I hate to ask..and yes I'm a noob and have searched the forums but ...
I want to avoid turning my PSP into a brick. I reveived my GPS290 today and want to start the software install for your custom 3.03 firmware. The instructions you point to are for installing 3.02. Can I back up my PSP somehow in case I mess up ?
Do I need the 150,302 and EBOOT PBP files ?
As a first timer- I'm a bit confused where to start.
Appreciate any help in advance...thank you.
Joe
