So here's the case so far: I bought a PSP 1004 with semi-brick on it. Tried all kinds of repairs, but none of them worked. Worked with Pandora set, Hellcat and ELF. I'm using original Sony memorycard and battery. I also got a second PSP 1004, which I used to make a pandora set. 1.50 -> corrupted icons on xmb, reads from memorycard and umd but programs freezes on PSP logo 3.71 -> Playstation logo and sound on start, but freezes before xmb 3.80 -> black screen 3.90 -> black screen 5.00 -> black screen 5.50 -> black screen Tried with OFW and CFW -> same problems. Currently has DCv8 5.50GEN. It goes to the recovery menu, but when I try to load anything, it freezes. I can upgrade/downgrade using pandora set and elf (only with elf and Pandora I can start programs). Currently if I try to do anything, everything ends up frozen. So I really need help with this project. Sorry if this doesn't make sense, but I'll try my best to answer questions ----------------------- Edit: DCv-versions 5 to 8 doesn't work (black screen), only older versions work.
