I registered my banned 360 to see if I could send it off to them for repair in case it breaks and I need a new one. I did that successfully. I got a 3 rrod machine from someone at work but the MS support won't let me register it and says I need to phone them. The console is not modified in any way except for x-clamp and a few cooling mods. Anyone know why I can't register it? My plan was to register the serial number with the unbanned console, swap the boards, and send it off.
