Aparently in order to upgrade you need the original blu ray daughter board, even if its broke....Is this true even for downgrading? I have a 60GB that will DOWNGRADE from 3.55 to 3.41 CFW that bypasses the blu ray, but it wont go any lower. I need it to downgrade to 3.15 and lower so I can remarry a new blu ray board. I dont have the original board anymore. SO does anyone know if there is a 3.15 pup that bypasses the blue ray? or any pups besides 3.41 for that matter?
