Hello, Im having trouble updating my xbox 360 dash and now I cannot use it. My Xbox has LT+ 1.9. I was using a FIFA12 backup for the first time and it needed an update to the dash. I accepted and when the console restarted it stated "unable to install the update, please reinsert the disc." Now, I cant even use the console its locked in this step even with reboots. How can I install the new dash or abort the installation? Thank You.
