NOTE: THIS IS FOR THE GSM VERSION ONLY. DO NOT ATTEMPT THIS ON THE VERIZON VERSION.
PROCEED AT YOUR OWN RISK. DRAGONS AHEAD ETC.
This is pretty easy to do if you're familiar with fastboot, etc., but you'll need an unlocked bootloader before you can do this.
First, grab the factory images and extract them into whichever directory you have fastboot.
Get the images here: Factory Images for Nexus Devices - Google Support for Nexus Phones and Flagship Devices - Google Code
Then you'll want to reboot into fastboot mode (shut down, then hold vol. up + vol. dn + power), open up an (administrator) command prompt in your fastboot directory and run the following:
(if your fastboot exe is called fastboot-windows, use that in the commands below instead)
ONCE AGAIN, THIS IS FOR THE UNLOCKED INTERNATIONAL VERSION ONLY, NOT THE VERZION LTE MODEL.
After this completes, you phone should reboot with 4.0.2.
The difference here is that we didn't tell fastboot to wipe the user data and cache in the final step, so all your stuff will be there once the phone reboots.
