I have a rooted nexus 7 device. I kept getting ota updates for my tablet but every time it restarted, twrp showed up and i did not know how to do ota update with the root. So I decided to unroot and I ended up doing a system wipe. Can someone please help me to put the system image back and unroot the device afterwards?

Hi, I am new to the android scene and have a few questions.
Just wondering about the procedure for updating a rooted device, specifically the nexus 7. After I receive my nexus 7, I am planning on unlocking the bootloader, flashing CWM, and then rooting the device. I am not planning on using any custom roms. I am just going to be using stock JB.
If in the future I want to do an OTA update, what is the procedure for this?
From my understanding, it seems this is the procedure for doing an OTA update for rooted nexus 7:
1. unroot the device? (how do you unroot the device?). is this necessary?
2. use cwm to flash the stock recovery, because you won't be able to get the OTA with a custom recovery such as CWM. Is that correct?(also, where do you get the stock recovery??)
3. apply the OTA update. root will be gone.
4. flash CWM and re-root the device
And once I have succesfully OTA updated the nexus 7, re-flashed CWM, and re-rooted back the device, will I have to start from scratch (lose all data, settings, apps, etc?). I know unlocking the bootloader will wipe the device, but will the OTA update process require me to start over?
If I am missing any steps or have some things mixed up, please let me know. Also, if I were to use an OTA root keeper, what would the procedure be like or how would it change the procedure I listed above?
Thanks.
Haven't got my Nexus 7 yet but it looks pretty simple according to this thread: http://forum.xda-developers.com/showthread.php?t=1764794
Basically just need to have OTA RootKeeper installed beforehand, then disable signature verification in CWM and patch the OTA update. Then OTA Rootkeeper can restore root.
HTH
Hi guys,
A while back I rooted my sons Nexus 7. For some reason now it is unrooted and I can't get rid of SuperSU. It has the JellyBean 4.3 update on it. Will I be unable to remove SuperSU since the phone is unrooted now?
Thanks,
Rocky
Never mind I took care of the problem. I downloaded the Nexus Root Toolkit and flashed the stock image. Once it completed I locked the tablet. Maybe in the future I will reroot it again.
I have a rooted Nexus 7 (2012) with stock Android 4.4.2 (Build KOT49H). I have TWRP installed. Recently, I got a OTA update notification, which I chose to install. After downloading it, the tablet requested to reboot as usual, but it rebooted into TWRP and just stayed there. I had to select reboot in the TWRP menu. The tablet is still in 4.4.2 and now it doesn't notify me of any OTA (it just says "Your system is up to date").
Should I flash stock recovery to install the OTA?
Is the downloaded OTA still somewhere in the tablet?
How do I get the tablet to recognize the OTA again?
Thanks!
[OTA Captured] Android 4.4.4 KTU84P for the Nexus 7 2013
Nexus 7 2013 Wifi (flo) Over Air Update from KTU84L 4.4.3 to KTU84P 4.4.4
This only for Nexus 7 2013 Wifi Version
If you ran Towelroot on 4.4.3 and got root, then took this OTA, you will lose root (no surprise there). I was able to reinstall Towelroot and reroot. (SuperSU reports new binary required, then reports update failed, but after reboot I was rerooted.) Obviously, this only matters if your bootloader is locked.
Yesterday.
I lose root and custom recovery (cwm) after 4.4.4 OTA update on my Nexus 7.
Then I installed TowelRoot, applied the exploit and I gain root again... very very simple! No unlock bootloader needed or fastboot command...
Then with Rom Manager I reflashed custom recovery (cwm), flashed UPDATESuperSu.zip and uninstalled Towelroot apk....
recovery gone
This OTA (actually installed via Android system update) killed my recovery (TWRP) too.
I've reflashed TWRP 2.7.1.1 via fastboot, but I can't seem to get into recovery. Whenever I select Recovery from the bootloader, I get an opened-up android drawing with a red exclamation over him, sort of like the "No command" thing with my Nexus 4, only without "No command". Naturally, I tried holding Power+Vol-UP, but that didn't work like my Nexus 4. I can't seem make any key combination or duration of key hold work...
The happy ending is that I went back to TWRP 2.7.1.0 and I can get into recovery (and reflash SuperSU). Hard to believe there's really a problem with 2.7.1.1. Maybe I'll try the next version...
NRT works perfectly
I just used Nexus Root Toolkit with TWRP and worked perfectly fine for re-rooting.
Just I update the latest version 4.4.4. Its still not rooted from the beginning. Can anyone advice shall I change to run on ART on my tab which is not rooted. Thhhanks

I just updated to 6.0.1 (MMB29P on my nexus 6p and tried to root. I installed twrp via fastboot adb whatever and I get dead android guy. Twrp just will not install. I need to update for cm 13 so i stop getting internal error message at boot which drives me crazy. I do not want to downgrade so i can keep the January security updates but i might have to at this point.
