Updating your device wirelessly
Use the Software update application to update your device software wirelessly. The
updates you can download over a mobile network depend on your operator. It is
recommended to use a Wi-Fi network instead of a mobile network to download
new software so that you can avoid data traffic costs.

Restarting, resetting and repairing
You can force your device to restart or shut down if it stops responding or won't
restart normally. No settings or personal data get deleted.
You can also reset your device to its original factory settings. This action is
sometimes necessary if your device stops functioning properly, but note that if you
want to keep any important data, you should first back up this data to a memory
card or other non-internal memory. For more information, see
synchronising with a Google account on page 42.
If your device fails to turn on or you want to reset your device’s software, you can
use Xperia Companion to repair your device. For more information on using Xperia
Companion, see Xperia Companion web site
