    You can not run games off MS with 3.50 official firmware. You will need to downgrade to 1,50 then upgrade to a CFW like 3.52 M33-4.

    You have 2 options to downgrade.

    1) Lumines downgrader. You will need a unpatched copy of Lumines game (EU (ULES00043) or US (ULUS10002) version). Here is a GUIDE for the downgrader (Look under the -3.10 - 3.50 Any Motherboard section)

    OR

    2) use Pandora Battery unbricker/downgrader which you will need a PSP that has 1.50 or custom firmware on it to run the unsigned code to create the Pandora battery to downgrade your PSP. (You can not use your official 3.50 firmware to create the Pandora Battery). Here is a GUIDE on how to create it.

    After you use 1 of the 2 methods above to get to 1.50 then follow the mini-guide below to upgrade to 3.52 M33-4 custom firmware.

    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 and the kxploitpatcher and kxploitpatcher% folders to the PSP MS directory of ms0:/PSP/GAME folder.

    Now go to Game Menu Memory Stick and run the KXploit Permanent Patcher. It should run and say patched successfully and reboot back to the XMB.

    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 inside that update folder 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.

    if you follow larrylje's steps to upgrade to 3.52 m33-4, you will not brick.
