Ahh, I think this modem is in MBIM mode, not in QMI mode. And
qmi-firmware-update can work with MBIM modems, but only if the QMI
over MBIM support was built in libqmi.
Can you rebuild your libqmi making sure you specify -Dmbim_qmux=true?

Also, when launching the qmi-firmware-update program, try to use the
additional "-p" option, so that the proxy is always used.

Could you try those 2 things?
