How do u downgrade your ps3. Im a mod newbie and really wanna learn. =).
if you are on OFW 3.56+ then you need E3 Flasher to downgrade to 3.55 so you can install your CFW (Custom Firmware). When you downgrade and install CFW there is a pkg called multiman that enables you to play back-up-ed games. However You can see This for Downgrading tutorial using E3 Flasher. [Small note: Don't Use Downgrade services because they can steal your CID (Console id) and sell it to other people or just use it. And when the CID is banned the PS3 Cannot go online so watch out ]
