The problem is I haven't figured out how to connect to xbox live yet, all I have is a cellular card for internet access,
I've tried to rig up my laptop to the 360, but I't can't seem to detect my network hardware, even though i've marked it to share, created a bridge tried several things...
Supposedly you don't need a crossover cable for a 360 due to some switch thing, I just have a normal line right now. I might try a crossover and see if that works.
So until I get that figured out, I'm trying to see if there is some way to update my 360 offline.
