hello
i recently changed my firmware 5.00 m33-6 and had no problem with it. I hard modded my own battery and knew that it wouldnt work any more so bought a new one. The new battery is an official 3.6v battery and when i put it in it will not turn on. If i have the ac adapter in it will but once i unplug it it turns off. And when i check what that battery charge it says that the power source is external. I have tried putting in my brothers working psp battery and still no luck. I have no idea what it is that is causing this and any help would be appreciated. Oh and its an original psp 1001 model.
Thanks.
