Hi I am a newbie here, I just bought a used wopad M12 (CHINA MADE) from the internet. Now, my WOPAD M12 is not working, it fails to start when I press on the button to power it but it is not responding. I thought it might be low in battery so I charge it overnight, but nothing seems to work. It remained cold and could not power up, the tablet did not drop or suffer any physical damage, the day before it was working normally. Need help - !!!!!!
