Android 4.2.1 Update is barely out the door, bringing with it all the bug fixes and patches, along with the much-needed and missing “December” from the People app. A new version of Android always means one thing in particular – wait time for a new root method or package for the latest update. Well, thanks to the wonderful developer community that we have all come to trust and love, wait is over, or rather, got over long before you knew it, because Android 4.2.1 is also rootable on all the devices – Nexus 4, Nexus 7, Nexus 10 and Galaxy Nexus – just like its predecessor was. The method has no bells and whistles attached to it, either, and involves flashing a custom recovery and pushing the SU binaries to your device. We’ll guide you how just past the jump.
