** How to root the tablet ** - thanks to Arctablet News
Here's a link for the forum on this topic. Most people specially those new to Android do not need this feature as it involves a bit of reading and danger of damaging the tablet. Try at your own risk. If you don't know what root is, you probably don't need it.

1. Download and unzip this file and this file.
2. Turn off the tablet. While pressing both the volume down and power button, connect the tablet to the PC via USB cable.
3. The PC will recognise the device. Use the drivers provided in the Rockchip_Batch_Tool_v1.5.zip when asked.
4. Run RKBatchTool application as administrator. If a green square lights up in the program it means its recognise the tablet.
5. Click the button next to FW Path and point to the update.img file from kasty-titanium80-41-test1.zip.
6. Click Upgrade. This process will take several minutes and the tablet will reboot.

Make sure the tablet is charged before attempting this. You should have SuperUser app to confirm if you're successful. I have done this on a Windows 7 32bit laptop and tried different USB ports. Some users say plugging in the power cable when plugging in the USB cable helps.

** How to update the firmware manually ** - will remove root
Download latest firmware here. Do NOT unzip. Save it to the root (outside any folders) of the internal memory. Unplug tablet from PC. An update message will pop up. Continue update.
