Nexus Root Toolkit v1.8.5

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

VERSION 1.8.5  - 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 Android builds and Nexus devices are officially supported including the new Nexus 5, with full KitKat support for all the newly upgraded devices.  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.  The main changes in this release are improvements to the auto-downloader, custom automated driver configuration, and other general code enhancements and optimizations.  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.

    • 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

    • WugFresh

      Can you provide a screenshot.

      • M.F. Lawrey

        yes sir, sorry for both monitors

        • 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. 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?


    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?


  • GigaCode

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

  • 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- 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!!!!

    When its finally booted back up, please remember

    to re-enable USB debugging if you plan on using

  • Enrique Llanos

    Hi mate, any plan to update NRT to fit root Android L for the N5?

  • 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 :)

  • Austen Evans

    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” !!

  • MorcCrafak

    I Bricked my phone and testing the stock help :D

  • Vladimir Fomin

    What does that mean? I waited a half an hour after that press any key and exited. Nexus 7 Wifi tablet.

    – It may appear to be boot looping; just wait…

    NOTE: If this process was too quick and your device

    is still in bootloader mode, then flashing stock may

    have failed or been incomplete. Simply check the

    log above: if you notice it skipped steps because it

    didn’t meet certain requirements, like the bootloader

    or baseband version, then consider enabling ‘Force Flash’

    mode in the toolkits options menu and trying the

    ‘Flash Stock + Unroot’ processs again. Cheers.

  • 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.

    • 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

    Please add Android L support

    • Dying_in_this_Crap_World

      they will when a version comes out. They stated already that it’s not worth the effort to do it for a developers build when it might change

      I highly doubt the issue would be Windows 8.1. Always too easy to blame the OS.

    • WugFresh

      Not sure what the issue is, can you provide more details. I personally use Windows 8.1.

  • Gianni Metitieri

    Hi wugfresh can you add a torrent for next version? devhost download very slow today!!

      Sure, for this new 1.8.5 version, I added a “Magnet Torrent Link” under download.

  • Andrey Flyagin

    Wugfresh, please, please add fresh version of NRT to any torrent-tracker. It’s impossible to download it from that damn file-exchangers. Please.

    • WugFresh

      As per your request, I added this new version to a torrent tracker. Use the “Magnet Torrent Link”
