A password or swipe pattern must not be forgotten, other-

3.9 Reset to factory settings
(Backup & Reset)
If you want to pass on or sell your Acepad, reset the device
to factory settings. All personal data will be lost during this
process, so please backup your data first and then proceed
as follows:
“Settings -> System -> Advanced -> Reset options -> Erase
all data (factory reset)”
We also recommend this procedure if there is a noticeable
loss of performance from the device, caused by an overload-
ed memory or malware.
To reset the Acepad without touch gestures if you forget your
password or if the touch screen fails, first deactivate your
device by pressing the reset button below the volume control
with a slender object. After ten seconds, restart it by press-
ing the start button and the volume control simultaneously
for several seconds. You will now enter the developer menu
“Factory Mode”.
Use the Volume down button to navigate to the “Clear eMMC”
item and confirm your selection by briefly pressing the Start
button. Your Acepad will now perform a factory reset and
then boot as usual. During this procedure, please ensure that
the battery is sufficiently charged.
