Came across this excellent video and software for rooting almost any Android 4.0 Ice Cream Sandwich or Android 4.1 Jelly Bean smartphone.
First you will need to install the PDAnet ADB drivers to root your MTK6575 and MTK6577 phone. PDAnet ADB Drivers
The JiaYu G2S has been successfully rooted with this method, so we do know that it will work with at least some MTK China phones.
Please report back to GizBeat and comment in this post with your success and any links to ADB drivers you may have.

As always, you attempt to root or modify your phone at your own risk. GizBeat and I can’t be held responsible for any bricked phones or dead barnyard chickens resulting from attempting these methods.
