If you have a warranty just take off the hard drive (if you have one) and send it in. That way you'll be able to keep your cod file, because it's stored on the hard drive. If it doesn't have a hard drive just send it in and see if you can recover your gamer tag (to do this you need to know the email it's on) and I think you'll still be able to keep your cod stats
