I have flashed my 9504 drive with lt3.0 and I'm not running the newest dashboard. Everything was going well. I played 5-6 of my backed up games(I own all the games I've burned btw) but somthing went wrong. I burned assassins creed revalation and this time it asked me to update. Thinking that I was not connected to Xbox live, I chose to update. But then I got this grey screen that said cannot update system and everytime I turn my Xbox on. I cannot leave the screen and there are a whole bunch of error codes at the bottom. What happend??
