The qmi-firmware-update v2 branch that I suggested already does the
wait and retries waiting between your steps 5 and 6. Only once we've
had a successful QMI communication with the device, we show the last
results messages and finish qmi-firmware-update. That is what's weird
to me; if you issue any qmicli command *after* qmi-firmware-update has
finished, then the modem should already be ready to reply QMI.

Also, note that older devices like the 9x15 family *do* require
offline+reset, not just reset. At least that's what I recall from when
I did it first time.
