Haven't been here in ages, and I havent kept up with psp firmware news,
Now I'm back and need some help. Anyways I have a 3.52 M33-4 fm phat psp,
that I want back to 1.50 again. I have the 1.50 firmware but, I've forgotten how
to restore in recovery, Do I rename it Update.pbp? or keep it eboot.pbp
Or if someone could show me a link to a recovery guide, I'd appreciate it.
