I have a extra ps3 that was giving to me with the ylod. I fixed it last night and now i want to run a CFW 4.30. But I don't know if its possible. I have firmware 3.56 and it was manufactured in november 2007. Im thinking of getting a hardware flasher to try to downgrade but i dont know which one to get? Im a software programmer which is real good with a soldering iron. can someone just point me in the right directions? thank You guys.
