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
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™
Xperia™ Companion on page 39.
