well i was in the middle of the new update and my psp fell and the battery popped out from its cover so it shut down in the middle of the update.. and i know nothing is wrong with the screen or the battery cause the light turns on green and after a few seconds it will shut down by itself and the screen will just stay black... ive looked everywhere else and this is my last hope without replaceing it wich is very expensive.. :upset: PLZ HELP ME!!!
