      Root isn’t must but some time it needed to install CWM recovery. We interpreted what developer said on development page. If you have Android 4.1.2 Jelly Bean then technically you have Jelly Bean bootloader and can install this ROM if you have the said device model.

          @google-f08a58ed469599184bce1ab43e4e1925:disqus Xoom Wi-Fi is MZ604 and Xoom 3G is MZ601. This is for Xoom Wi-Fi.
