Ah ok, i thought you were at cfw. (custom firmware). Just do what asddasit said. You will need to downgrade your PSP using a "Pandora's Battery and "Magic Memory Stick". It is fairly easy to make if you have access to another PSP that has custom firmware on it or is at 1.50 official firmware.

Right now, it is impossible to upgrade from 3.52 Official Firmware to 3.71 M33-2 Custom Firmware. So you will need a pandora's battery to downgrade.

i already have the pandora battery

i just need the instructions how to upgrade it to 3.71 m33-2

You will also need a Memory Stick with the certain files on it in order for the Battery to work.

I'm not sure but does that have a chance to brick? I think it is a last resort option or something? not sure.

Ah ok cool, I thought i read somewhere where it was a bad option. But it upgrades the PSP straight to 3.71 M33 from any firmwarE?
