You need PC to  hard reset or factory reset your device. I already tried this procedure. Just follow carefully the procedure so you will not brick your device. This tablet has a Rockchip CPU. I dont have the picture of the tablet (i forgot to took one). How ever you can see the device that I took when I was installing the driver. And the boot logo of this tablet is C-DR King VE Series.

You can fix the following issue:

1. Pattern Lock
2. Gmail Account Lock up
3. Password Problem
4. If your tablet does not boot up properly (if the firmware is not totally damaged)
5. Force closing apps.
