Update Instructions, Tools, and Drivers

Download the Driver Assistant and the RKDev Tools from our file-sharing site. Both must then be unzipped.

1. Install "DriverAssistant". After installation, the PC will recognize the display. If ADB drivers are already installed on the device, the tablet may not be recognized. Please uninstall these ADB drivers first.

2. Launch the RKDev tool Download and launch it

3. First, connect the blue outer USB-A port next to the power jack to the PC.

Now press the Vol+ button and the power button on the back at the same time and connect the power. You should now see a "Loader Device" in RKDevTool. You can now skip to step 5.

If no ADB/Loader device is detected, you must go to Go to Settings > About the Tablet and tap the build number seven times. This will enable developer mode.

You can find this under Settings/System. There, you'll need to enable USB debugging. You must also turn off "Turn on USB Host" under Settings/System. Note: When switching to an unlicensed version of Google or to Linux, you must click "Erase All" in RKDevTool under "Advanced Functions."

4. You should now see an ADB device in the RK-Dev Tool. Then press the "Switch" button in the RK-Dev Tool. The device will reboot into loader mode after a few seconds.
5. Click the "Firmware" button under the "Upgrade Firmware" tab and select the Linux/Android image.

6. Tap the "Upgrade" button. The firmware should now be uploaded to the tablet.
7. The device will restart automatically after the update is complete.

If USB Host is turned off and USB debugging is enabled, it’s easier to enter Loader Mode. To do this, first connect the USB cable. Then press the Volume + button and connect the Power/Ethernet cable to the tablet. After holding the buttons for about 5 seconds, Loader Mode will appear in the RKDev tool.
