Unroot nexus7 without PC - Nexus 7 Q&A, Help & Troubleshooting

Hi,
Can you unroot the nexus7 without using a PC via TWRP or something and then load OEM stock image?
Because I can't connect to my PC via USB.

IF you are already on stock with the ability to accept an OTA, then possibly. To unroot, just delete superuser.apk from /system/app and su from /system/xbin. Although you would somehow need to get back to the stock recovery, perhaps you can find it in flashable form somewhere.

If you have supersu installed it has an option for full unroot

This would only remove superSU (from /sys) and wouldn't do anything else such as lock the bootloader

It removes supersu and the superuser binaries, aka root.
Besides you only asked for a unroot not a bootloader re-lock. Which is impossible without fastboot or a prior locked state back up of it pal. :/

Strange Root Issue

When I saw the port for ICS come out I got really excited and flashed it right away. Then I realized for whatever reason I didnt have SU permissions so I couldn't tether to my computer. I was disappointed but I thought, "no biggie, I'll just restore from my back up." When I flashed my back up the SU app was in my app drawer but I still couldn't tether. As a matter of fact I can't do anything that requires SU but the bootloader still reads unlocked. WTF?
I can't flash a new recovery either. I tried installing from ROM manager, I tried pushing it from my computer but I can't get to the recovery any more. ROM manager says that I have CWM 5.0.2.0 currently installed but I can't get to it at all. Again, WTF?

^clearly the phone is working perfectly fine with the stock ROM from the back up but obviously I want my SU back.
Root your phone and read the development thread versus making blog posts.

Thanks for not answering my questions. The bootloader is unlocked but I don't have root and I don't have access to recovery mode even tho ROM Manager says I have Clockwork Mod 5.0.2.0 currently installed. I cannot access the recovery mode AT ALL. I cannot flash or push a new recovery but it fully boots into Gingerbread w/o any issues. What is wrong with my phone and how do I fix it.

Try from rom manager to reinstall a previous recovery version.

That doesn't work either. It goes through the prompts but it doesn't actually reboot do the installation.
I just tried unrooting and then re - rooting but that didn't work and I think that actually wiped my phone completely. I don't even know where an SD card would get into this thing.

Is that the right name of the recovery img? Try renaming it to just recovery and see if that works.
Edit: make sure your phone is in debugging mode. And uninstall then reinstall the drivers on your computer

manually go into recovery with volume down and power flash the su.zip and u should be good to go that wat I did
Sent from my Nexus S 4G using xda premium
No suggestions have worked so far. It does not matter what the recovery image name is, whenever I try the flash it Terminal says that it cannot load "***.img" or if I try an install command it says that it cannot find "***.zip" I'm on a snow leopard iMac so I don't need drivers n such.
Let me pose the question like this, what would I do to completely restore the phone to factory condition and try to root it again? Like I said before, the bootloader says that it is unlocked but I do not have any root privileges, could not access the recovery I had before nor install a new recovery after having locked the unlocked the phone's bootloader again.

go to the link above and follow the directions for returning to stock.
find yourself a one-click root method on XDA that includes superuser, busybox, and CWM.
EDIT: Also, double check the md5 sum for the CWM .zip. use
Code:
md5 recovery-aaaaaa.img
in the terminal and make sure the output matches whatever is given on the CWM site. if they dont have one up, ask for it
NS4g one-click root app:

If you have access to fastboot, then flash a factory os. That simple.

Superwipe script wiped everything. HELP

Ok. I used a super wipe script. Now my device has nothing but the boot loader and twrp is still installed. I was on the new ota 4.2.2. I also have 4.18 boot loader. I have no os and all of my backups are gone so I can't restore anything. How can I install this from a computer and push it to my device? I really need help. I'm not brand new. But I've never been in this situation. Thanks to anyone who can help make my device operable again.

If TWRP is installed and you can boot in TWRP, try to mount the usb and copy the backup to the device. I'm not sure, but you could use adb push in the recovery, too
Otherwise just boot into bootloader, flash the stock rom, boot, root, copy the backup on the sdcard, flash TWRP, restore it

Do it like the guy above said, or just download the stock image (for your device) from here, extract everything and just run the flash-all.bat (if you are on windows). This will flash the stock rom so you should be able to boot your device again

It seems like for me downloading the stock image and running the flash all bat would be the best solution for my level of experience. I just don't know what you mean by running the flash all bat.

No need to install anything! Just download the package for your device and extract it. Now open the archive and there is a file called flash-all.bat.
Now you hold power and volume down on your nexus 7 to get into fasboot mode (the bootloader). If you are there, plug the nexus via usb in your pc.
Now just double click the flash-all.bat and it will flash the stock rom
If this won't work, because windows can't detect the device, download the Nexus 7 Toolkit, install it and open it. There's an option to install the drivers

Phone reboots into TWRP

well I have been having problems on how to do unlock my phone using a Mac, but I was finally able to unlock it and flash TWRP recovery by using mattlgroff's utility 1.20 now the I have installed TWRP recovery, every time I connect my phone to the Mac it asks me superuser permission for AdB shell I grant permission and it says "Adb shell has been granted permission" and it reboots into TWRP recovery. I even denied superuser permission but it still does the same thing. I have USB debugging on.
is this normal? because I need to transfer some files to my phone so I can Flash a Rom through TWRP. I would really appreciate your help. thanks.
here's a picture attached showing what it says as soon as I connect the phone to computer.
after that it just reboots into TWRP.

As goofball2k said, you don't need to root your device to enable USB debugging. In your case though, you can't enable it due to the broken screen.
When your screen is locked and you connect your phone to the pc, does it show the phone? If it does it will probably show no folders inside. Right?
What you need to do is unlock the bootloader, flash a custom recovery and then in the recovery you will be able to use adb pull command.
To do all that you can read efrant's guide (unlock bootloader, flash custom recovery) in this forum, or you can use a toolkit like this guy in your same situation: http://forum.xda-developers.com/showthread.php?t=2177440
I would recommend efrant's guide as it teaches you the basics on how to use adb and fastboot to flash anything you like.

Unlocking his bootloader will wipe the device though. He's SOL unless it's already unlocked.

True, but I think that with "boot unlocker" you can unlock the bootloader without wipe
Sent from my Nexus 4 using xda app-developers app
Another solution would be to make a backup image of the entire phone memory (see the bootloader unlock sticky thread), but he needs to set a password for the desktop backup first.

It needs root to work and he can't unlock his device to use an app even if he had root.
