Post [Guide] Returning to Stock and/or Unbricking your device Updated for Android 4.3!!!

First of all, I am in no way responsible for anything you do to your tablet period.

I have seen a couple of people asking how to return the Nexus 7 to stock after it has been unlocked, rooted and so on, so I figured I would write a quick guide as its super easy to do. Also, please make sure you make a backup of anything you don't want to lose. This is important.

Before you begin, please make sure you have ADB and Fastboot drivers installed and working.

1) Download the factory image for the Nexus 7 at https://dl.google.com/dl/android/aos...y-d341d356.tgz

2) Extract the factory image into the same directory as your ADB and Fastboot executibles (e.g. "\android-sdk\platform-tools")

3) Plug in your device. If you are booted into Android, open a command prompt to your ADB and Fastboot directory, then type
Code:
adb reboot bootloader
If your device is powered off, press and hold both volume keys and the power button simultaneously. After holding all three buttons for a couple of seconds, your bootloader should launch. This should reboot you into the bootloader.

4) Type
Code:
fastboot flash bootloader bootloader-grouper-4.23.img
5) Next type
Code:
fastboot reboot-bootloader
6) Now type
Code:
fastboot -w update image-nakasi-jwr66v.zip
7) Optional: If you would like to relock your bootloader for warranty or security purpouses, make sure you are in your bootloader screen again and type

Code:
fastboot oem lock
8) If your tablet hasn't already rebooted automatically, type
Code:
fastboot reboot
That should do it. You should now be on stock Android 4.3 and ready to send in your tablet for warranty purposes if you so desire.

Also, thank you to XDA user Shano56 for the formatting help on this post.

1) Make sure you have your ADB and Fastboot drivers installed and working.

2) Download the factory image for the Nexus 7 here

3) Unzip the factory image into the same directory as your Adb and Fastboot drivers.

4) Plug in your device. With the device on the home screen, type "ADB reboot bootloader" or if your device is off, press and hold both volume keys and press the power button. After holding all three buttons for a couple of seconds, your bootloader should launch.

5) This should reboot you into the bootloader. Now type "fastboot flash bootloader bootloader-grouper-3.34.img"

6) Next type "fastboot reboot-bootloader"

7) Now type "fastboot -w update image-nakasi-jrn84d.zip"

8) Optional: If you would like to relock your bootloader for warranty purposes, make sure you are in your bootloader screen again and type "fastboot oem lock"

9) I don't remember if the tablet automatically reboots at this point but if it doesn't just type "fastboot reboot"

That should do it. You should now be on stock Android 4.1 and ready to send in your tablet for warranty purposes.

You should change the title to [Guide] How to return to Stock / Unbrick your Nexus 7

Helps out those getting bootloops or softbricks from geting root access in certain ways or messing with the build.prop

Not a bad idea. Done and done. Also, I have proofread it several times over to ensure it is correct but would you mind making sure that all of the commands were typed correctly. My eyes are going crosseyed over here.

Nice guide man, I changed the format a little to make it easier to read. Use it if you want, won't be offended if you don't.

If you want to use it and are too lazy to quote my post - http://pastie.org/pastes/4279753/text

The commands look good to me however I've never used "fastboot -w update" so can't say for that

Assuming you have a nandroid, can you boot into the bootloader, and simply ADB reboot recovery? Or does that bug prevent you from even doing that?

In some cases due to the CWM not being official it cause bootloops by going to recovery in the bootloader.
