Hi, so I bought a phat PS3 model CECHA01 (60GB reads PS2) and my version now is 3.72... I saw I can have CFW at 4.80 but im not really sure about my model because i can find tuts only about the slim and the super slim... So do I need the NOR E3 flasher or can I soft-downgrade..? I have a lot of expirience with hacking and soldering if that helps... I can only find videos about downgrading with the flasher but not about installing CFW on 4.80... Thx in advance for the help and sorry for my bad english..!
