Nexus Root Toolkit is the easiest way to Unlock, Root, Relock, Unroot, or Unbrick your device. It also has several other functions such as backing up your device. The list of supported devices is long. This Tool supports Galaxy Nexus, Nexus S, Nexus 4, Nexus 7, and Nexus 10 devices. The best part of this Toolkit is that it brings all the needed files to you. You don't have to scour the web looking for Root files, recovery images, or stock images, simply click a button and viola the files are downloaded for your device. The latest update brings full support for the latest version of Android 4.2.2. Some new features in the Advanced Utilities include logcat/bugreport generation interface, adb sideload button, and restore stock kernel script. Lots more is included in this update.

I've seen this application transform from a fledgling collection of scripts, to an all out backup, rooting and flashing behemoth. Congratulations on the new version and device support.:rockon:
