The only way that you can downgrade now is with a flasher. There are kits that you can buy or you can send it off to someone and have them do it. It all depends on what ps3 you have. If you have a nor chip you can get a teensy, e3 or the progskeet. If you have a NAND then the progskeet is the way to go. For the nands are a little harder. Thanks.
