Hello , im new in this forum so sorry if i did something wrong...
about a month ago i rooted my Nexus 7 4.2.1 and everything went good ... until two days ago i couldnt connect to the google playstore and i had an update at the same day ... so what i did was kind of stupid ... i kept the root and upgraded to 4.2.2 hopefully it would fix the google playstore, but what happend is that the root is not activated but i still have the SU .. BUT busybox was gone and google playstore still wasnt conneting...
after a while i tried to unroot my tablet with nexus toolkit with version 4.2.1 (because there was no option for 4.2.2 yet) i did it and now my tablet nexus 7 is stuck in the google logo with a unlocked key underneath it ..... PLEASE HELP I HAVE TRIED EVERY THING YOU ARE MY LAST HOPE PLEASE PLEASE PLEASE :crying: :crying::crying:
Did you try downloading the official 4.2.2 factory images, and flashing them one by one via fastboot? http://forum.xda-developers.com/showthread.php?t=1907796
Hopefully you have a backup of /sdcard. This will bring you back to unrooted stock. You will then have to flash a recovery using fastboot, and then you can flash a Superuser or SuperSU zip to get root back.
I don't use toolkits. So I will be of no help there.
Hello , thank you very much for answering but im new in this rooting system so if you could please explain to me what to do ....
and no , i didnt backup anything....
my tablet now can go to the recovery mod i think (pressing the close button + volume UP + volume DOWN for 10 seconds) without a problem...

You dont need usb debugging when you flash things in fastboot mode. as for drivers, if you can see your device in device manager, right click on it then chose update driver, then navigate to the google_usb driver folder found in the sdk extras or on wugs toolkit raw driver install option.

Hi I have a Nexus 7 version (4.1.2 OTA).
I wanted to ask what the deal is or what I'm doing wrong. I purchased the full version of Nexus ToolKit 7. According to the instructions I made the unlocked bootloader and I wanted to root but each attempt failed.
I do not know what I could do wrong when root is fully automated.
PS: I also tried to reflash Stock Rom (4.1.2)
I enclose a picture attachments with an error message

Hi. Yes mam (usb debugging on) have a look to the attachment.
Toolkit me boot into fastboot then reboot then for something to fastboot loaded and back to android and trying to upload the files but nothing superuser is not recorded because of (read-only file system).
have a look on the attachment is there to see everything ...
yep same issue here - problem with the forum regs is unless you have enough posts you can't actually address the issue to the appropriate person can you? Anyway, able to unlock but then is unable to root and rest due to a permissions problem. have tried as administrator but of coure this doesn't make any difference.

You can try flashing CWM recovery and installing Superuser from there.
Download Superuser and copy it to your /sdcard
Flash CWM recovery
Install Superuser from CWM
????
Profit.

Thanks comminus - but I think that if we could do this then we wouldn't be using the tool kit.

Why not try before you give up? Nothing I suggested is even remotely challenging.
With your tablet booted normally plug it in to your computer and copy the superuser zip in my previous post to the Download directory on your Nexus 7 from Windows.
Judging by the first provided screenshot I can see that option 6 in that toolkit is for flashing recovery. Why not try that?
As far as how to install the zip from ClockworkMod (CWM), there are literally hundreds of threads and YouTube videos that will show you what to do. The better option is to spend a few minutes (literately. It only takes a few minutes.) to learn some basic fastboot commands. If you're willing to learn there are many people who will help.

Thx you for your post
But in the Nexus7 ToolKit can be done but is ClockworkMod must first rename (recovery restore files) but with da only when I have ROOT.
And why unnecessary to install CWM and resolve other problems I'll eat a connection. If "simply" can I ROOT who create me rich enough.

Choose #1 in your first screenshot.
After you install CWM make sure you boot recovery before a standard boot. On rebooting from CWM it will say something like "ROM may flash stock recovery on boot." and prompt with yes or no. Choose yes - this renames /system/recovery-from-boot.p and prevents the ROM from restoring stock recovery.

I'm not really sure what you're trying to say...
I tried quite a few times to root my Nexus 7 with the Nexus 7 toolkit, it hung every time when it was supposed to be installing SuperSU and BusyBox. Every time the last message I saw was "adbd already running as root", and it would just hang there. Everything else appeared to work properly. The only tool I was able to successfully use (more than once) was the Nexus Root Toolkit from Wugfresh http://forum.xda-developers.com/showthread.php?t=1766475. You may want to try that tool.

Oki THX u i try this tool...
I'm also having this same problem but here's my story:
Using the Nexus 1.5.4 Toolkit, I Unrooted + Flashed jzo54k, success. I locked OEM, success. I unlocked again, success. Then I ran the root process again, and it keeps freezing at the android recovery screen. Following the prompt in the toolkit, I walked away for a few hours hoping time would resolve the issue.
If you're wondering why I unlocked + rooted, and decided to unroot, lock, unlock, and root again, its because I'm super-noob to anything android related after version 1.5, I wanted to learn the processes after I found out I was having troubles with certian things after my Nexus 7 updated from 4.1 to 4.1.2
I am having the same issue as you. 4.1.2 is not rooting for me. I can't install CWM or TWRP because it needs to rename recovery files, and to do that you need to be rooted. If I boot in recovery I always get stock
Having the same issue with a stock 4.1.2. I can unlock no problem but I cannot get it rooted. Everything appears to have worked, but it is not rooted. If I revert back to 4.1.1 I can unlock, root, etc. without issue. I was able to root 4.1.1 and use the root keeper app to then update to 4.1.2 and I was rooted still. However, it would not let me install CWM or anything. ROM Manager says it was installed, but booting to recovery always too me to stock.
Any ideas?
Can you point me into the direction to downgrading?

I used Nexus Root Toolkit v1.5.4 and selected the "Flash Stock + Unroot" option. When prompted I choose the default 4.1.1 option and away it went.
To root my 32Gb on 4.1.2 I had to unlock the boot loader, flash the boot loader back to version 3.34, and then I successfully rooted using the nexus 7 toolkit.

FLASH THE OLDER BOOTLOADER DON'T BOOT IT!!!
i have a rooted nexus 10 , not unlocked no custom recovery , rooted it via tool kit , 4.22 update was available via ota so tablet notified me and when i intalled the update it stoped in the mid and saying error , and now when i restart my tablet after google logo android appears and under it "no command" , how should i fix it.
I got the similar issue.. i can't find out another solutions.. i have to reflash the factory image to 4.2 and OTA 4.2.1 and 4.2.2
then use toolkit again to root it.
since Factory image 4.2.2 has released. just flash to it , will be much easier.
Try to search it.. i saw the other one have the same issue..
A friend of me got the same problem and all he did was go into recovery mode and wipe cache. He got this problem because he updated via ota and he had the aosp browser without the original files on /system/app.
What you have to do is power off your nexus 10 and then press power-vol+ and vol- buttons together. When you get to the dead droid recovery menu, press all 3 buttons. You will get into the recovery options.
thank you guys n another thing... to recieve and install the ota updates succesfully do i have to unroot my tablet?

No; keep in mind that if you mod anything system related (apps, framework, build.prop), you'll need to restore it the way it was before actually running the install process.

The ROM you flashed is from my thread. I'm not sure why you think custom recovery remains available? Unless I've missed something else you did. It is overwritten by the stock ROM when flashed. Hence I clearly stated that custom recovery will no longer be available.
I don't know what "messed up" with the ROM?
I suggest you revisit the page you used and try the alternative method if you really fell the need to downgrade...
Well after 5 house of messing around i managed to ADB push CM11 too my device, Boot the phone then connect to my PC then re-flash 4.4.2 & root using this method > http://forum.xda-developers.com/showthread.php?t=2680789
Think ill just stick to 4.4.2 lol.

Hi
I have a major problem!
I was following a guide and downgreaded to 4.4.2 . Installed Root and Custom recovery.
Installed 4.4.4 according to the guide i cant find right now and everything was working as it should! I then installed all apps i need and also Xposed framework,Busybox and another all in one tool.
Now when i try to boot into recovery mode its gone!
How do i get recovery back in a easy way or do i need to redo the process again by downgrading ? How did i loose recovery so i can avoid it again?

you lost recovery by installing and updating busybox...as stated on this forum dozens of times you CAN'T UPDATE busybox if you're on NUT dual recovery... The fix is easy, just run the dual recovery installer in your pc and the recovery will be back. Busybox is included with the recovery, no need to install it. if you read the dual recovery known issues you would know this, just search next time... http://forum.xda-developers.com/showpost.php?p=43698321&postcount=2

Enable USB Debugging on your phone, make sure correct drivers are installed on pc, run the installer for the recovery and choose option 1. Installation on ROM rooted with SuperSU.
Make sure you autorize your pc on your phone screen if asked. I've reinstalled / updated recovery lots of times on several z2's and it never failed, as long as root is working the install should succeed...
Thank you!
yes well i had the files but it didnt work until i first installed the drivers from flashtool again. Also i installed the ADB drivers i the 4th options of this tool . Now its working. Thanks again!

There are no factory image flashable zips, as those have to be unpacked and flashed as individual partitions. However, there are OTA zips that you can sideload via ADB. If you're looking for a full Nougat factory image that you can flash with TWRP, you won't find it.
The index of all Nougat factory images and OTA updates are at http://www.xda-developers.com/facto...nexus-going-live-updated-with-nexus-6p-links/ and the OTA is listed down the page ... https://dl.google.com/dl/android/aosp/angler-ota-nrd90u-519758d5.zip
Finally, and most importantly for you, you need to be stock MM (right down to stock recovery) to apply a factory OTA via sideload. For a factory image update, you're actually much better off unpacking the factory image and flashing all partitions via fastboot, by following Heisenberg's guide. This would be the way to go right now, provided you have no problem booting into your bootloader.
The OTA can be quite normal flash with TWRP, without sideload
The simplest way out of your predicament would be to download nexus root toolkit here http://www.wugfresh.com/. This will let you flash stock, it will download all the files for you.
I am still trying to figure out what so urgent about it?!
You probably don't have ADB drivers installed or you're not in bootloader mode.
No need to make a big fuss about such tiny thing.

Actually I did install ADB driver, but it still doesn't work, right now my phone is in bootloop for 2 days and I can't do and don't know what to do about it
OK
1. Push the power button until your device is turned off.
2. after a minute or so, power on the device holding at the same time " Volum DOWN + POWER" until the device will turn on and you will see the FastBoot screen, then let go of the two buttons
3. While in Fastboot mode, make sure your PC manage to "see" your device. If it does, then move on . If it doesn't something is wrong with your ADB drivers and you need to fix this before moving on.
4. Assuming your ADB drivers are installed properly, you have three choices:
4.1 Make a clean install using the Google Factory Image Which will result in a lose of all user data and you will probably have a functioning device.
4,2 Use a toolkit such as Wugfresh's one and restore to a clean Install just as in section 4.1
4.3 You can try and change the flash-all.bat file that comes with Google factory images and remove the "-w" from the last line of the file. That will keep your data and will refresh your OS.
There you go.
