    polling failed when writing to jeep liberty

    I've now bought 4 credits since the first two didnt populate but I cant get them to go to my device. I have the updated software and tried on both a win 7 laptop and my win 11 tower. I've tried 3 different usb cables as well. I just submitted a ticket. I know I've had similar issues but have resolved them.

    Ok I think I have progress but how do I confirm the credits are on the device? MPVI2? All I see are ways with the old version of the software and I upgraded to 4.12.4.

    I havent been getting ticket numbers for some reason.

    Just to recap, The reason for my error was that the firmware on my device needed to be updated. I finally got a call Yay!

    For anyone that runs across this error on MPVI2/MPVI2+ devices in the future you can update the firmware manually by following these steps:

    Disconnect your MPVi2 or MPVI2+ from your laptop
    Below the BT LED there is a button hidden in the dark square area
    Hold this button down.
    Now while holding this button down connect to the laptop.
    Check for a flashing PWR light. If flashing you can release the button and now open
    VCM Editor or Scanner and perform an VCM suite information log
    By clicking the HELP then VCM suite information log.
    It opens a new dialog box. Click the blue circle with the "I" in it.
    This should start the firmware updating process.
    Once complete you should be able to use your interface as intended.
    It doesn't have to be perfect, it just needs to be done in two weeks...
