Just bough a second hand xbox,which was flashed(dunno with what version) with dashboard 08955
I have tried everything except activate.iso which i can't find(if any link i will appreciate it)
Half way open,power circle,sammy
Ain't got any ck3 probe or usb,just doing it with mobo
Is my last resort activate.iso or i can do anything else?
