How to format TEAC TC-7120 Tablet I have  - TEAC TC-7120 tablet and I want to entirely format it using just with the "volume +/-" and "power" on buttons . 

I haven't any approach to its OS since it locked and I don't have any idea about its password or Google account for recovery .  

Is there any solution for that ?  I looking for solution like this approach  - https://www.youtube.com/watch?v=jtKDpawgeLs (just button using) .
Askmefast.com provides a hardware reset solution for that tablet:


Power off
Press and hold Power and Volume Up together
When it turns on (nothing may appear on screen or only the logo) release Volume Up (keep holding Power)
Keep holding Power and press and hold Volume Down


This should launch the reset mode and after a restart it should erase all apps and settings.
