Xbox 360 error codes

Make sure the disk is clean.
Reinsert and try again.
If it does not try to update again and it tries play the game but does not work and it is not because it cannot read the disk then go to the settings, hard drive and go to "System Cache" and delete.
This will delete all temporary files. Which means all small updates for games will be deleted. I reccomend doing this as it may be an error due to the update being stopped halfway through therefore being unfinished. So the xbox may recognise that the update has been installed but because it is unfinished then it may not be able to start the game.

If this still does not work try disconnecting from the internet as it will not ask for an update and you will be able to play the game without it. If this does not work and the game does not play it may be a problem with the disk.
First I would suggest playing the disk in a friend's xbox. If it still doesn't work, take the disk back to the shop and get it replaced.
