Ok so my problem is i got a hacked psp given to me and i didn't want it to be hacked so i started downgrading to 1.5 but while doing so my psp battery died and now i have no firmware at all. all that happens now is the green led for power stays on and the screen stays blank... I can't turn it off or go into recovery mode. What should i do. Btw i can't buy a pandora battery just incase you think it may help. I can take the battery out and as soon as i put it back in the green light comes on. Any suggestions? Or Ideas?
