Flashed an xbox 360 and tried to play nba homecourt, asked to be updated and got error 66, ring of death, returned it and got a new xbox and flashed. Now when I try to play Guitar Hero or Forza, It asks me to update or I can't play the game. I have dashboard 2xxx. question is if I update from xbox live, I will get banned, has anybody had any experience updating from a burned CD from their website? http://www.xbox.com/en-US/support/systemuse/xbox360/console/updates.htm What should I do, I don't want another ring of death!
