after 2 months hard work ill release a first alpha.
it will restore only a part of the FW.
extremly buggy, but a first step:
-create folder "restore"
- put FW 1.5 and my .pbp intp
-psp will reboot
-enjoy FW 1.50 (buggy)
this wasnt done by me just some guy named 12step on psphacks.net try it out u have nothing to lose on a bricked psp and tell me the results
