So i have a psp from a friend (not officially mine), anyways it doesn't boot (black screen when i turn it on) but does boot into gen recovery menu. I have tried to use hellcat's recovery flasher to try and reflash the firmware, but the memory stick slot doesn't seem to work (card doesn't click in, psp doesn't read memory stick when i use my finger to keep it in there). So anyways, any ideas on what i could do?
