For anyone looking to downgrade the firmware on their PlayStation 3 it seems while it has been hacked you will have to wait a while longer yet. KaKaRoToKS has tweeted that the downgrade that he had previously used to downgrade a PS3 can’t be repeated.
This means that until a hack allowing downgrading of any PlayStation 3’s firmware is made a lot less PS3 owners will be able to easily hack the PS3 which for Sony is good news. The exact tweet from KaKaRoToKS is below and it seems he is already looking for another way so I doubt it will be too long before another possible firmware downgrade comes to light.
