3.90 official downgrade

[michalt441]

Hi,
My friend got a PSP too, and wants Doom, Duke Nukem 3D and other cool stuff like this on his PSP too, like I got it. He got official FW 3.90, so it's not homebrew compatible. But my PSP was purchased on Ebay, which already could play homebrew, so I don't know how do I hack his PSP so he could play Duke Nukem 3D, Doom and other homebrew on PSP.

Please tell me how do I do downgrade official FW 3.90 to 1.50. My friend wants it really badly.
