I just rooted my nook color today after ordering a 8gb sd card a week ago. At first it was working fine but then after a hour or so it froze so i turned it off and tried to turn it back on. The problem is when the CM7 logo pops up it starts, freezes, and keeps repeating itself. I have no problem getting back to my regular nook (im on it now) but i can't get back into the rooted form. What should I do? Please help!
