If you get your Nexus device into a lick of trouble and want to reset it to factory settings, Google has updated its images to the latest version of its mobile OS, Android 4.2.1. Coming a week or so after Android 4.2 was released to AOSP, the factory images don’t change much other than re-adding December to the People app.
While the Nexus 10 is stuck on Android 4.2 for now (there was a problem with the original image), you can download images for the Nexus 4, Nexus 7 and yakju/takju Galaxy Nexus.
Have it your way over at Google Developers.
