[bandball50]

I have 3.80 M33-5 on my phat PSP and i want to downgrade to 3.03 OE-C for the customizing...how do I do that??

[sci-fi]

what you are doing is hard and requires a little knowledge with psp downgrading.

if you already have a pandora then you will go back to 1.50 and install 3.03OE-C

if you don't own a pandora then softmod 1st your batt then downgrade to 1.50 to 3.03OE-C

Tools you need:
1. Hellcat's Pandora Installer for 3.xx R3
2. 1.50 Eboot
3. 3.03OE-C firmware
4. 3.03 Eboot

That's all and good luck
