I was updating my XBOX 360 since it told me there's a new required system update but it got stuck at the loading bar about 90% and I thought I would just leave it on and let it finish when it does yet it never did. I woke up in the morning and it was still at the same place and it kept on saying downloading with the loading circle still turning but I saw no progress.
What can I do?
I would begin by restarting your console if you haven't already.
When the console starts back up, if it doesn't auto start the update process again I would first clear you consoles system cache. Unfamiliar with that process, click here: http://support.xbox.com/en-US/xbox-360/troubleshoot/hardware/clear-system-cache
After you clear your cache, restart the console again and then try the update once more.
