Hi, noob here. Sorry if this is a recurring post or has Been asked before. My sons Xbox 360 had the 'open tray' error and after a successful attempt at fixing it, has reappeared. So I have bought a new one (Phillips Lite on). BUT when a game is inserted, it comes up 'play DVD' ! From reading other posts I see I need to Flash the new DVD to match the old one. How do I do this ? As I said, I'm a noob, that has a basic understanding of what needs doing but need guidance. Any advice would be grateful. If you need any other info to aid you, please ask Thanks Dan.
