Alternatively, if you are running Android and can access ADB, you can reboot the device to loader mode 'adb reboot bootloader' then use the rkdeveloptool to reset the device into maskrom mode 'rkdeveloptool rd 3' or Windows RKDevTool Switch button to go to maskrom mode.

Flash Images to eMMC on Board
