I upgraded to the 3.40 OE-A with no problems, then today I was playing a game, and it shut off. After I reboot all i get is a black screen. I went into recovery and downgraded to 1.5 again, then upgraded back to 3.40. I then went back into recovery and if I chose the configuration menu, all I get is a blank blue window with no options and no way of going back. I have to reboot again. It seems to work for now even though i can't get into the configuration menu. Any Ideas on what happened?
