[qmi-firmware-update] Flashing does not work properly with Sierra em9191 (5g modem)

[Alexander Dydychkin]

Oh, thanks. You are right.
After the fix I have following issue:

1.26.10 qmi-firmware-update:
qmi-firmware-update -w /dev/cdc-wdm2 --update
adydychk/fws/atta/SWIX55C_01.07.13.00-005.cwe
 adydychk/fws/atta/SWIX55C_01.07.13.00_ATT_012.007_002.nvu
loading device information before the update...
setting firmware preference:
  firmware version: '01.07.13.00'
  config version:   '012.007_002'
  carrier:          'ATT'
rebooting in download mode...
download mode detected
error: unsupported download protocol

After that the modem is not active. I suppose that only full power off will
help me. I think that this version simply does not have support for this
modem. Right?

1.31.2 qmi-firmware-update (version based on "build-collection-basic" CI
cmd):
./qmi-firmware-update -w /dev/cdc-wdm3 --update
/home/support/adydychk/fws/atta/SWIX55C_01.07.13.00-005.cwe
 /home/support/adydychk/fws/atta/SWIX55C_01.07.13.00_ATT_012.007_002.nvu
loading device information before the update...
error: couldn't open QMI device: endpoint hangup

Any thoughts?
