I start my Xbox 360 250gig Halo edition.
machine comes on
the little swirling icon swirls a bit longer then usual but the main screen comes on.
Update is available for the xbox press ok. I press okay
Download starts and then after a few seconds:
Status Code: 3151-335A-A080-0C00-8007-2746
Now I can't log on to xbox live what so ever.
Oh and my network is rock solid and everything else on it is working just fine.
