1. Short ground and "pin in red circle".
2. Connect the first usb from the rear to pc (win11 in my case).
3. From power on the device manager should immediately pick up a new device, and the short is no longer needed.
Recognized: without driver "GX... chip", with "lib-usb32 usb devices" driver already installed "WorldCup Device".
Amlogic's USB Burning Tool's must be v2.*, and it comes with the driver.
One problem: after reflashing from armbian (emmc), in android a msg pops up asking for a "U disk to install BoardTest"
that doesn't let you do much, this havent come up after reflashing from coreelec, nor after failing android upgrade...
Device is still good for playing with other systems.
