After I’ve got my new nook (NooKcolor) just about one month, I tried to hack it as android tablet and I found very easy tactic that they call “Root” from nookdevs.com
What my goal after do that ?!!
** upgrade firmware to version 1.0.1 before Root
and then just follow nookdevs step by step
Only negative that I found after Root is “I’m playing more than reading”
