Factory reset

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). Factory reset is not a step to be taken lightly. It’ll permanently delete all your data and customized settings, and will remove any apps you’ve downloaded and installed. Be sure to back up any data and files you want to keep before you do a factory reset.

Performing a factory reset via settings

The most convenient way to do a factory reset is via the settings.

  1. On the Start screen, slide to the left.
  2. Tap Settings > about.
  3. Tap reset your phone, and then tap yes.

Performing a factory reset using phone buttons

If you can’t turn your phone on or access settings, you can still perform a factory reset by using the phone's buttons.

  1. Turn the power off.
  2. Press and hold the VOLUME DOWN button, and then briefly press the POWER button. Release the VOLUME DOWN button when you see an icon on the screen.
  3. Then press the following hardware buttons in sequence: VOLUME UP > VOLUME DOWN > POWER > VOLUME DOWN.
