You will have to reset the Tablet, it will remove all data and return the device to new, but this cannot be avoided.
To do this
At first, hold down the Power button to switch off the device.
In the next step, press and hold the Volume Up + Power button for a couple of seconds.
You should release all keys when the white text appears on the screen's left corner.
Next, quickly press the following combination of keys: Volume Down -> Volume Up -> Volume Up -> Volume Down.
After a while you should be in the Recovery Mode.
Then select "wipe data/factory reset" by using Volume Down to scroll and Power button to confirm.
Select "Yes--delete all user data". Use Volume Down button to scroll and Power key to select.
To restart the phone, select "reboot system now".
The tablet is as new and can be used again.
