Answer 1

so you're saying you're having trouble upgrading from 3.71 m33-4 to 4.01 m33?

then download this: http://dl.qj.net/PSP-CFW-4.01-M33-PSP/pg...

and this: http://downloads.pspspot.net/firmware/70...

after you unpack the first file, you'll need to copy the UPDATE folder into PSP/GAME, then you'll need to unpack the 2nd thing you downloaded, in there somewhere you should find something that says something like eboot.pbp, you'll need to rename that to 401.pbp and copy it into the root of your memory stick (for example when i put my psp in usb mode it's in the E: drive, e is the root).

then just get out of usb mode and go to the game folder on your psp and run it, and you should be good to go.

good luck! :)
