Restore your Lumia 820 to factory settings

You can restore your Nokia Lumia 820 to factory settings by following the instructions below. This can be useful if your phone continually freezes, fails to respond or you’ve forgotten the security locks you’ve set up to access the phone.

Important: Restoring your Lumia 820 to factory settings will wipe all phone data so if you’re not locked out of the phone you should first back up your data to your PC or to your Mac, and synchronise your phone with your Windows Live account. The reset won’t delete data saved to your SIM.
