Possible to unroot N7? - Nexus 7 Q&A, Help & Troubleshooting

Hello-
I was wondering if its possible to unroot my N7 and return to stock if I decide to root it. Also, if there is a system update , what happens? Do I lose root and must reroot it or do I keep root?
Thanks,
wws

You can easily unroot a nexus device with using google factory images and flash them. then you are 100% stock and unroot.
normally update via ota is not possible while in root or if, it may removed after doing it.

Or use the wugs Nexus 7 root toolkit. There's an option to unroot and to flash stock.

(Q) system update downloaded- safe to do?

Hello guys,
I got my n10 today, rooted using marks toolkit.
Now the notification says "system update downloaded" and press to restart and install...
Is there an update or is my tablet trying to restore the original bootloader, and will updating unroot my phone?
Thanks,
Mark.

The OTA is normal. It has nothing to do with root.
I'm not sure if you'll lose root. I don't remember the order of what I did. If you lose it, just re-root. Or you can download Voodoo OTA Root Keeper, which has worked for me in the past.

Yes, you will lose root but you will remain unlocked... in fact, it is a good idea to unroot before installing OTA updates... being a Nexus device, this can easily be re-rooted....
Thank you guys!
I will do it then... Cheers, Mark

Backup and Root

I am currently using an unrooted, completely stock nexus 7 running stock 4.2 jelly bean. My questions are: how can I create a backup of my tablet before I unlock and root? And what is the best/ easiest way to root my tablet without any issues.
Thanks in advance!

I used wugs root toolkit in the dev section. It has an option to backup before rooting.

[Q] upgrade or root? which is first

i had nexus7 32gb with android 4.1.1 / kernel 3.1.10 (without any modification, stock rom, without root, without unlock etc.)
i want to upgrade to latest android,
which way for upgrade is proper for my device?
firstly upgrade than root
or
firstly root than upgrade
upgrade then root. If you rooted first you would lose root with the upgrade and have to root again. Just upgrade first then root:good:
I would root first and update after that. Use the OTA rootkeeper app to keep root. (A lot of people had trouble rooting their device on 4.2)

Downgrade to 4.1.2 possible for nonrooted ?

Hi everyone I was just wondering if its possible to downgrade my nexus from 4.2.1 to 4.1.2 if I'm not rooted. I'm currently not interested in rooting my device so is there a way to do it without rooting/unlocking?

I can't flash things because I'm unrooted. So I don't think this method will work. Correct me if I'm wrong.

Anyone know?

I do not know for sure but I quite doubt it.
I am curious as to why you want to though. Not that there's anything wrong with wanting to downgrade, of course.
Have you tried one the took kits available? Check around in the Nexus 7 original development section. Look for Wuggs.

I looked at his toolkit but it basically says that I have to root in order to even use the toolkit so is there a way to downgrade without having to go through that rooting process? For now, I don't want to root my nexus

Don't try to root it you'll only manage unlocking the boot loader then when you try and root it it will get stuck in fast boot mode I tried about every rooting program but it could be because my Comp is running windows xp lol

It's so easy to just reflash stock and relock the bootloader that you really have nothing to worry about. If you want unrooted stock 4.1.2 just unlock the bootloader, then flash the stock image of 4.1.2, then relock the bootloader after. It's a really simple process.

If i'm not mistaken, as long as you flash back to 4.2.1(which is the os it came with when u got it out of the box), and then re-lock the bootloader, unroot, then your warranty wont be voided mate. hope I helped.

Yeah, I've done this plenty of times with my Nexus 7 and even the Verizon Galaxy Nexus. As long as you're on a stock image with a locked bootloader, they won't give you any trouble or claim you voided your warranty, as there's really no way to tell. I've gotten into the habit of unlocking and rooting my device as soon as I get it, and if I find a problem I just revert back to a stock image, relock the bootloader, then send it back in. I have yet to have a single issue.

You don't need to worry about saving your stock image. The person above you is talking about saving the stock image to return to after flashing a custom ROM.
There is no way to revert back to 4.1.2 without root access. Doing a factory reset, about the only thing you can do without root, will only return you back to stock 4.2.1
My advice just stay on 4.2.1 whatever your issue is with it.
Otherwise use a toolkit. You will need a PC and the 4.1.2 image. Wugfresh has a website. I would start there.

I actually was just referring to the stock images you can get directly from Google or from goo.im. It's easy enough to just use the 4.2.1 stock image from Google to just restore back to how it shipped, and then relock the bootloader.

Completely agree with this... I have, on several occasions, reflashed stock, switching between 4.1.2 and 4.2.1 - (for me, it was more of an exercise in learning about fastboot and adb... and making sure I had TRIED AND TESTED factory images on my laptop as contingencies should anything go wrong when I came to start flashing custom ROMs).
-----
You don't need root to flash a factory image... everything is done with fastboot; with the Nexus 7 in FASTBOOT/BOOTLOADER mode (from complete shutdown, press and hold Volume Down button... whilst holding, press the Power Button).
(Root is meaningless anyway, here in FASTBOOT/BOOTLOADER mode, since /dev/block/mmcblk0p3, the SYSTEM partition, hasn't even been mounted yet - so no SU binary available... whether or not it exists, it's sort of irrelevant).
- here, for example, is the flash-all script from 4.1.2 (nakasi-jzo54k)... (Nexus 7, WiFi model only).
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.41.img
fastboot reboot bootloader
sleep 10
fastboot -w update image-nakasi-jzo54k.zip
After running this script (flash-all.bat if in Windows, or flash-all.sh if an Apple user) you can optionally choose to lock the bootloader with... (if you're concerned about warranty issues).
Code:
fastboot oem lock
-----
If it was the case you needed root to run...
Code:
fastboot flash [partition to be flashed] [IMG file to flash]
...you wouldn't be able to flash a CUSTOM RECOVERY like CWM or TWRP... and thus, you wouldn't be able to flash Chainfire's UPDATE-SuperSU-v1.00.zip (http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip) in order to gain root in the first place!... (you see the paradox!).
Rgrds,
Ged.

Its like supersu pro or whatever.

Just flash recovery and then download the supersu zip. Flash the supersu and you are rooted

I used CWM to install the original zip. It prompted me before rebooting if I want to keep root/recovery and to fix it.
I used this thread to reroot using adb...

I used the Nexus 4 1.3 toolkit with updated files
As a precaution I backed up my folders and make a Titanium backup. Technically re-rooting will not WIPE phone like it did first time I purchased it.
I could have installed CWM but prefer to keep this phone stock, considering its as pure as it will ever be and want the OTA updates.
But there are so many options to get ROOT lots of options. Love it so far.
You can use cwm for flashing the ota to avoid the hassle of using adb sideload. You can choose stock recovery after flashing the su zip. Just use the cwm to flash ota and su. Just my 2 cents
Sent from my Nexus 4 using xda app-developers app
I just paid the £1.95 for Su Pro, which keeps root over OTA updates. Worth the money IMHO, I have wasted more time that that in faffing around each time.
Just rooting it like you did first time will work.

Just root again, OTA will make your phone rooted again!!!
Wow. Thanks everyone. I am gonna try a few these. I had no idea su pro kept root. Only had i known
I learn.
After you reroot, get OTA Root Keeper from the Play Store so you can restore root in the future after an OTA
ok... so i figured out an easy way... i used nexus toolkit to root in the first place and then saw this on wug's website... followed the direction and got root back... Thanks everyone for your help
also, its not clear below, but these files are replaced on your computer under C:\Program Files\WugFresh Development\data
"Yes, I am aware that this isn’t working on 4.2.2 right now. This will be fixed in v1.6.3 which will be released ASAP (within a few days or sooner if possible). As a temporary fix you can replace the old adb/fastboot/dll files in the toolkits /data directory with the new ones: new_adb_and_fastboot.zip just download that zip and extract/unzip its contents into the toolkits /data directory and agree to overwrite those files, then proceed to use “Any Build” mode to perform subsequent operations like rooting. Again, this is just a temporary fix for those who are impatient."
