Firstly i tried downloading the update which came out on the 16th feb 2012, after trying several times same message came up "update failed". So i then followed instructions on the forums, look for any corrupted data and delete off hhd. after that the update still didnt work, i then tried manually updating it myself through usb. that worked... but when i try and play modern warefare 3 it requires an update, no matter what i do the update does not download ive checked everything else its fine.
i've come to the conclusion that my console is unable to download any updates since this update has come out, i have a xbox 360 slim about 1 year old
status code that comes up is : 397D-0000-D080-0200-8007-274C
