I'm having a strange problem that i hope someone can help with. I can get froyo installed to internal memory fine. it runs fine until i put an sd card in. If i put an sd card in it sees it and mounts it fine but if i turn off the nook for any reason it will not turn back on. If i turn the nook off before i put the card in it will restart fine. But once i put the card in the first time once i turn it off it will no longer start and i have to do a complete restore and start over again. I tried taking the the card out before i turn it off but that produced the same results. So basically the first time it mounts the sd card i can no longer turn the nook off if i want it to start again. Any suggestion besides just never turning it off.
