When the update is nearly complete, and the end in the applying stage, it pops up and says please reconnect your controller. But the controller is still on and the ring on my 360 still indicates its connected also. So when i remove the battery pack and turn it back on, the pop up goes away, but then the update stops. I then get an error message with the last 8 digits being c000-0001. I looked it up and it says the console needs to be repaired?? I have had no issues with the console before trying to install this update. It worked perfectly fine until this morning.
