[HOW TO] Restore Galaxy Nexus to Stock V2

---

This is a tutorial on how to return your Galaxy Nexus to stock if needed. This method uses the official images from Google

I am not to be held responsible if anything goes wrong when attempting this. This includes bricking your phone, flashing a bad image, causing WW3 etc. I am also not responsible for any files in this tutorial. They were all provided by other people.

There may be inaccuracies in this post that may lead to various things such as bricked devices so be warned. Let someone check it over first! If you see anything wrong, let me know and I will edit it!


What you need

• Samsung Galaxy Nexus GSM Version
• All the usual fastboot & ADB drivers etc
• Fastboot
• Official Google Image

Google Images
https://developers.google.com/android/nexus/images

Fastboot
DOWNLOAD

1) Take a Nandroid Backup if you have CWM installed

2) Extract the content of the Google Image

3) Copy the contents of the Fastboot download to the same folder as where you extract the Google Image too.

4) Boot your phone into the Bootloader mode

5) Open up Command Prompt or Terminal, navigate to the folder you've extracted it all too and enter the following commands waiting for each to finish
Windows
fastboot-windows flash bootloader bootloader-maguro-primekk15.img
fastboot-windows reboot-bootloader
fastboot-windows flash radio radio-maguro-i9250xxkk6.img
fastboot-windows reboot-bootloader
fastboot-windows -w update image-yakju-icl53f.zip

Linux
./fastboot-linux flash bootloader bootloader-maguro-primekk15.img
./fastboot-linux reboot-bootloader
./fastboot-linux flash radio radio-maguro-i9250xxkk6.img
./fastboot-linux reboot-bootloader
./fastboot-linux -w update image-yakju-icl53f.zip

OSX
./fastboot-mac flash bootloader bootloader-maguro-primekk15.img
./fastboot-mac reboot-bootloader
./fastboot-mac flash radio radio-maguro-i9250xxkk6.img
./fastboot-mac reboot-bootloader
./fastboot-mac -w update image-yakju-icl53f.zip

6) The last step is to lock the bootloader. Restart the phone into the bootloader

7) Open CMD in the location of Superboot and type:
fastboot-windows oem lock

Anyone other than the OP try this yet? If so, what state were you starting from (cwm installed, which custom rom etc) and did it work? did you need to do anything differently?

It works, can confirm!!

1. copy the extracted rom folder to clockworkmod\backup\maguro_4.0.1 on your internal storage
2. boot in too cwm
3. (what i do) in mount and storage menu, format system/data/cache
4. install super wipe lite zip file
5. restore the maguro_4.0.1 rom

phone boot up, everything fine, first run wizard start..

6. reboot to fastboot
7. flash the stock recovery "fastboot flash recovery recover.img"
8. boot in to recovery to test
9. reboot the phone

i didnt lock the bootloader while i will only root the device and other things let on stock.

i came from unlocked bootloader, clockworkmod recovery and android revolution hd rom..

Brilliant news.

I've updated the tutorial to include the latest updates

so you cant just do a erase all content and setting like you can on the iphone?

Even on a jailbroken iPhone, when you do a factory reset you get all your settings reset but the phone is still jailbroken.

Same thing applies with Android. You need to flash the stock files to get back to stock.

@evostance

Another possibility (as yours relies on having access to a backup/nandroid as well as somehow being able to access the SDCARD partition) which some people may not have

I tried that and it trashed my phone, so I had to restore to the zip above and all way fixed.
I think Peter might have changed his files now but not sure

guys have one problem, after i sucessdully restore the stock rom over the method i wrote i try it over fastboot with the original oem files from peter, erase system and user partition over fastboot and flash it again with the files on his site.. everything seems to work, and i finish with the setup from my device bit then i see in google account my calendar didnt sync, there is no entry for it.. i try to delete the account and recreate it but without success.. anybody here a idea what can ne the problem?? any suggestions how to fix that?? i dont want make the whole proceess over recovery, i like this method more while they are really empty images and not a nandroid backup..

many thanks!!
