    I think you could use pandora to downgrade you slim to 1.5 and then upgrade .... orjust upgrade straight to 3.71 ....

    Sorry if I'm wrong i'm not that sure... because I don't have a Slim PSP I only have a Phat psp

    I think you have to use Universal Unbricker...

    You can not downgrade a PSP SLIM to 1.50 firmware.

    You will need to use your 3.52 M33-4 to create a Pandora Battery that will install 3.71 M33 custom firmware onto your PSP SLIM.

    Since your 3.52 M33-4 has the custom firmware on it you will need to use your PSP FAT battery as the Pandora Battery. But that is fine because the FAT Battery will fit into the PSP SLIM. You can also recover your FAT Battery to normal if you follow the steps to backup your Battery EEPROM in the guide below.

    HERE is a guide that shows you how to do this (Skip the 1.50 ADD ON part of the guide since you can not install that on a SLIM PSP).

    Once you have installed the 3.71 M33-2 custom firmware on your SLIM go HERE and download the 3.71 M33-3 firmware update. Extract the update and drag the UPDATE folder to the /GAME/PSP folder and then run the update via Game Menu Memory Stick.

    Your SLIM will now have 3.71 M33-3 firmware on it.
