The PSP FW 5.50 roadblock: can't be decrypted yet, TIFF incompatibility, standby bug.
ok, excuse my lack ofunderstanding, but can't any psp running CFW be downgraded from current FW update? i mean why does he just ask if the "Fat" psp can be downgraded.... could my 2001 slim (runnng 5.00 M33-6) be downgraded as well?
