    I understand there are components within HEX-NET you can't talk much about, for good and valid reasons, and that's fine.

    So here's where we landed:

    1) You do NOT need a computer to update the HEX-NET at this time. All regular updates are available OTA.

    2) Aside from BL/CFB, if the USB and OTA upgrade processes don't agree, there is a bug and we should report it.

    3) Under rare circumstances, in the distant unseen future, there is a non-zero chance that BL/CFB will need a one-off USB update.

    Correct?

    I think that's essentially correct.

    I was envisioning the USB cable+Adapter to be used from an RJ-45 jack in the garage that was only about 10 feet from the car being tested. However once he has Ethernet cabling all the way from his house to the garage, he could then use another Cat5 cable to the car, an Ethernet-to-USB adapter/converter, an USB gender changer, and the USB A to B cable. It would eliminate WiFi per his desire. The problem would be finding the best adapter/converter.

    Which is also a non answer.
    I think the Way of Things has been clearly stated now. OTA and USB updates are equal for everything we care about.

    If it makes you feel better, I scanned a UDS car today and now I'm stuck on the ROD update fail-boat with you.

    Yes, that part is clearly not working as reliably as we'd like.

    With apologies to George Thorogood:

    Ross-Tech will get me Mobile tomorrow, the next day, I don't know. That don't confront me, long as I get my wireless Desktop today.
