and 3.71 Update file: 3.71 update file
MAKE SURE YOU KERNEL IS SET TO 3.52
you can do this in recovery mode
start the psp up whilst holding the R shoulder button down,go to configuration find the option for kernel and make sure it's on 3.52
Installation instructions:
First method for both psp, the prefered when possible:
Requeriments: a fat psp slim with 3.52 M33-3 or 3.52 M33-4. Previous versions of M33 won't work,
due to a bug that affects them and OE; or a psp slim with 3.60 M33.
- Copy the UPDATE directory into /PSP/GAME/UPDATE and copy the EBOOT.PBP of the 3.71 Sony updater
there but with name "371.PBP". Note: the program will not even show if you copy it to a different folder than that.
- If you are in the fat psp, make sure you have configured the psp to run the game folder in the 3.XX kernel.
- Execute the program, it requires 78% of battery. If you have idstorage corrupted due to a downgrader, the program
will ask you to correct it automatically so the update can continue.
- Press X, and the Sony updater will begin. Sit and enjoy while Sony code installs 3.71 M33
- When finished, the updater will ask you to reboot (pressing X or O). DO IT. Do not skip this step
shutting down the psp by yourself, or you'll end with a brick.
- You should be now in 3.71 M33
