My Xbox froze while I was downloading Gears of War 3 mappack, and after I restarted my xbox, it started to tell me to update (I already have 16203)
However, the update download progress bar would move slowly and even rewind. Eventually a windows poped up giving me error code
I tried all the steps here http://forums.xbox.com/xbox_forums/xbox_support/f/9/t/153327.aspx
but nothing worked. (When I tried the USB method, the update was installed, but after reboot, the system still asked me to update)
This is very annoying.
