My xbox 360 froze while updating
This issue is likely due to a high increase in update traffic on the Microsoft server due to the Xbox One console launch, similair to the launch of the PS4.
A possible work-around would be to attempt to update your console at a more optimal performance time, such as early in the morning (2AM - 10AM), as you are more likely to encounter a receptive updating time with people at school or work.
Some of IGN's readers have noted that game installs seem to sputter out around the 97% mark, stalling out indefinitely.
Microsoft has issued some confirmed reports of these issues being fixed via their Xbox One Support forums.
The steps involve disconnecting your Xbox One console from the Internet and powering the console off manually with your finger.
Attempt to install the game once you boot the console back up, but make sure you're not connected to your Internet provider.
In at least one reported case, a console refusing to download the update spontaneously begin work, sometimes after hours of waiting.
This could be related to back-end network connectivity issues on the Microsoft server side.
By simply weathering the storm, the Xbox One will eventually become ready and accessible for installation.
The 360 stores games updates in the cache, a dedicated area of the hard drive where it can retrieve those updates faster than from a DVD.
The cache is a limited amount of storage, and does not store the updates for all games at the same time.
In addition to title updating issues, it is generally considered faster to install discs offline and then connecting to the Xbox Live network.
This is because Xbox Live will first install any title updates which, depending on network status, may cause slowdowns.
