Is it possible to Upgrade 3.71 M33-3. to 4.01 M33-2 without

Is it possible to Upgrade 3.71 M33-3. to 4.01 M33-2 without pandora battery? I have a chance to get a psp with 3.71 but i want 4.01 on it and i dont have the battery.

the psp you're getting has 3.71 m33 firmware on it or it's the regular sony 3.71 firmware?

if it already has m33, then you wont need pandora, if its sony firmware then you will need pandora

The psp has the 3.71 m33 but the person i got it from updated it to the lastest 4.01 m33-2 for me. Now i will just look around and figure out how to put iso's and emulators on it and i should be good. Thanks for the reply.

there should be a tutorial in our tutorial section on how to add iso/cso files and homebrew called the ultimate starters guide
