I stumbled across this post yesterday, the tool also works for our lovely Rockchip 3066 tablets. How to Root Teclast A10 Dual-core The tool is all in Chinese but you don't need to read whats happening anyway. The tablet reboots itself twice. After the first reboot I had to hard reset. These are the steps I took Install app on Windows (7Pro x64) turn developer mode on device (Sumvision Cyclone Titan 9.7", Rockchip 3066, Mali400, Android 4.0.4) plug the device in and wait for the tool to recognize it click the button next to the only english word on the app 'ROOT' wait a minute or two and the device reboots i had to hard reset here turn on device again after a minute the tablet rebooted walla, Rooted rockchip 3066 device. alternative link for Root Tool Multiupload.nl - upload your files to multiple file hosting sites!
