I'm having the same problem after the update. Screen freezes every time it tries to sign-in to Live. Can't get to the dashboard. Only works if I go off-line. Tried the unplug xbox, router, modem route but no dice. Spoke to Tech Support and they told
me to bring the Xbox in! This is before I realized that I was not the only one experiencing this problem. Good thing I decided to check the forums before sending it in. Grrr. Hope it sorts itself out. Still waiting for official word from MS on this issue.
