I am currently running a PHAT PSP with 4.01 M33 firmware, upgraded from 3.52 M33, and this firmware has completely ruined my PSP's homebrew capabilities.
Whenever I go onto Games, it says corrupted data. And there is nothing I have found with google search. Where it usually gives me all my Apps, like PSPTube and stuff, it just turned them all into "Corrupted Data" no matter what i have tried.
I have tried updating, corrupted, I have tried restoring, "Cannot be Started", I have tried almost everything.
Can anyone help?
