i installed an X3 in a machine. take note i tried another mod chip in this same machine and it worked fine. I turned the machine on and it laoded into the flashbios screen. When i go to try and flash the bios it freezes and sits there. something odd i noticed was when i go to turn the xbox off the modchip starts to flash. so if i hold the power button down it will flash but then the xbox turns off before it can finish. What is up with this thing??
