I'm writing this entry based on my own experience. At the beginning, I facing several problems such as firmware not suitable to my tablet, touch screen did not function after upgrade and etc...I felt so bad and almost give up.. for the last try,  its done successfully.. hahhahaaaa... I'm very happy, the latest firmware really work. Before this, I've sold a few models of Chinese tablet such as MID E18, SV27A and M009S.

I will teach you how to format or upgrade the firmware for tablet made in China. Generally, all tablet 7" origin from China use the firmware powered by VIA 8650 800MHz (CPU) and Android 2.2 Froyo for the operating system.

When your tablet hang or the android robot freeze or dancing without loading anymore, you can try this step for fix it... Follow the process step by step... Good luck dude...

Step 1

Download new firmware here 7" VIA8650 M009S 06.11.rar. Once done, you extract rar file and you will see this items:

In-case, your screen is not functioning or reacting to any user touch, its caused of different decoder chip that you have in your device. So need to edit some of the firmware files. There're 2 different versions of 8650 tablets, using a diff touchscreen decoder chip.
