[Guide] How to install Android 4.4.2 based OmniROM 4.4.2 on your Motorola Xoom

The Motorola Xoom was released back in 2011 as a pure Android tablet and even though Motorola has since stopped supporting the device with updates, it remains a top device for developers. Because of this the XDA developer community has released an Android 4.4.2 KitKat-based OmniRom build which will bring Android 4.4 KitKat to the rooted Motorola Xoom.

If you are interested in trying out Android 4.4.2 on your Xoom, please check out our following guide on how to install Android 4.4.2 based OmniROM 4.4.2 on your Motorola Xoom
