Error 335A occurs when you download an Xbox 360 console software update

Problem

You see the following error code and message when you’re downloading an Xbox 360 console software update:

Can't download the update. To test your connection, open System Settings and select Network Settings, Test Xbox Live Connection.

Status code: 335A-xxxx-xxxx-xxxx-xxxx-xxxx

Note The “x” digits vary.

This may mean that there is a network issue, insufficient space on your storage device, a problem with the storage device or an issue with the system cache.

Solutions

Solution 1: Try installing the update again

  1. Restart your console.
  2. Press the Xbox Guide button on your controller (centre X button on your controller).
  3. Go to Settings, and then select System Settings.
  4. Select Network Settings.
  5. Select Wired Network or your wireless network name (if you are prompted to do so).
  6. Select Test Xbox Live Connection.
  7. Select Yes if you are prompted to update your console software.

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 Xbox 360 content.

If this does not fix the problem, try the next solution.

Solution 3: Clear the system cache

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

After you have cleared the cache, try the update again. If this does not fix the problem, try the next solution.

Solution 4: Reinsert the storage device

  • 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 you have replaced the storage device, try the update again. If this does not fix the problem, try the next solution.
