anyone has encountered this and can help me what I am missing with usb mode qflash update. Do I need to short the j021 and usb mode pins to get this working.

I sent AT+QDOWNLOAD=1 and power cycle the router and it detected the com9 port in my PC and I start the flashing fw but it keeps faling at fdl2 and the com port9 disappear in my device manager.

anyone’s help is highly appreciated!
