nah dnt do that
set the bank switches to off on off off. it shud bring up the normal blue 3.0.3 flashbios screen. after that make a disk with a x3_1959 on it and then whilst on the flashbios screen change the bank to on on off off but dnt reset ur box or anyfin
click flash from disk and then it will flash over the crappy m8 u put on. evryfin shud b fine then. ive jus done it myself
no need to use the backup bios
