I just bought a used PSP with the 6.60 pro b9 custom firmware installed. Everything was alright until a couple of days ago I turned it off accidentally, and when I wanted to boot again the cfw, it would just show the white psp screen and then it would turn off completely. I tried turning it on again and there were no problems, I just can't get the custom firmware to work again. Could you help me here, please?
