Yes - You can flash Android M Preview with NRT 2.0.5
- Google recently released Android M preview for N5, N6, N9 or NPlayer.  If you want to try it out (no root support just yet, but progress) feel free to flash it with NRT:

1. Download the preview factory pack from their dev page:

2. In NRT on the main interface chose 'Flash Stock + Unroot'

3. Select 'Other/Browse' and 'I downloaded a factory image myself that I would like to use instead'.  Enable 'Force Flash Mode'. > Hit 'OK'

4. NRT will prompt you to select the factory image from your computer with a file select window, simply navigate to wherever you downloaed the tgz factory preview pack and select it.

5. When prompted, paste the corresponding MD5 Hashvalue provided on googles M preview site.  For your reference:

Nexus 5 (GSM/LTE) 
"hammerhead" hammerhead-MPZ44Q-preview-55d76d3a.tgz
MD5: 9e2631b06c6525e401ceaae3677ff320

Nexus 6 
"shamu" shamu-MPZ44Q-preview-c1d6506a.tgz
MD5: 307cbf9dab0a38df4ab2639d02be12aa

Nexus 9 
"volantis" volantis-MPZ44Q-preview-d15ad483.tgz
MD5: 8989ce077510a1b814d58dcdb33d160e

Nexus Player 
"fugu" fugu-MPZ44Q-preview-2406ba05.tgz
MD5: 815902141a85cc65e7725f005cad31d5

6. Let NRT do it's thing and you will boot up M.  With the current NRT v2.0.5 on a Nexus9 you will have to hit the power button once to boot up after the flash.

That's it!  Enjoy ^_^

Stay tuned.  I have been working hard on v2.0.6 with lots of new enhancements - hopefully it will be ready for prime time soon!

Nexus Root Toolkit v2.0.5 Released!  - From the changelog:
 - Rebuilt entire downloading system to utilize wget instead of AutoIT’s inbuilt InetGet functions.
- New download system now supports HTTP/HTTPS proxy configuration.  Full frontend for managing user configurations in the toolkits options menu.
- Proxy configurations with username/password can be setup, and there is an option to re-prompt for the proxy password credentials each session.
- Added better information messages in the flash stock interface to help user chose the best configurations.
- Change the ‘Support Threads’ link to point the forums on
- Corrected the ‘Flash Stock + Unroot’ ‘no-force encrypt’ option to grab the no-force encrypt boot.img dependency based on the users selection of what they are about to flash rather than what they are currently running.
- All backup & restore apps updated to the latest available versions.
- Busybox free and Quick Reboot updated to the latest available versions.
- SDK platform-tools (adb/fastboot) updated to the latest available version.
- To ensure authenticity, all exe’s and installer files are now digital signed with a verified Comodo Code Signing certificate.
- Other small fixes and general code optimizations.

I also have been working on improving my site and adding/revising the troubleshooting info.  Made the dowload links more defined, and tried to lay things out a bit better.  Most notably there is a new forums section:

Moving forward I am encouraging everyone to try and utilize that as the primary means for contacting me with questions.  It's much easier for me when everything is in one place and is searchable for others.  I have the forums section setup with tapatalk now so I can easily manage and respond to those comments on-the-go from my phone/tablet.

That's all for now. Enjoy! ^_^

Hey +Wug Fresh, I have two questions:
If I want to update OTA, do I need to lock the phone? I wanted to go back full stock but I'm scared that Locking will delete my settings / Apps and so on. 
If I don't need to lock: Great, if I need to lock: Will the OEM Lock option in the toolkit reset my phone?

- My apologies to fastspeedtest, they did not do this.
- The culprit was devhost d-h .st
- On a previous version of NRT (v2.0.0), their link had a shady checkbox: "Download with Dev-Host Download Manager" that was checked by default.
- With this checkbox checked, their site was not delivering the genuine download but rather a crapware bundle.
- Suffice it to say that I will never use dev-host to host any file ever again.

As always, to avoid complications please remember to verify the hash of the download with what is provided on

The latest version of NRT is 2.0.2
md5: b726c4507f159f5c9397e6e6bc887050

And can be downloaded from the trusted mirrors on my site.

My apologies to anyone who downloaded that fake file.

Nexus Root Toolkit v1.9.9 Released! - this version brings lots of new features, enhancements and optimizations.  No more root kernels required, and a newer more organized advanced utilities interface.  Enjoy!  ^_^

From the changelog:
· New feature for flashing a build specific ‘No-forced Encryption’ boot.img [for Nexus 6 & 9]: Advanced Utilities > Fastboot Flash > Boot > ‘No-Force Encrypt’ button
· Root method no longer relies upon root_kernels, but rather utilizes Chainfires latest and greatest SuperSU.
· Added a dedicated ‘Vendor’ button in advanced utilities for flashing that image on the Nexus 9.
· Added new Fastboot Erase and Fastboot Format features (advanced utilities), which allow users to perform batch wipe operations after selecting the partitions with checkboxes.
· Added new ‘OEM Device Info’ button in advanced utilities ‘Quick Tools’
· Re-organized advanced utilities into top-level blocks ‘Fastboot Flash’ and ‘Fastboot Boot’ respectively; so previous features like ‘Restore Stock Recovery’ can now be found in a sub-gui after hitting Fastboot Flash ‘Recovery’ Button.
· Restore Stock Kernel script no longer performs a temp boot test operation, it just flashes it.
· Flash TWRP/CWM/PHILZ/OTHER scripts, now allow you to disable the additional operation of flashing ‘’ which is only needed the first time you flash an alternate recovery (so for example if you are just upgrading to a new version of TWRP, you can forgo flashing that zip and just have NRT flash the new version).
· Fastboot device detection now auto-retries to connect once if it doesn’t the first time.
· Updated the included adb/fastboot binaries to the latest platform-tools release from the SDK
· Added an automatic check to see if ‘Bluestacks’ application is running on start, to ask the user if they want NRT to close it (because this application causes conflicts with NRT)
· Bug fixes to multi-updater to deal with scenarios where not all files are available for a device yet (like TWRP currently for Nexus Player)
· Minor bug fixes, code optimizations, and feature enhancements.

Wishing you all a happy Thanksgiving tomorrow :)

NRT Alpha Squads - Looking to make official G+ tester circles for the Nexus devices I don't currently have on hand.  Developing NRT is already challenging enough in my limited free time but finding someone each time I need a device specific file tested is becoming tedious.  I could really use your help!

This way, I can just ping the group and whoever is free first can test.

File testing will typically only take 5-10 min and will be safe. Either it works (yay!) or it doesn't and you will have to force reboot.

- The Nexus Device (with unlocked bootloader)
- NRT or the SDK Installed

Looking to form alpha squads for the following devices:
- Nexus 10 (mantaray/manta)
- Nexus 9 Wifi (volantis/flounder)
- Nexus 9 Mobile (volantisg/flounder_lte)
- Nexus 7 2013 Wifi (razor/flo)
- Nexus 7 2013 Mobile (razorg/deb)
- Nexus 6 (shamu/shamu)
- Nexus 4 (occam/mako)

If you would like to join a squad, respond with your devices (codename) below, and I will add you to the appropriate G+ circle.

Thank you!

EDIT: Fastspeedtest claims they did not do this, and that my statement is unfair, but I can't verify that at this time.  Will update, when I find out more.  Please message me if you downloaded a bad installer.

Malware NOTICE - one of the third party hosts: that was delivering the NRT installer, had switched their link for some crapware installer using the NRT name.  Trying to make money at my expense, and attacking my reputation.

I am really upset by this, because now I am seeing claims that I did something malicious.

ALWAYS hashcheck your downloads with the hash I provide on so you can be certain you have downloaded the genuine installer.

The latest version of NRT is 2.0.2

Nexus Root Toolkit v2.0.0 Released! - Lots of enhancements + new features.  From the changelog:

· New dual-style intelligent ADB/FASTBOOT connectivity checking system.  Now users are able to start any NRT script from either fastboot or adb mode, and the toolkit will automatically detect their device state and continue from there.
· New ‘no-force encrypt’ flash stock option for N6/N9 that will allow users to use ‘No-wipe mode’ on their previously decrypted device, and retain their decryption (and data) when upgrading.
· New ‘Manual Masterlists’ importing, so users can get the latest masterlists even if the toolkit says ‘can’t access update server’
· New feature in advanced utilities for changing/resetting your devices display density.
· Live Log now has additional starting information, to make it easier to provide support.
· Re-built the Quick Flash (file assocations *.img) interface and included the ‘cache’ and ‘vendor’ buttons.
· Extra info when setting SuperSU beta, which informs the user that beta release SuperSU’s may not always be more recent than the latest stable.
· All ‘Flash Stock + Unroot’ options moved from the toolkits settings menu to the flash stock interface.
· Text revision on main interface to show that “Flash Stock + Unroot” can be used for “Restore/Upgrade/Downgrade”.
· Fastboot flash ‘Cache’ button added to advanced utilities and new quick flash (file assocations *.img) interface.
· Quick Tools are now fully dynamic with the new intelligent connectivity checking so the user no longer has to specify if they are in adb/fastboot mode.
· APK Installation now automatically checks for special characters in the file name that could prevent installation, and if present – removes them on-the-fly, then auto-renames them back to their original name – all without user interaction.
· No-Force Encrypt flashing script (Advanced Utilities > Fastboot Flash > Boot > No-Force Encrypt) now performs both fastboot erase and format so that it works properly on n9 (which disallows the fastboot format userdata cmd due to f2fs file system).
· Determined that the ‘can’t access update server’ is related to users having download managers installed on their machine, so NRT now recommends uninstalling those (for now).
· About NRT script now displays additional text to indicate ‘beta’ SuperSU being used.
· Settings.ini is now primed with the blank sections for improved organization and readability.
· On first run if SuperSU beta has a greater version number than stable it is set as the default (can be disabled in toolkit options).
· Improved ‘Other’ factory pack recognition scripts, to better identify factory packs that are not listed in the kit.

Next step will be making some major revisions to to make it easier to find answers to questions.  There may be some unexpected downtime but I will try my best to keep things running smoothly during the integration.  Stay tuned!

Also, will be aiming to integrate N9 LTE support either later today/tmrw.  I could use some testers if available.  Cheers!

Enjoy! ^_^

+Wug Fresh I was wondering if it was at all possible to work on a new feature that can install / flash OTA without doing the unroot return to stock method i am tired of
 un-rooting returning to stock firmware only to then re-root my device and then add custom recovery. is it at all posible to work on a feature that can remove custom recovery return to stock recovery temp remove root and then flash the ota firmware with option to keep user data or wipe clean after firmware is updated root is automatically restored and custom recovery is restored.

Update to - Over the past few weeks has been hard at work cranking out lots of instructional videos on #NexusRootToolkit  detailing and highlighting the various features/utilities.

To accommodate all these new helpful guides I have restructured and updated the dedicated 'Video Guides' page on my site.

He has plans to make even more videos, and I will be sure to add them as well.

Check it out, and be sure to like his videos if you find them helpful.

Please note – the experience with NRT is consistent across all the Nexus device so you can easily following along with any of these videos, regardless of which Nexus device you have. These videos are not made by me, special thanks to RootJunky, Babbling Boolean, DroidModderX, and Qbking77 for ...

i rooted my Nexus 10 with the nexus 10 root toolkit.
But when i try to update to android 5.01 the device give's an error.  (update provided by google) The only thing that works is to clear my cache and my nexus reboots normally.
Do you have any suggestions?
