Reset Device

It may be necessary to perform a reset if your device fails to respond when buttons are pressed or the screen is tapped.

Warning: 

This will erase all your personal information, any contacts stored on your device and any programs that have been installed. You should only perform a clean boot when all other options have failed to restore your device to an operational state.

Hard Reset Via Phone Buttons:

To hard reset hold the volume down, power button and camera button until the phone vibrates, then release the power button and keep the volume down and camera button down for another 5 seconds. Your phone should then reset to factory state.
