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

Backing Up and Restoring Content

on page 38.

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
