The "Switch" button in RKDevTool is crucial. Many users make the mistake of keeping the device in ADB mode. Here’s how the procedure typically works:

: Most Rockchip-based Single Board Computers (SBCs) only support flashing through a specific OTG-enabled Rockchip devices often communicate better with older USB 2

Do not skip this. Windows requires a system restart to properly initialize the low-level Rockchip USB filter driver.

: Locate the Maskrom (or EMMC CLK / GND ) test points on the board. Short these two points using a pair of tweezers or a metal paperclip, then plug in the USB cable. Release the short after 2 seconds. This indicates the device is detected, but the

If there is no button, look at the physical circuit board schematic for two gold pads labeled EMMC CLK (Clock) and GND (Ground). You must use a pair of metal tweezers to short (bridge) these two pads together while plugging in the USB cable. Release the short immediately after plugging it in.
