Today, I’ll make a introduction of upgrade directions of D70pro II tablet PC.
Download the upgrade pack.
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.
After opening the upgrade tool, choose the firmware.
If the cube “1″ is not green, please click “切换” to turn it to green.
