My friend was having some trouble with his psp and he wanted CFW so I told him I would take it home and fix it up for him. I used a MMS and Pandora battery to get him to 1.5 and then I updated it to 3.52 4 m33 and everything was working fine. Now, when you try to turn his psp on the green light comes on for a few seconds and then shuts off. Sometimes I can get it to go to the recovery screen and that comes up fine but once I exit it the screen goes black and the light turns off. I tried to re-Pandora it but the process never finishes, the psp just turns off. Any suggestions?
