These instructions may also work on other Rockchip based devices.
I could not find a working method to root this tablet using Linux, so here are the steps for rooting this tablet successfully using Windows:
1: You need to enable the Developer options. Go to the Settings app. Tap on "About tablet", then tap on the Build number seven times until a message is displayed saying "you are now a developer". The "Developer options" section will now be displayed in the Settings app.
2: Tap on "Developer options". Make sure "USB debugging" is enabled.
3: You now need to install the Rockchip device drivers on Windows. Go to this link to download RK Driver Assistant. This program should automatically install the correct drivers for your device.
4: Go to the Device Manager in Windows. Right click on your tablet, and click "Update driver software".
5: Download and install "Kingo Android Root" on Windows. This program should root your tablet. If Kingo Android Root does not find your tablet, try rebooting and/or plug the tablet into a different USB port.
You should now have root access on your tablet.
