No pop up or anything asking to update?

did it come up during the install asking if you would like to update the game? if it did you may need to uninstall and reinstall, if it pops up asking you to do an update decline it and let the game finish installing, then you can do the updates needed
if required.

This from RussPay works, and you can do it without turning off the console itself,when the pop up comes up asking to update the game just select update later and your good to go.

Same here. E66 error pops up whenever I update my Xbox 360 because the game asked me to. How to solve this?

mine has happened the reverse.....the slim updated, but the two arcades will not show the "update or be signed out of live" notification...

update started yesterday again..bout time
