Hello Had my Xbox chipped with a matrix modchip a few months back and its been fine.Occasionally I'd need to restart it a few time to get it into the evolutionx dashboard but its always got there in the end. Now its dead. It seems to boot and the Xbox logo is green (instead of red as it should be ). Thn it drops into an error screen "13" .The chip itself seems to be installed correctly.(just checked it...solid green light). I'm assuming the bios on the chip has become corrupted somehow . If I reflash it in the usual manner will that be all I need to do? I won't have to reinstall the harddrive from scratch again? Any help??
