Are you a Galaxy Nexus (yakju) user and waiting for the 4.2 OTA update while the same has been pushed for Takju variant... please follow below to convert from yakju to takju (stock) without loosing your data/apps: (assuming you know adb & fastboot and have set them up on your computer. Also assuming that bootloader is unlocked) [Please read before you implement]
1. Download the 4.2 factory images for Takju from http://goo.gl/UMbmS
2. Extract files using 7-zip on Windows (you need to extract twice and will get the files as: bootloader-xxx.img; radio-xxx.img and image-xxx.zip)
3. Copy these files to the location android-sdk/platform-tools/ (if you have the android-sdk installed or to the location where adb & fastboot is)
4. Plug in your Galaxy Nexus (ensure Debug option is enabled under Developer Settings
5. Follow these commands:
a. adb reboot bootloader
b. fastboot flash bootloader bootloader-xxx.img
c. fastboot reboot-bootloader
d. fastboot flash radio radio-xxx.img
e. fastboot reboot-bootloader
f. fastboot update image-xxx.zip
This would update your Galaxy Nexus from Stock 4.1.2 (yakju) to Stock 4.2 (takju) without losing any data/apps
Note:
1. If you using Windows follow the video tutorial to setup adb and fastboot http://goo.gl/jGcic
2. If you are on Mac, use ./ before the commands for execution
Note 2: With this method you don't need to remove the userdata.img as the command "fastboot update image-xxx.zip" does not touch the userdata on your device.
*Disclaimer: I have followed the above to the T and moved from Stock 4.1.2 (yakju) to Stock 4.2 (takju) with Unlocked Bootloader, but you follow these at your own risk.
Hit Thanks, if this has helped you.
