Factory Reset

Do a factory reset to change your phone back to its original state before the first time you turned it on. If you’re passing your phone on to someone else or your phone has a persistent problem that cannot be solved, you can perform a factory reset (also called a hard reset).

Important: Factory reset is not a step to be taken lightly. It will remove your primary Microsoft account and you may lose data if it has not been synced. Be sure to back up any data and files you want to keep before you do a factory reset.

A factory reset may not permanently erase all data from your phone, including personal information, which may be recoverable by others.

  1. Turn the phone off.
  2. Press and hold the Volume down button, and then press and hold the Power button.
  3. When the phone vibrates, release the Power button when you see an icon on the screen.
