View this info if your device is unresponsive, frozen or won't power on or off.
This device has a non-removable battery. This process can be used to simulate a "battery pull" when the device is unresponsive, frozen, or doesn't power on.
In most cases, a soft reset won't affect data on the device, unless the battery is very low.
Press and hold the Power and Volume Down buttons until the Maintenance Boot Mode screen appears (approx. 10 seconds).
From the Maintenance Boot Mode screen, select Normal Boot.
Utilize the volume buttons to cycle through the available options and the Power button to select.
The process may take up to 60 seconds to complete.
