Someone brought me his xbox for me to repair but I can't find what to do. I modded the xbox 1 year ago, it was working fine from there but now there's two problems (maybe they are linked, I dunno). First thing : When I plug my High Definition adapter everything turns to black and white. Second thing : the xbox won't run backups anymore and even worst, it won't load evox most of the time, in fact, without a boot disc the xbox only reboots and reboots again. I tried reflashing the bios, it worked (I mean the flashing), but all the problems are still there. I really need help on this one. Thanks.
