I have a Nook Tablet, 16GB model, that I received during the 2011 holiday. This summer, about 4 months ago, it stopped turning on.
I have flashed it with CM7 Alpha from CelticWebSolutions, but that was at least a month before it stopped working. CM7 ran fine while it was working. There is no physical damage to the device. The Tablet does not even get warm when plugged in and the screen does not turn on. Windows does make a noise when the device is plugged in but nothing is recognized.
I am not sure what other information I can give. I would have posted this immediately to the forums if I was not so preoccupied this summer. All help and advice is greatly appreciated.
