1) How to Install ADB driver
- After connect to USB (make sure USB debugging enabled and don't mount the mass storage device)
- The option to activate debugging you find under settings and then development options
-You will find that RK2926 is recognized in the Device Manager and the drivers will be installed (It worked for me in Windows 7 / 8 )
- If your Computer doesn't recognize your device you must Install the ADB driver by yourself
- Usually Universal ADB drivers here work http://adbdriver.com/
2) How to ROOT
Using adb tool from Android SDK is not working for RK2926 device. The Only ADB App that worked is from 'ROOT.bat' here contain is the only adb that can see my device.

Just run the root.bat and your device will be rooted after the device restarts. You can verify your root Access with root checker from the market.
