I just installed an xecuter 3 in a 1.3 xbox. everything works fine. When i go to flash it with the 1959 bios(had a disk from a friend) it flashs and when i turn the xbox back on i hear the sound but their is no picture. i have tried holding the white button but nothing works. when i disable the xecuter 3 it boots to the microsoft dash fine. what can i do? Also i already tried redoing points 13 and 14 twice. and it still doesnt boot. what can i do. Also when i try to reflash it it freezes.
