OK little preface, when I got my N7 I updated to 4.2.1, unlocked the boot loader and rooted with no issues. I found the zip for the 4.2 tablet ui and flashed it though TWRP. For whatever reason that soft bricked my N7. I completely spaced making a backup so I was stuck. I was able to flash the stock 4.2.1 firmware and got it back up and running. now I am trying to reroot my tablet but it's not working. I've tried flashing the superuser zip through recovery and also tried using the toolkit to push the needed files and nothing has worked so I'm at a loss

Xda is not your personal tech support. That being said, flash stock and fastboot OEM lock.

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.

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
Sent from my Nexus 7 using xda app-developers app
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.

Doesn't this void the warranty though? I know it did when i rooted my phone.

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.
Does anyone have the flashable grouper OTA zip? I know they are already rooted 4.3 ROMs but I rather use the OTA zip.
Thanks in advance.

Download the factory image from this official link and flash it on your Nexus. Don't forget to backup your data first as flashing it will erase your device completely.

Also, somebody has made a version flashable through custom recovery in this section
Thanks guys. I'm going to get on it now.

could you tell me the steps that you follow to install the factory image?
Easiest is to use Wugfresh's Nexus Tool Kit.
Otherwise if you're rooted with custom recovery, you can find a flashable version in one of the Dev threads.
Follow the instructions in the OP of either method and all will go well.
Here you go, follow this guide.
Hello! I updated my nexus 4 to 4.3 with the OTA, but why do so many people have trouble updating their N4 to 4.3 when they are running a custom rom?
U can easily flash 4.3 builds through CWM or TWRP. Or is there a difference between flashing through recovery and flashing through fastboot?

Flashing through fastboot means doing it thru your PC with commands on the CMD and i think it uses different files ( I'm not so sure about that)

Yeah I know but why does everyone want to flash it through fastboot if you can easily flash through recovery?

At least to me, i tried flashing thru custom recovery and it gave me an error every time so had to flash the image thru fastboot. Its (i think) the easiest way if you don't want to find youself having many problems.
Hello wonderful XDA Peoples. I am planning on returning my Nexus 4 in the near future as part of T-Mobile Jump. I'm currently on a stock ROM; but unlocked with CWM recovery installed.
To return to stock, would I need to fastboot the entire stalk image (via flash all.bat) or would I just need to flash the stock recovery image, then relock the boot loader? Thanks guys! Keep up the absolutely spectacular work.
Sent from my Nexus 4 using xda app-developers app
You could just flash the recovery.img and then re-lock it

on the nexus 4 rom,kernel .... index there is a stock recovery flasher, if you dont wanna use the pc
if you have root you can lock bootloader via an app
or else just via pc.

With n-cry toolkit is posbly.
