Hardware mod PSP cannot upgrade to 3.71 m33?? I have a hardware mod fat PSP. I tried to upgrade from 3.52 m33-4 to 3.71 m33. I ran the 3.71 m33 update. Everything went ok until the "official" look update start. It gave me a error message and the program exit. Back to xmb. i checked version, 3.52 m33-4. didn't update. I shut off the psp and never back on again. now it's black screen and green light.
