Ok, my problem is in this way: I own 2 PSP: 1x2004 and 1x3004 I've unfortunately full-bricked the 2004 one and can't do a thing. I don't want to use a pandora battery (the hardware modified one). I've already read http://forums.exophase.com/showthread.php?t=3780 but this couldn't help me. What I've tried: I've put a 3.6V - 1200 mAh in the 3004(modded) and used Hellcat's Pandora Installer for 3.XX Rev 3b and made the battery pandora. I've had already a magic memory stick so I've put them together in the 2004 PSP. I've hold the R button while turning it on but no succes. Can someone help me ? Thanks.
