Starting Xbox one sign in

The update has been done and that is as far as I have been able to get. IT won't accept my microsoft account from that point

If brand new it has to update and could take a while , if not the perform a factory reset

Try changing the password on your microsoft account and then signing in to xbox live on a computer or moible divice

Same here - can no longer sign into Xbox Live on Xbox One since signing up for the early update. Not a good start to this preview system; thinking registering was a bad idea.
