I have heard about Rogero custom firmware for the PS3 that does some cool stuff.

How can I downgrade my PS3 so I can install this? Can this be done on my machine? From what I understand you have to be able to downgrade to 3.55 to do this.

My firmware is: 4.31

I have the slim model.

The only way that I'm finding thus far is a hardware modification to do so.

AFAIK you can't downgrade firmware, making PS3 on older firmware slightly more valuable.

From what I know the lowest firmware version you can downgrade to is the factory version.But even this way It's not really worth it(it's rather expensive).
