Try the universal unbricker V2?I'm not sure if the V2 flashes to 3.60M33, so don't try until someone confirms it.

I don't think there's a downgrade from 3.71M33 to 3.60M33.And the Unbricker isn't just an unbricker.It overwrites your flash to change it's firmware, just like the Pandora's Battery.It downgrades and unbricks.

Just to update the thread and to tell you that you can solve this problem.

Hoping that you have backed up a nand from 3.60M33, you can recover the nand into the PSP to re-flash into 3.60M33.Don't use a nand from another PSP.

If that doesn't work, then try one the Unbricker V2, not V3 because V3 does a flash into 3.71M33, while the V2 flashes into 3.60M33, but you must do this without seeing the screen.Just read the readme and you'll know.

yes i agree, that seems like the only way seeing as you cannot downgrade w/out a pandora.

is there a way to use both 3.60 m33 firwmare and 3.71 m33? some games only work on 3.60 m33 and some games only work on 3.71 m33. So if there was a way to use both then all games work on the psp slim

you cant use both at the same time.
