I own a 2007 PS3 80GB CECHE01 console, banned 2 years ago. I had a cfw hermes 3.41 version installed on this PS3 for a long time. Yesterday, I decided to upgrade the ps3 to that latest version which is 3.70 (thinking that it wasn't going to be banned anymore). After upgrading, I tried to log in with my new account and received a message saying that I'm "Permantly banned". Now I'm stuck with no custom firmware and banned.
Here's my question, Can I unban my console changing the motherboard? If yes, would it work with a 20gb ceche01mg console motherboard ?
