So, this was originally a problem that started at the back end of last year, but has continued up 'til now as I still haven't found a fix. It all started with a prompt to download a new update last October-ish, which was all fine and dandy until 30 minutes or so after the install had finished my session of Fifa 14 was brought swiftly to an end by a random freeze screen during gameplay. I figured it was nothing, because freezing is a common occurrence every now and then. Sadly, though, this was actually a far bigger problem than I initially thought it to be. In short, the xbox will boot up normally most of the time(though sometimes there's no xbox logo screen) only to shortly after be met with a white box with the message: "Can't update console. Please visit www.xbox.com/support", followed by an error code, which I can't remember right now, but will post later on if needs be. Also, I can't connect my wireless controller to the console; both the xbox and the controller itself will proceed with the routine, flashing green light, but nothing happens afterwards. If I connect the wired-internet cable, sometimes the console will try to update, only to then be promptly thrown back to the "Cannot Update Console" screen.
What makes this all the more frustrating is that the console had nothing wrong with it prior to the update, which leads me to believe it was indeed the update that caused the problem. As I stated, it was only roughly 30 minutes after the update that the console froze and proceeded to give the error messages on the following boot-ups.
Any fixes for this would be greatly appreciated. Thanks!
