    3.52 M33 HERE

    3.52 M33-4 HERE

    3.52 firmware HERE

    1.50 firmware HERE

    Download the 3.52 M33 CFW linked above. Extract the file.

    Download both the 1.50 and 3.52 firmware. You need to re-name the 3.52 firmware to 352.PBP the 1.50 firmware to 150.PBP. Then add them to the M33CREATOR folder.

    Now copy the M33CREATOR folder to the PSP Memory Stick directory of ms0:/PSP/GAME folder.

    Now go to game Menu Memory Stick and run the M33CREATOR.

    After you run the M33CREATOR it should reboot back to the XMB. It should have created a 3.52 M33 update which you need to select in the Game Menu Memory Stick.

    It will flash the files to the PSP and you should be at 3.52 M33 firmware. If it is then format your MS.

    Now extract the 3.52 M33-4 update.

    Drag the PSP folder that is in the update M33-4 into the root of the MS overwriting the files when it asks you to. Now go to Game Menu Memory Stick and run the m33-4 update. This will only take a few seconds.

    After the update is finished check and make sure it says 3.52 M33-4 for firmware. If it does say 3.52 m33-4 then format the MS 1 more time.

    You are now updated to 3.52 M33-4.
