i have a question. I made my pandora's battery and downgraded my 3.52 psp. now its running custom firmware. (WOO HOO!!!) but i think my pandora's battery is messed up now, cause i put it in my psp and turned it on. then the screen just stays black and the power, the wlan and the memory card light all flash, then my psp turns off. so how do i change the battery back to normal???
