Well. I have a psp that im gonna have to fix in the next few days, and it has a problem i never really heard of. The psp had a really low battery when it got started to update, and like halfway through the battery died (my friend let another friend use it. wasnt good idea lol.) anyway. so from what i am hearing (havnt gotten yet) is that it wont start up when turned on, stays black? any ideas as too how to fix this? can go and update the firmware since it cant be hooked up to usb and all that. maybe a pandora battery?
