How to use
The first thing to do is to make sure you’ve got the latest Rockchip USB drivers installed (via DriverAssistant).

Enter AndroidTool_Release_v2.38 directory, and click on AndroidTool.exe to start the program.
Connect the USB OTG port of your Rockchip device to your Windows computer, making USB debug is enabled in Android.
AndroidTool now merges the functionalities of RkBatchTool (single file firmware) and RkAndroidTool (flash the NAND flash with an image corresponding to a particular partition such as kernel, system,. boot, etc..), and hence supports the two methods:
– Single file (firmware.img) – Select Upgrade Firmware, load your device firmware, and click on Upgrade
– If you’ve got several images for the kernel, recovery, boot, parameter, you need to click on Download Image, and load the images for the partitions would want to flash, before clicking on Run to complete the firmware upgrade.
Be patient, and the firmware update should be done after a while.
