Hi guys! I'm a newcomer here, its nice to join to this nice community. I have a question. I have PS3 2508B 0C 4.83 official firmware. Finally I decide to install CFW 4.92 Evilnat. Do I need install 4.92 official firmware before CFW 4.92 Evilnat or its OK to install Evilnat with my old 4.83 official firmware? Thank you!
