash after the eventual new rooting?
    Thanks a lot for a possible input and thank you once more !

      Are you running 1.8.6? What options did you have selected when rooting your Nexus? Flash recovery? Busybox free? When exactly does this message show up? Do you see the rooting complete message? Is your device rooted.

      • Freewer39

        Yes, I’m running the 1.8.6 version.

        I choose TWRP Recovery when I’m rooting my phone.

        I don’t know when exactly he his showing up and the rooting complete message didn’t appear but I solved the problem by checking the “Busy Box Free” installation (I unchecked it before) and my device is now roote :)

        Thanks

  • Michael

    used it to unlock nexus7 and install Android L.

    Worked great!

  • AJ1993

    Hi! I am still stuck up with this error while installing. Can you help?
    Windows cannot find ‘NexusRootToolkit.exe’. Make sure you typed the name correctly, and then try again.

    • YoGiFiEd

      Create a new folder on c: and copy the install file to that folder and right-click the install file and “run as admininstrator”. Also real-time security/av software can temp block exe files during an installation.

      Also if youre getting mismatch errors on the updates just manually add the program exe as an exception to your firewall.

      • AJ1993

        clearly the issue was with my antivirus program blocking the installation. Thanks for the help mate!

        • http://wugfresh.com/ WugFresh

          Can you tell me which antivirus you use so I can report it to them.

  • Leonardo Floresta Nascimento

    firstly congratulations on application
    already used it to root and everything went well
    today after almost two months, but today the touch became unresponsive.
    Restarted, and so now he caught the screen with the Google logo.
    He goes into fastboot, but does not go into recovey mode … used your app in “back to stock” and then the second application all went well … but after all process is finished, it remains on the screen with the google logo.

    sorry for bad english.

    • http://wugfresh.com/ WugFresh

      Are you sure the flash stock completes? How long was the process? You may need to perform a manual factory reset. Check out the instructions under ‘Reset Device in Recovery Mode’ – https://support.google.com/nexus/answer/4596836

      • Leonardo Floresta Nascimento

        lasted about 2 minutes … I will add a print to see you …
        the tablet I can not get into recovery, because when I select “recovery mode” in the “fastboot” and press power button, the tablet restarts but returns to the screen from google.
        I’ve tried with 4.4.3 and 4.4.4 and still not getting into the android.
        I’m already more than seven hours in this sad joke … xD
        The strangest thing was that this afternoon after more than three hours attempted, he entered the android, but remained unresponsive to touch … so I rebooted again … and so far failed to do more android back.
        Does the mother board is the problem?

        sorry for bad english again…

        • http://wugfresh.com/ WugFresh

          Strange. That picture looks like everything went correctly. Try opening the toolkit options menu, then go the ‘Flash Stock’ tab > and Check ‘Enable Force Flash Mode’. Then try flashing the old Jelly Bean 4.3.0 (JSS15J). Also, can you try using a different USB cable and USB port if you have one. It could be the motherboard, but I wouldn’t give up yet.

          • Leonardo Floresta Nascimento

            And now,Like magic,the tablet as working great….after many hours im turn in on….and after his start Android and for are working… Yep…this is realy crazy

            For now…tks for the suporte!!!!

  • Guest

    I have 4.4.4 using a nexus 7 (2014). I just finally updated and I can’t get it to root. It is saying it is unlocked, as I have rooted it from 4.4.2 to 4.4.3 and on a friends nexus but using an earlier version of the program, 4.4.3 to 4.4.4. I have tried unlocking it again in case and it basically resets the tablet but does nothing else. It does go through bootloader sequence before it reloads my old home page. I have tried to root and it goes through the motions but doesn’t add SU to my tablet and no root.

    • http://wugfresh.com/ WugFresh

      Are you certain you selected the correct device and build in the toolkit? There are four Nexus 7’s to chose from.

  • https://plus.google.com/u/0/+ChristopherLarsen Christopher Larsen

    Been using the NRT heavily ever since I got into Nexus Devices and more recently ROMS, I’m a huge fan and I tell all my Nexus toting friends to use your software. I did however notice a bug that I can reproduce 100% of the time. Launch Advanced Utilities -> Push/Pull Files, then select the “Push Files” radio button, then click the “Push Files/Folder” button and select 2 files and then click “Open”. You will get the error that I’ve attached to this post. If you need/want more info or whatever I can be reached through G+ or Hangouts.

    Edit: It didn’t allow me to upload an image, so the error is:

    AutoIt Error

    “Line 21075 (File “path to NexusRootToolkit.exe”):

    Error: Subscript used on non-accessible variable.

    • http://wugfresh.com/ WugFresh

      Thank you. I will check it out and fix in the next release. Also thank you for actually describing what you did to produce the error. You have no idea how many people send me messages that just say: “It didn’t work. Help”. Cheers. Happy to hear you like NRT.

      • http://wugfresh.com/ WugFresh

        @disqus_48ZrUtddDc:disqus I have figured out the problem for that and made the fix, will be included in v1.8.7. Thanks again for reporting this.

  • Dallas Dorrington

    Hey Wugfresh, Thanks heaps eh buddy. You really got me out of a pickle. My Samsung Google Nexus S GT-I9023 died in a big way. The GSM chip fried itself leaving me with no phone. I took the phone to Samsung and they said it needed a new mainboard and this would set me back $200.00 Australian. The phone cost me $300.00 back in 9/2011 brand new. I desided that was too much. So here’s how I fixed the phone. We have a website in Aust’ called “GUMTREE” (www[dot]gumtree[dot]com[dot]au) where people can sell/buy things. So I put up a WANTED ad for a Nexus S GT-I9023 with a broken screen. I got a reply 8days later with a guy wanting to sell his Nexus S for $50.00 and it had a broken screen but otherwise it worked great. My phone was in great condition because it was always in a case to protect it. (Might of been why it overheated and burnt out the GSM chip) So i stripped both phones down and swapped out mainboards which was very easy to do. The phone I just brought had some weard Rom on it (Android 4.2.2 custom) and I hated it so i used your little program and wiped the phone and put the stock Google rom on it Android 4.0.4 ICS I then let the phone do a F.O.T.A. update to 4.1.3 Jellybean and this fixed all the things wrong with the phone and besides I was used to 4.1.3JB because my own phone had it on it. I fixed my phone for $50.00 and 2 hours work I’m now a happy little camper.
    Thanks again

    Hello. Love the program, but I have a possible bug report:

    Galaxy Nexus GSM. Tried to backup a single app from the backup section on the main screen. I get the error:

    “AutoIt Error

    Line 18387 (file “c:program files (x86)WugFresh DevelopmentNexusRootToolkit.exe”):

    Error: Subscript used on non-accessible variable.

    ADB was working, and the device was connected, according to the popup message. This happens right after the message shows up that says “Populating App List”

    • http://wugfresh.com/ WugFresh

      Interesting, that hasn’t happened to me. I will see if I can figure out what caused that. Thank you for the info.

      • Jim Penny

        Yeah. It set Bluestacks as the default device when the nexus was connected. Once I shut down Bluestacks, it all worked fine. I intend to convert the device to F2FS soon, and am going to be using NRT to do the flashing once the file system is changed. Do you know offhand if there will be any problems with doing it this way?

        • http://wugfresh.com/ WugFresh

          Thanks for letting me what caused it. I just added a quick line of code so that if it fails populating the app list, it will just give a blank pull-down menu, rather than crashing on you with that error.

          Regarding your question, as long as the files you are flashing are designed for f2fs, it should be fine. The toolkit performs the standard “fastboot flash” cmd’s, so changing the file system first shouldn’t be a problem. Cheers

      • Jim Penny

        It was Bluestacks android emulator. NRT wasn’t able to differentiate between the two devices, and kept trying to take information from it instead of the GNex.

    • http://wugfresh.com/ WugFresh

      @jimpenny:disqus thanks again for reporting this. Added a fix in this 1.8.7 release so this behavior wont occur if something is interfering with it like bluestacks – it just populates a blank pull down instead.

  • linuxbaby03

  • Fernando Romero

    Your app is really good. It worked smoothly on my Nexus 7 (2013) Wi Fi with Kit Kat 4.4.4. However I got a minor bug: After rooting process, the Cast Screen option on the quick configuration menu just disappeared. The cast screen option on the Chromecast app is there but it can’t recognize my chromecast device.
    The fun thing here is that I am able to cast fine through the regular enabled Chromecast apps like Netflix or Youtube, so it is not a Chormecast config issue.

    Hope you can help with this.

  • Matt

    Can I unroot without a PC? My mini USB is fried and I need to send it in for warranty.. But want to unroot first. Any ideas?

    • http://wugfresh.com/ WugFresh

      Are you running a custom ROM or stock? Are you running a custom recovery or stock?

      • Matt

        Should be stock ROM and recovery. I rooted and unlocked with toolkit v1.8.6 on version 4.4.2 and then mistakenly updated the OS to 4.4.4 and never re-rooted again

        I would run the toolkit again but can’t get the Nexus to be recognized by any PC.. Always allows up as unknown device

        • http://wugfresh.com/ WugFresh

          Then you are in luck. You must follow these steps in the exact order:
          1. Download & Install: https://play.google.com/store/apps/details?id=net.segv11.bootunlocker

          2. Grant that app Superuser permissions, use it to reset the tamper flag (if applicable to your device) and also to re-lock your device.
          3. Reboot your device to make SURE that the little unlock icon on the ‘Google’ screen is no longer there (it will just say ‘Google’ with a black background)

          4. Now once you are certain that your are relocked, open Busybox (if you have it), and hit Uninstall
          5. Now open SuperSU > Settings > Full Unroot
          6. Then perform a factory reset (this will wipe everything): Settings > Backup & reset > ‘Factory data reset’
          7. That’s it. Your device will be wiped, unrooted, relocked, and stock (assuming you still have stock recovery and are running the stock ROM).

          Cheers.

          Edit…. Wait, you aren’t rooted? If you aren’t rooted, you can’t relock, or do anything I described above. You would need a usb connection working then.

          • Matt

            It took me awhile to get all the data backed up and I’m ready to do this now

            When I download the boot unlocker it says I need to have a rooted device to use. My device is not rooted, but unlocked.

            Any ideas how I can modify the directions to do this?

            Thanks!

      • Matt

        Should be stock for both. I rooted and then mistakenly updated to 4.4.4 a few days later… and have not rerooted since

  • Daryle Edmond Dakis

    Hello. Thanks for this great tool. I need to ask, the Nandroid backup feature, where does it store the back up? Thanks again.

    • http://wugfresh.com/ WugFresh

      On the device sdcard, afterwards it uses adb pull to store it on your computer wherever you specify. The default directory is: PROGRAM_FILESWugFresh Developmentnexusbackupcustom-recovery-backups*

      • Daryle Edmond Dakis

        So it stores the backup on the sdcard temporarily only, correct? I asked because I have no idea how much space it would use. I have a Nexus 5 with 3.3GB free space. Would that suffice?

  • Sakif

    I’ve installed the drivers for my nexus 5
    onto my PC running on windows 7 including the drivers for adb debugging . However, the RSA fingerprint that is suppose to show up on my phone when connected in adb debugging mode does not show up when the NRT is opened. Can you please help me.

  • kopfarzt

    Hello, does NRT handle backup/restore of multiple user accounts?

  • Dave McAdams

    Thanks for the great tool and the steady enhancements. I have been thinking of updating to KitKat with the new CyanogenMod installer. If I choose to go back to a stock build is it as easy ass using the Nexus Root Toolkit to install a Google image?

    WHAT HAPPENS WHEN YOU START A FULL NANDROID /W BACKUP (My Device: nexus 7 Kot49h Only Wifi 2012) WITHOUT UNLOCKED BOOTLOADER??????

    • http://wugfresh.com/ WugFresh

      It won’t let you unless your bootloader is unlocked. Full nandroid are one of the benefits of being unlocked. Your only backup options before hand are android backup files, and just copy pasting anything from your sdcard on to your computer. Easy on the caps lock, its the equivalent of screaming at someone.

    • http://wugfresh.com/ WugFresh

      Thank you! Yes, I probably should fork the backup stuff into another app – those adb backup features should work for any kitkat device, same deal with the screen recording (all 4.4 devices).

  • kopfarzt

    Before rooting I need to know what would happen on a tablet with multiple user accounts (multi-user feature)… Does NRT support backing up multiple users? Do I have to make a manual backup for every user? How would this best be done? Is there an FAQ somewhere that I did not find? Does nobody else have this problem? :-)
    Thank you!

    • http://wugfresh.com/ WugFresh

      I never did the multi user thing myself, so I didn’t run into this. A quick Google search is telling me that adb backup only works on the primary user. I found a thread where someone said they tried to use my kit on the secondary users with adb backup and it just returned a 0KB file.

      Looks like you would need root so you could use Titanium backup pro with multiple profiles option, or just make full nandroids. I know that doesn’t help you if you aren’t unlocked yet, but this seems to be be case.

      I haven’t seen any dev/app address this issue. I guess multi-user is still relatively new. Hopefully Google will improve adb backup in the future.

    hey guys, i need help. ive had my nexus 4 formatted and all data and every single thing that can be wiped has been wiped all i have is the bootloader and when i try booting my phone it just stays on the google screen. i have no operating system on it or no back up data and when i plug my usb in to my pc it doesnt find the driver :( c am i tottaly screwed or is there a way back for me?

    • http://wugfresh.com/ WugFresh

      “Flash Stock + Unroot” ‘softbrick’ mode. Follow the instructions. You will have to boot your device into bootloader mode and configure the fastboot driver, which you should be able to do – then you can get everything back up and working.

  • Brian Arisius

I’m a total novice to Android, got into this for a CarPuter project on my electric car. Then I got the added bonus after rooting to also help me with installing a custom ROM and GAPPS. Dang! I put some jingle in your pocket in appreciation to your hard work. I’m a software developer and know the hard work it takes to bring these projects to life.

  • sainokawara

    I have used NRT since 1.7.8 or so to Flash Stock many times. When I first got my Nexus 7 2013, I could access it as an MTP Device. However, I slowly lost the ability to connect as an MTP Device and by about 1.8.3 or so, I could only connect as CAMERA in USB Debug Mode. I really didn’t pursue this problem because I had no real need to connect as an MTP device, UNTIL NOW! It is not a USB driver issue. It appears that some “device identifier” stored on the Nexus 7 has been “corrupted” which results in a “WUDFHostProblem” (Time-out) during MTP driver update/install. I have done several Flash Stocks but the problem persists. Is there some kind of “Super” Flash Stock that is guaranteed to update every conceivable “device identifier” stored anywhere so that I can again access my Nexus 7 as an MTP Device using Windows Explorer or other programs?

    • http://wugfresh.com/ WugFresh

      Flashing stock does wipe everything. You could go to ‘advanced utilities’ > launch cmd prompt > and with your device in bootloader mode, type the cmd’s:

      fastboot erase system
      fastboot format system

      Then reflash stock. If that doesn’t work, its either a hardware issue, or related to something (configuration) with your comp.

  • Raja Sekhar

  • ronjcar

    I am trying to get my Nexus 7 v2 back up and running. I can’t get it past the screen that says “Google”. I can’t get my computer to allow me to use any of the ADB connections. The only one that seems to work is the Flash Stock + Unroot (Soft-Bricked/Bootloop). It brings up the cmd screen and runs some things, but they all say FAILED. It tells me to press any key to exit and nothing on my tablet has changed. I have tried everything the instructions have told me to, but nothing. It seems nothing can talk to my tablet. Anyway to force my tablet to except this stuff. My N7 goes up on the Device Manager list of windows, so it is being recognized. I can get to the bootloader screen also. Not sure what my next step is. Please help. Thanks.

    • http://wugfresh.com/ WugFresh

      Have you unlocked your device yet? Unlocking is a prerequisite for flashing stock. If you have unlocked, please post a screenshot of the failed flash. Cheers.

      • ronjcar

        It says on the bootloader screen that my locked state is locked. How can I change that without my tablet turning on? I can only get to the startup screen that says “Google” and this bootloader screen.

        • ronjcar

          I see now the unlock section of the Toolkit. I was hitting the OK button I think each time and it would not do anything. I now have the Unlock bootloader screen on my tablet and have clicked yes. Pressed the power button and nothing. Seems to just stay highlighted on Yes and does not change from there.

          • http://wugfresh.com/ WugFresh

            Try alternate USB cord, and/or port. Or try removing the usb cable when you see that screen before pressing the Yes (via the power button).

          • zeut99

            I am having the same problem with it getting stuck on the “unlock bootloader” screen after trying to run the unlock tool. Also tried removing USB cable when I see the screen, does not change anything. Otherwise my situation is exactly the same as the original post from ronjcar.

        • http://wugfresh.com/ WugFresh

          You don’t need your device to be on to unlock. Just stay in bootloader mode, and use the toolkits unlock button. It will ask you if you want to ‘automatically boot into bootloader’, or if your want to do it manually. Chose the option to do it manually. Cheers.

  • Rocky

    i have used this toolkit for as long as i have gotten my nexus 4. never had any problems. until latest update. as soon as app says “rooting” after phone reboots, i get this error message “line 19433 (file “C:program files (x86)wugfresh developmentnexusroottoolkit.exe”):

    error: variable used without being declared

    • http://wugfresh.com/ WugFresh

      Please try again. I have never received any errors when rooting. And looking at my code, I am really unsure how that error could even be present at that point. Please confirm you are running v1.8.7. Also, during the root procedure don’t press other toolkit buttons.

        i never press any buttons. i let the process complete fully before doing anything else. anyways i did a manual root as i did a clean install and didn’t work. thanks for the program anyways. always was useful since day 1 i got it.

        • http://wugfresh.com/ WugFresh

          I am a bit confused. I would to try and reproduce the error if I can, but I don’t understand what you are describing. “i did a manual root as i did a clean install and didn’t work” .. I don’t know what this means.

          • Dan Yargici

            I just experienced the exact same error. Nexus 4. Seemed to happen right at the end after the final reboot, just after it said device detected…

            Anyways, it seems to have rooted fine, regardless.

  • Nirjhar Mistry

    Hi! I’m getting this error message all time. I did reinstall the program but still having the same problem. I’m on windows 8.1 64bit Pro.

    • http://wugfresh.com/ WugFresh

      I run win 8.1 64bit, and I have tested this program extensively on every supported windows OS (xp–>8.1, 32/64bit); so this error you are getting is not related to my program, but rather, windows specific. Have you tried basic windows clean-up, and maintenance trouble-shooting, like running ccleaner for registry errors. I have never even heard of gdipp until you posted that. But here is the official page for it. https://code.google.com/p/gdipp/ <<- did you install this? Maybe you made a bad install. Sorry man, but this program is totally not related to my program. That is the most I can help.

      • Nirjhar Mistry

        Yup! I had used ccleaner cuople of weeks back. BTW your program is up and running but every time when I’m trying to do someting via nrt it’s poping up but the work done eventually without error .

    after updating the app to the latest version 1.8.7 whenever I click on push files and folder, after entering the location when clicked on Ok the program gives a popup saying Done! and when i click on ok the app closes.

    I tried uninstalling and re installing the app again! no go.

  • CVB

    I have a Nexus 4.4.4 and everytime I go to do the pda net drivers and click ok some downlad and others do not. I am trying not to ruin my phone. help please.

    • http://wugfresh.com/ WugFresh

      Maybe try solution #1 instead. Or proceed to the driver test. Just an FYI – if you configure your drivers incorrectly, its not going to ruin your phone.. the program simply won’t work, and you will get a message that it can’t find your device. So need to worry. Just attempt to configure your drivers, run the driver test.. and if it works, proceed – if it doesn’t try again with another solution.

  • CVB

    Hey I have nexus 4.4.4 and every time i go to do the pda net drivers some download and others do not. i really dont want to mess my phone up please help.

  • jjfabbsy

    Hi – when attempting to backup SD card on android 4.4.4 – the toolkit says the device needs to be UNLOCKED first. Does this mean not on lock screen or the type of unlocked that wipes everything? Also what is the best backup option to backup EVERYTHING including virtual SD – so that I can restore a complete mirror of my pre-rooted device? Thanks for the software and will of course donate post-root :) p.s using Nexus 10

    • http://wugfresh.com/ WugFresh

      Hey, I really need to add a detailed response to this in the FAQ, and my apologies for the late response.
      – Toolkit unlocks the bootloader, which factory resets; Nexus devices don’t have an ext-sdcard partition so factory reseting wipes EVERYTHING including virtual sd.
      – The best backup solutions are available post-unlock+root such as full nandroids, and powerful root apps like Titanium Backup
      – The most complete (and recommended) backup solution and procedure with a locked device is as follows:

      1.) Create an androidbackup with neither shared nor system apps checked. The reason being (not to check them), is because ‘shared data’ attempts to backup things like your pictures and some sdcard data but from testing seems to do an incomplete job – resulting in a much larger backup file, but a false sense that you have everything backed up. Checking ‘system’ data is not recommended because restoring system data is known to potentially cause issues (better to re-configure system settings manually), and will definitely cause problems if you attempt to restore the system data on a different ROM or version of android. If you are currently running the same version of android that you plan on running post-unlocking, then backing up and restoring system data might actually work for you (and save you some time), but it is recommended to also make another androidbackupfile without system data, incase the one where its included doesn’t work so well for you.

      2.) Manually backup your important non-app data like pictures/videos/music/documents that are on your sdcard via copy+paste with windows explorer or with cloud storage. Also backup any folders on your sdcard that appear to be auto-created by games on your device. Some game apps download a lot of extra content and don’t save that stuff in the standard app/data dir but rather store it in some sdcard dir. If you want to be super safe, you could just backup your entire sdcard and then restore stuff back selectively.

      3.) Backup SMS and call logs if you care to keep that. You could also backup contacts however they more likely auto-synced with your gmail account.

      4.) Unlock and root your device.

      5.) Sign into your primary gmail during initial setup and let google play automatically restore your apps. Androidbackupfiles do not backup your PAID apps, they do however backup your FREE apps + app data for BOTH your free and paid apps – so you must let google auto-restore your apps first.

      6.) Restore your androidbackupfile.

      7.) Reconfigure your system settings manually (like email accounts, stock home launcher layout, etc)

      8.) Copy+paste back any sdcard stuff you want

      That’s it.

      This will give you the most complete and cleanest restore possible. The main annoyance will be re-setting up your email accounts and homescreen layout (if you use the stock android home launcher); other than that, you will have everything back and be back to where you started.

      Like I mentioned, once unlocked+rooted you have all the best backup options available; that is why, in the future it is recommended (in my opinion) to unlock a Nexus device right away when you get it, so you can avoid the hassle of backing up without full system access.

      Hope that helps. I will clean this post response up and move it to the FAQs asap. Cheers.

  • Jay

    Hi
    Thanks for your gr8 work
    I am planning to buy nexus 7 lte. does still these are having issues …
    and after unlocking > root>
    does the warranty is going to void….
    or after relocking and using unroot option. …I would again get warranty back……
    plz rply…thanks …

    • http://wugfresh.com/ WugFresh

      Unlocking may void your warranty however re-locking your device with the toolkit will make it impossible to detect that it was ever unlocked. Hope that helps.

  • Emiliano Parizzi

    It’s not clear if unlocking the device wipes media data (pictures, videos, songs)… Most recovery full wipes doesn’t wipe media. Anyway, if it does wipe media, how to back it up if the backup data/media needs the device to be unlocked…..?

  • FuMiYu

    hello, im using the modified rom cataclysm 4.4.2 for my nexus 5, i’d like to install TWRP for it using Nexus tool kit, but i got stuck in download modified_boot_img_4.4.2, it completed downloading but has a mismatch check, pls help !!! tks in advance

  • Bob F

    I successfully did a “Create Android Backup File” and after “Restore” all my SMS data is missing. Was I mistaken in assuming the Tool Tip saying “…backup file with all your user apps+data, system apps+data and shared data” would include SMS data?

    • http://wugfresh.com/ WugFresh

      There is a special SMS backup feature as well. That said, I believe sms gets stored in an sql database
      here: /data/data/com.android.providers/telephony/databases/mmssms.db, which would be considered system data. You could try using the paid app Titanium Backup which can unpack ab files, and try to selectively restore the phone/messaging app data and see if that works. Please report back. Cheers.

    hello i have a problem: every time i try to root or unlock,it tells me that “ADB device was not found” and i did all the driver installation/configuration guide

  • Lisa

    I am trying to recover data from my soft-bricked Nexus 4. Can I use the toolkit for this? I can’t seem to make it work because the phone is stuck in fastboot, locked.

    • http://wugfresh.com/ WugFresh

      If the bootloader is locked, there is very little you can do. Your best option is to try and wipe cache (JUST cache, NOT data & cache – aka ‘factory reset’) with the stock recovery. Without the toolkit, in bootloader mode;

      – Switch the big green START to the red RECOVERY via volume keys, then press power to select; you’ll see an image of an Android robot with a red exclamation mark and the words “No command.”
      – While holding down the Power button, press the Volume Up button.
      – Use the volume buttons to scroll to “wipe cache partition” and press the Power button to select it.

      Hopefully this will allow you to boot up. If so, backup your data, and consider unlocking your bootloader and performing a full factory flash via “Flash Stock + Unroot”. Cheers.

      Edit, here I found a youtube video: http://is.gd/wipecache_n4

      • Lisa

        Thanks for this, I was able to wipe the cache using your directions. Unfortunately, though, the phone would not boot up after that. I tried a couple times and now something extra-weird is happening: the phone won’t power down. When I hold down the power button, it just goes back into the loop (with the Google circles going in and out).

        • http://wugfresh.com/ WugFresh

          Unfortunately if your bootloader is locked, and that’s happening – recovering any data is not going to be possible.

          To get your device working, try doing a factory reset from stock recovery. If that doesn’t work, use the toolkit to unlock.. And then use “Flash stock + unroot” with “softbrick/bootloop” checked, and follow the instructions.

          • Lisa

            Okay, thanks, I lost the data but at least I have my phone back. Have no idea how it got into that state! Thanks for helping me get it back!

    You are a genius! I was running Android L on my Nexus 5 and wanted to take it back to 4.4.4 After flash, phone would not boot past Google screen. Refreshing did nothing. Your program fixed EVERYTHING with a couple of clicks. I will be donating to you.

    Can Nexus Root Toolkit be used to root Android One too?

    • http://wugfresh.com/ WugFresh

      You mean a Nexus One? No, Google doesn’t support that older device the same way, nor do I have one to play around with. If I got my hands on one, I would probably try and support it for nostalgia sake.

    • Daniel DS

      No.

  • Joe knows who I am.

    First, thank you for an amazing Toolkit! While I’m fairly new to rooting, I’ve successfully jailbroken Apple products previously and this Toolkit is a welcome, well thought out, versatile one.

    I’m in the process of rooting my Samsung Google Nexus S, which I purchased as an unlocked device direct from Google and run on T-Mobile. I successfully installed the drivers and proceeded through the unlock process. For all intents and purposes it appears to have been at least partially successful. I received the “Success” message, went through the ADB Bootloader/Fastboot process, reverted to stock, and it’s unlocked.

    However, I’ve been using QBking77’s video, which is not exactly the same model, but appears to be as close as I could find to mine which uses the Toolkit. When I attempt to Root the phone while also Flashing a Custom Recovery, I receive the script message that the ADB Device was not found. In addition to being unlocked, I’ve unlocked Developer mode, activated USB debugging, and switched off MTP. Should I proceed through the Full Driver Installation process again? Is there something that I might have missed in the steps? Prior to the Unlock, I did do a Backup, admittedly against your direction, of my System Apps +Data, though I am pretty sure that I relocated everything off of my phone. Could this have an effect?

    Any next steps or suggestions would be most helpful at this point as I’m stuck at the moment.

    Thanks again.

    Marc AKA: Joe knows…

  • Sean William Robertson

    Does not work on Nexus 7 (2012) I keep getting the “Fastboot device was not found” even though I am in bootloader as I do it, tried every single “solution” that is given and it will not work.

    • jason

      i used this and was able to root my n7 2012. go to the advanced tab and follow the instructions for deleting the drivers, that’s what i had to do.

      • Sean William Robertson

        Yea I managed to delete ALL my drivers for all my android devices then reboot then had to go through about 40 more steps to get it to work… not as simple as many people say. Basically “If your device is bricked, then the best thing to do is to not have it bricked… your welcome ;)

    • http://wugfresh.com/ WugFresh

      Sorry you are having difficulties. I made the driver installation as simple as humanly possible. Its not related to me software, its a windows/comp specific issue. My best recommendation would be to try an alternate usb port and/or cord and/or computer and try Solution#1 (automated) or Solution#4 (manual). I have tested and confirmed the driver installation on every single version and architecture of windows (xp to win10 tech-preview/enterprise), as well as many other users. I hope you get it resolved. (Also try disabling MTP on your device; settings > storage > menu item in upper right > mtp > uncheck).

      • Sean William Robertson

        There was nothing wrong with the software. The device I was trying to fix was just in the worst possible state, it was bricked at the boot animation, developer options were never enabled, it was bricked so obviously couldn’t enable or disable any MTP options, and the bootloader was locked and the PC wouldn’t recognize it, it would show up for a second and try to install the drivers but would always fail so the software kept saying “fastboot device not detected”. After a couple of hours using every bit of advice I could find I finally managed to unlock the bootloader and I just kept hitting retry on the softbrick +unroot option till it eventually worked.

  • jason

    i have 4.4.4 on my 2012 and i want to go back to 4.3, is this possible?

    • http://wugfresh.com/ WugFresh

      Yes, you can flash any available android version to your device easily with the toolkit. When you hit the flash stock + unroot button, there is a pull down menu where you can select which build you want to flash. Cheers.

  • http://richardleecagle.com/ Richard Cagle

    This is a lifesaver. Due to some irresponsible rooting/experimenting, I’d got my phone stuck in a bootloop. I was able to flash back to stock and OEM Lock it to prevent me from ever bricking it again. WugFresh, many thanks.

  • Connor

    Quick question, I’m a flashing/rooting noob and I used CM installer to put CM on my Nexus 7, and now it is stuck on the CM boot animation, it’s rooted, unlocked and I am able to access the boot-loader, will this work for me? I need to use it on a different computer to normal, so it won’t have any drivers for it.

  • Irsan Ehc

    I can on/boot my nexus despite having broken power button.

    Combination of, hold volume button (down) then insert charger, the nexus 4 will boot to fastboot mode.

    Then using NRT just reboot the nexus 4. And now! The nexus 4 is on!

    Thanks a lot to WF!

  • Markus Baumstamm

    Great work!!

    I was rooting Nexus 4 running on KitKat 4.4.4 and it ran smoothly and all my data is still there without using any recovery.

    How is that possible? You wrote, that everything gets wiped…Root works, so it ran through perfectly ;)

  • Dwight Spade

    my nexus 7 2012 gsm crashed and i could not get it to master reset I am trying to flash back to factory but I keep getting a bootloader not supported message. This update requires bootloader 4.23 mine is 4.13, I was wondering if you could give me some help to get past this problem

    • http://wugfresh.com/ WugFresh

      Enable force flash mode in the toolkit options.

  • Timothy Smith

    Hi WugFresh,

    My nexus 4 is suffering from softbricked/ boot loop problem. To make matters worse my usb debugging is NOT enabled.

    I am not able to unlock bootloader and “ADB device not found” error is coming which I believe is because my usb debugging is not enabled.

    I tried Flash Stock + unroot option but as I said before bootloader is locked and since usb debugging cannot be enabled (bootloop issue) I am confused. Can you guide me or point me to the steps that can help me recover my phone?

    • http://wugfresh.com/ WugFresh

      You can unlock and flash stock purely in bootloader mode. No USB debug required. The unlock script asks if you want to start in bootloader mode. Do that. Then flash stock + unroot with softbrick bootloop mode.

    Hello all,

    So my Nexus 7 (2013) is stuck on a boot loop where it only displays the Google screen – endlessly. I have the “Force Flash” enabled and when I attempt to run the ‘Flash Stock + Unroot’ option for a soft-bricked/Bootloop unit it just pulls up and shows:

    It will sit here like this for hours, not doing anything. Does this process normally take longer, and I am just being impatient? If I press the power button on my tablet in the midst of this it finally pulls up the following text…

    • http://wugfresh.com/ WugFresh

      First thing to try would be an alternate USB port and/or cable. Also try rebooting your computer. Those errors are indicative of a wonky USB connection. To answer your first question; No – erasing boot should like like 1 second. Let me know if you get everything resolved. Cheers.

      • Chad Thornley

        I appreciate the suggestion… but it seems to still be an issue. I have restarted my computer multiple times, and tried at least two other cables. Seems that it is still an issue though as it will just sit here for ages not changing at all. Attempting to unlock the bootloader freezes, as does anything else I seem to try… Any other thoughts??

        • Andrew Sheng

          Do you have an unlocked bootloader? Some sections says that the bootloader is locked. It should be unlocked to perform the Flash Stock + Unroot I believe.

    Hey,

    Im stuck on “Waiting for your device…” each time i try to root my Nexus 7: Asus 2012 Tablet :/

    The drivers test runs perfect, i’ve already reinstalled my drivers and still having the same problem, after a few minutes stuck on “Waiting for your device..” I get “Waiting for device operation timed out.” Plus alot of troubleshooting options that I have already tryed..

    Any opinions ?

    • http://wugfresh.com/ WugFresh

      Have you accepted the RSA security prompt, and checked ‘Always allow from this computer’ when you were setting up usb debugging? Looks something like this: http://i.imgur.com/UrlAtYU.png

      And when you say, it gets stuck on waiting for device.. at that stage, what state is your device in? Is it on? Or is stuck in bootloader mode? Are you 100% certain you selected the correct Nexus7 device in the kit? There are four available options to choose from.

    Hey there, Wug! Had Android L Developer review installed. Was a bit buggy and was interfering with other apps. This made reverting back to stock 4.4.4 an absolute breeze. Well done and thank you!

  • Adi

    Hi there,

    I am having a problem with unlocking the device. I run the toolkit and it sucessfully unlocks the device and shows up as unlocked at the bootloader screen. But when I need to restart in bootloader to do the flash stock + unroot, the device locks back up again. Any workaround to this?

  • Gaige

    Hey Wug, this program is extremely useful but I’m having a real hard time getting this to work with my nexus 7 2012 tablet. I’ve got Windows 8.1 64-bit to pick it up as an ADB device, but when it gets into fastboot it doesn’t recognise the device and windows pops up saying “USB device not recognised”. Device manager also says that the nexus is “Unknown USB Device (Device Descriptor Request Failed)” and I have no clue what I’m doing wrong. I’ve gone through the driver install tutorial and tried all four of the solutions but it’s still doing the exact same. Any clue as to what’s wrong?

  • Frank Bostick

    Wug,
    You guys are awesome. I’d banged my head against the wall trying to unroot and relock my Nexus 5 to receive the OTA for “L” in a few weeks. Id installed Clockwork mod recovery. Following the LONG way around using command prompts, etc got me no where. XDA suggested that you not use an automated script. Then I found your script. Boy am I glad that I found you. Getting back to stock was simple. Just a few clicks…. Took a few tries to get the phone locked again. But its all stock now and ready for the OTA.
    Thanks again! You will be seeing a donation for your hard work and simplifying the process so drastically!

Wait for SuperSU update to try again.” I checked out the lasted SuperSU.. guess there is a v2.14.. will this one (once you add it to the root toolkit, allow rooting of Lollipop I have?

    Thanks for this program btw, have never had any issues with it. works GREAT.

    • Ric

      Ah… just read in the Change Log… that SuperSU isn’t compatible at this time… sorry to post before reading the changelog.

    Hi there,
    With nexus 4, I tried to FLASH STOCK+UNROOT, it says – “AutoIt Error – Line 15664, Array variable has incorrect number of subscripts or subscript dimension range exceeded.” With v1.8.9. Please help me, my phone is needs it :(

    • Manan Duggal

      I’ve got the same exact problem on my nexus 5 :(

    • http://wugfresh.com/ WugFresh

      Looking into it. Working on an update.

      • Ajith Simha

        Thank you for a reply. Eagerly waiting for the update.
        Other than that, it’s a great tool. Awesome work :)

          v1.9.1 is up, all should be well now :)

      Change the build type to the latest official build. Same thing happened to me. By the way, as always, love you WugFresh! Don’t know what I would do without you!

  • Ardy

    HELP I’VE BEEN WAITING A DAY NOW.. NO RESPONSE. PLEASE.
    Hi. Long story short, my N5 has no OS installed (does have TWRP).
    Anyways, I downloaded the stock factory image from Google and attempted to flash it through the toolkit..
    It successfully imported, but whenever I type the md5 hash in the “Hashcheck Verification” screen, it is a mismatch (BUT I am typing the correct md5 checksum!).
    help… pls… Thanks!

  • Jay

    I have a AutoIt Error – Line 15664 error??

    • Manan Duggal

      If you’re getting the error when you try to unroot and flash stock so am I. Are you out on the Nexus 5?

      • Guest

        I figured it out,for CM11 users at least. So if you’re currently running CM11 switch the “build #” to that of a regular android build (probably to most recent version of 4.4.4) and then it should work. I’m now running the latest android L Dev preview and it’s great. Appreciate the software WugFresh!

      So, if the root of Android L is supported now? Thanks.

      • http://wugfresh.com/ WugFresh

        in v1.9.1 – yes.

  • sonofjon

    Can you relock without unrooting (the hover info box for OEM Unlock says to “use the ‘Flash Stock + Unroot’ before running this”)? I have used NRT to successfully unlock and root my Nexus 7 (2012). Now I want to lock the bootloader while keeping root. Can it be done with NRT?

    • http://wugfresh.com/ WugFresh

      Yes, relocking the bootlader will work without flashing stock first. That said, if you have problems in the future, it will make it more of a hassle to deal with. In particular, you will have to unlock the bootloader again (which wipes) if you needed to flash stock (or fastboot boot/flash any img file for that matter). If you understand these limitations of relocking the bootloader, and still want to (I am guessing for security reasons?), then for sure – go for it, you can disregard that info.

      • sonofjon

        Yes, for security reasons, and I understand the consequences. Thanks for the quick response. Awesome app!

    • http://wugfresh.com/ WugFresh

      • Andrea

        do you lost any data ???

        • http://wugfresh.com/ WugFresh

          Rooting doesn’t make you lose data, however you need to UNLOCK before you root. Unlocking causes a WIPE. So if you are not unlocked yet, then you must backup stuff first.

          If you are running KitKat and trying to flash Lollipop – the procedure will wipe data (unless you disable that in the settings menu.. however that is not recommended when going from KitKat to Lollipop).

  • Samuele Trotto

    I have installed factory image of Android 5.0 on my Nexus 5 with NRT. Now i must come back to stock 4.4.2 but the Full Driver Test doesn’t work! T.T I try it a lot of times, but it doesn’t work yet. I unistalled old drivers, instaled new drivers, used Google drivers and also Universal Drivers or Pdna Drivers..but it doesen’t work! Help me :(

    • http://wugfresh.com/ WugFresh

      Have you tried alternate usb ports and/or cables (also rebooting your computer?). You actually only need your fastboot drivers configured to flash stock – so you could use flash stock + unroot (softbrick/bootloop mode) and follow the instructions from there. If your computer can see your device when its in bootloader, then you should have no problems flashing stock and returning to 4.4.2.

  • monstrousmoran

    Hi im very much new to doing this type of thing and I kind need some help walking me through the process of unrooting my nexus 5. I had a friend root it and I have no use for it and I would like to get rid of it.I don’t have anything installed on my computer right now. Help please.

    • http://wugfresh.com/ WugFresh

      Check out one of the many videos on youtube. The toolkit walks you through everything. Backup anything you want to keep, then use “flash stock + unroot”, and then relock it – and you will be back to stock. http://www.xda-developers.com/android/factory-reset-unroot-nexus-xdatv/

      • monstrousmoran

        I looked at Babbling Booleans video and I followed it all the way through and when I tried to flash the stock ROM it said that I did not have the proper driver packages. And I installed them and it still did not work. I had USB debbuging on and I switched the USB ports as well to see of a different one would work. I lost the original charger for my nexus 5 and I’m using a Samsung tablet cord and that could be the issue please help

      You need to UNLOCK in order to root. Rooting does not wipe data, but unlocking does.

  • Carey Parks

    Hey Wug, small problem. My original N7 soft bricked. Trying your “Flash Stock & unroot” to get it going again. Seems to work until near the end it hits this:

    checking product…
    OKAY [ 0.030s]
    checking version-bootloader…
    OKAY [ 0.025s]
    sending ‘boot’ (4994 KB)…

    finished. total time: 0.269s

    I tried manually starting the device with normal power on, restart bootloader and recovery mode but nothing goes anywhere.

    I did some searching found I could unlock the bootloader via ADB, but ADB doesn’t find the bricked device, even tho your thing seems to be able to. The USB connect sound plays, but I guess I can’t put the device in the debug mode since it’s bricked. Ideas?

    Thanks for the great tool man.

    • http://wugfresh.com/ WugFresh

      You don’t need to be connected via ADB (on with usb-debug enabled) to unlock. You just be connected via FASTBOOT (bootloader mode). Just use the “Unlock” button, and follow the instructions it gives you to MANUALLY boot your device into bootloader mode, then proceed from there. Its fine that your device is messed up.. you just have to get the bootloader unlocked. Once its unlocked you can use “Flash Stock + Unroot” with softbrick/bootloop mode to get your device back to normal. Cheers!

      • Carey Parks

        Thanks for the quick reply! Sadly, the unlock runs, the device says “Unlocking bootloader” or something similar, and then goes dark. The USB is still connected, but sitting for 30 mins – nothing happens. Manually starting in bootloader (pwr & vol down) gives USB off sound and USB on sound. Running “Flash Stock & Reboot” goes like this:

        Flash Stock + Unroot…

        • http://wugfresh.com/ WugFresh

          You are going to want to try factory resetting and trying to unlock again (and flash stock again) https://support.google.com/nexus/answer/4596836?hl=en The factory reset will take care of your user data, so if your device is actually fried, then at least you wont have to worry about that. Actually, looking at the above text you posted. It looks like it already erased your data partition – so your device is already wiped. I would keep trying to get that bootloader unlocked… if you can, you will be all set. Try a different computer, a different usb port… etc. You could also try to issue the comamnds (NRT advanced utilities > launch cmd prompt):
          fastboot format system
          fastboot format data
          fastboot format cache

          • Carey Parks

            Thanks Wug, I’ll have a go this evening. Good to hear it’s wiped.

          • Carey Parks

            No joy getting past the lock, but as it seems any personal data has been wiped I’ll just do the warranty return and enjoy my 2013 N7. Thanks for the help, and thanks for the amazing tool.

    Please give me a hand.
    I just use your great NRT to restock my old nexus 7(2012) to 4.2.
    When im fail to ota update to 4.3, i use NRT to do the oem lock again. But the OTA is still failed.
    So i want use your NRT to upgrade to 4.4.2 directly.
    But the weird things happen. I can’t make Windows 7 recognize my nexus in fastboot, but i just use NRT to flash a stock rom in Fastboot!
    And then i try all the method i could found to find a fastboot driver but with no lucky.
    Is there sth wrong in my bootloader? How can i fix it?

    Here is my progress in brief:
    – a nexus 7(2012) with oem unlocked.
    – use NRT to flash stock “nakasi-jdq39-factory-c317339e” (fastboot driver is good)
    – ota update failed in stock 4.2
    – use NRT to do oem lock
    – oem lock is ok, but fastboot driver is not good anymore.

    • putt he

      I have tried your driver solution from #1 to #4.
      Also tried Asus and Google Universal Driver , All of them can server adb/mtp/ptp well but failed in fastboot.

      • http://wugfresh.com/ WugFresh

        Have you tried alternate USB ports and/or cables. Have you tried rebooting your comp. What does device manager show when you are in fastboot?

        • putt he

          I change the cable from my phone, and it worked!
          It’s make non sense.

      The toolkit lets you flash any official version of android available for your device, so when you press “Flash Stock + Unroot” there is a pull down menu to chose which version. Just chose the latest official jellybean for that gnex.

  • David Dupre

    Hey Wug. So my father has a nexus 7 2012 edition. It was never rooted. It updated to 4.4.4 recently as he is slow to getting around to updating it. Since he updated it started freezing up and restarting all the time. So he did a factory reset. It rebooted into recovery to factory reset and i guess it was wiping and suddenly went to a screen with the android guy with a red triangle and exclamation point. He so he let it sit for a bit and it did nothing. so he rebooted. it finally loaded into android, seemed to be fine all the sudden, but it rebooted itself again and now it doesnt go past the google screen. He can get into recovery but the problem is, its not unlocked and he cant enable usb debugging because he can’t get into the OS to enable it. Where should he go from here? He lives a couple hours away so i can mess with it myself. Just looking for the simplest way to get him back up and running. Even if we can install customer recovery and a ROM. Thats fine too. Thanks in advance.

    • http://wugfresh.com/ WugFresh

      You don’t need USB debug to unlock. Just get it into bootloader mode, and run the unlock script. There is a message where you can say your are manually starting in bootloader mode.

      Once unlocked, “flash stock + unroot” the latest android. You can relock afterwards if you like. Cheers.
