I used the pandora battery on my psp and it downgraded just fine but when i plugged in the ac adapter it won't take a charge. It was charging just fine right before I made the battery. I bought a PSP battery charger and charged the battery and the psp works just fine that way but if i take the battery out and try and use just the AC adapter that came with the PSP it doesnt do anything at all. Can someone please help me? I just down graded my uncles PSP and his just did the same thing.
