Driver installation

Before upgrade the firmware, please turn off the tablet. Hold on the Volume+ key on the side and plug the USB cable, then you’ll find the new hardware. Tips below will come out if you have never installed device driver.

Select “Install from the list or specific location(senior )(S )”

Select “rockusb.sys”under the driver progress file.

Then the driver installation of the USB device has been done.

Upgrade firmware

Open the upgrade tool, RKBatchTool.exe

After opening the upgrade tool, choose the firmware.

Browse and select the firmware.

If the cube “1″ is not green, please click “切换” to turn it to green.

Click “升级” and wait it will be done automatically.

The green turns to yellow and the place is flashing after clicking the upgrade which means it’s in upgrading.

When upgrade is done, exit the tool, unplug your tablet and reboot it.
