How to reset my L920

[Azensun]

You can do a "soft reset" or a "hard reset." Or, you can try the easiest one first, which would be to hold the power button for 10-15 seconds until the Microsoft logo comes up. This is the easiest way and doesn't wipe out your data. I would try this method first.

Settings > About > Reset my phone should do the trick if you're asking to erase the phone.
