My console seems to be stuck, I bought the console used today. I plugged it in and turned it on only to be greeted by that error. The code is "23EF 3151 B200 0700 C000 0013". I tried using the hdd from my other xbox, same problem, tried installing the latest update via both CD and USB, still the problem persists. I have also downloaded basically every xbox update going and tried it via usb, still nothing.
Anything I can try? This is really frustrating. I have no way of contacting the seller to find out what game was last inserted. The MFR date is 2006-08-17, cheers
