A master reset will result in the loss of all data stored on the device including 3rd party applications.
This type of reset should only be used as a last resort after all other troubleshooting steps have been exhausted. It is highly recommended that you complete a backup of the device information before proceeding with the steps in this tutorial.
From the home screen, use two fingers to swipe down the Status bar.
Note: If Device Protection is not disabled, the login credentials for the Google account previously associated with the device must be entered to complete the initial setup.
Set the Backup options as preferred.
When finished, scroll to and tap Factory data reset.
Tap Delete all.
The device will completely reset and restart.
