I have a xbox360 that has cfw on and it has not taken the latest update to reset it. I had the xbox flashed by someone else and they didnt save the keys. I would like to buy the xkey or xboxdock to load games from my hd. What do I need to buy to get the keys. I think I need to buy the glitcher, but not really sure. Could use some spoon feeding here with a link as to what I need.
