If your Ellipsis 7 somehow ends up in Factory Mode, the screen will display options in foreign characters.
In order to exit Factory Mode, press the Volume Down button until the last line of text is highlighted in blue. Then press the Volume Up button to make the selection. The device should now restart.
If the Volume buttons are not responding, please allow the tablet's battery to fully drain. After charging, your Ellipsis 7 should power back on in normal mode.
