Solution 2: Make sure you have enough storage space

The latest console software update requires at least 190 megabytes (MB) of storage space (or 256 MB if you live in Japan). If you don’t have enough free space, you need to move or delete some items. See Copy, move or delete content.

If this didn’t resolve the problem, try the next solution.

Removing the temporary files on your console might solve the problem. See How to clear your Xbox 360 system cache.

After clearing the cache, try the update again. If this didn’t resolve the problem, try the next solution.

• If you’re using an Xbox 360 Memory Unit or a USB flash drive instead of a hard drive, remove and reinsert the Memory Unit or USB flash drive.
• If you have a hard drive, try removing and adding the hard drive again.

After replacing the storage device, try the update again. If this didn’t resolve the problem, try the next solution.
