I had autonooter 3.0 runnning just fine and I had installed clockwork recovery and backed it up with that and then rebooted the nook color. Once it shut off, nothing happened. It didn't turn back on. When I connect it to my computer, it says that windows does not recognize the device. The plug at the bottom of the nook is orange. I don't know if there is a sequence of buttons that I need to press or what, but it is not booting at all. No boot screen, no nothing. I do have a 16gb card available if needed. Please help. Thanks.
