Ray,
I’m aware on how to get it into programming mode. The question remains why doesn’t OTA work? And for me it’s a hassle since my Opengarage unit is mounted up high with double stick tape. Because the unit is mounted, I have climb up a ladder while bringing up Surface along with me, then I have to hold the USB cable near the port while I hold on to the button as I plug in the USB cable. Certainly not advisable to do and I wouldn’t if I could get OTA to work.
