This is kinda cool. Looks like recently a couple of developers who go by OverX and HwapX have developed a nifty little tool called “Venix Downgrade” to assist in downgrading your PlayStation 3 from firmware 4.11 to 3.55.

Now, don’t think you are going to run out and do this with a little determination and a flash drive. Unfortunatley you will still need a NAND/NOR flasher of some sorts. This is compatible with; Progskeet, E3 Flasher, and Teensy 2.0++.

UPDATE: This has been proven to cause bricks… so I do not recommend using it at all!!
