717 The LA66 USB LoRaWAN Adapter is the same as the LA66 LoRaWAN Shield update method
718
719 Just use the yellow jumper cap to short the BOOT corner and the RX corner, and then press the RESET button (without the jumper cap, you can directly short the BOOT corner and the RX corner with a wire to achieve the same effect)
