I have a PSP fat that I have replaced with a newer PSP. I would like to use the fat as a homebrew device, so I am no longer worried about being able to play my UMD or downloaded games on. I have been away from here for a while, but I thought that 1.00 was the way to go, but perhaps it is 1.50 now. Anyways, I have CFW 5.50 GEN-D and would like to go back to whichever is the most compatible with most of the homebrew out there, but I am having trouble finding instructions on what to do. I am not sure if I need another CFW and then I go back or what.
I really appreciate the help!
