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 + Volume Down buttons for approximately 10 seconds or until the device power cycles.
Allow several seconds for the Maintenance Boot Mode screen to appear.
From the Maintenance Boot Mode screen, select Normal Boot.
Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select.
Allow up to 90 seconds for the reset to complete.
