I had my my XBOX modded. I had a 120 GB drive on it. I am trying to install a new 300 GB drive and new bios. I have 2 problems. I tried to reflash my current drive with a new bios. I got a Verification Failure message. Expected [00] Recieved [09]. Obviously you will get the error 13 on a blank drive. So my question is how can I reflash my chip?
