Root I Screwed Something up! Please Help!

[wysts43]

Time to call in the big guns... a.k.a. my friends at Phandroid! So, i was playing around with ROMToolBox and attempting to change some of the system icons (the wifi icon to be exact). Well, my Nexus7 DID NOT like this. By the way, I am unlocked/rooted with CWM Recovery, SU, etc.

I am not new to this rooting game, but I am stuck this time around. I am able to get back into Recovery and into CWM, but here's the thing, I am a dipshit and forgot to have a stock backup.... so, i have no past nandroid to reflash.

Now, i know i can get the factory image and put it back to stock (I get it here, right?: https://developers.google.com/android/nexus/images). A couple questions.

The factory image file comes as a .TAR. I was able to get a .zip file out of the TAR file, but there were also three other files:

bootloader-grouper-3.34.img,
flash-base.sh,
flash-all.sh

Do i need any of those files, or just the zip?

Also, how the heck do i get the zip file onto my Nexus7? If anyone has detailed instructions on how to do this, i'd appreciate it.

Third, do i have any other options? You guys are all smarter then me, so please save me!

OK... nevermind... maybe. I realized i had an AOKP zip on my sdcard that i was able to flash and get into my nexus7. Basically back to stock, but oh well i suppose. Nandroid lesson learned.

I guess my questions about the factory image still stand though. I'm curious now.

Hi wysts. The easiest way to get back to stock is use the Nexus Root Kit. Just tell it to download and install the stock for you.


To answer your question about what to do with the file you download; this info came from [Guide] Returning to Stock and/or Unbricking your device at XDA using ADB and Fastboot. Note: the image file name in this command, fastboot -w update image-nakasi-jrn84d.zip, will change depending on what stock file is current you downloaded. Right now it is image-nakasi-jro03d.


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

1) Download the factory image for the Nexus 7 here

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

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

fastboot flash bootloader bootloader-grouper-3.34.img

5) Next type

fastboot reboot-bootloader

6) Now type

fastboot -w update image-nakasi-jrn84d.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

fastboot oem lock

8) If your tablet hasn't already rebooted automatically, 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 if you so desire.
