How to Install Sierra firmware within OpenWRT CLI?

IoT Modules MC/EM Series
7

I am getting this error:

qmi-firmware-update -t /dev/ttyUSB0 --update-qdl /tmp/SWI9X30C_02.24.05.06_Generic_002.026_000_1/SWI9X30C_02.24.05.06.cwe /tmp/SWI9X30C_02.24.05.06_Generic_002.026_000_1/SWI9X30C_02.24.05.06_GENERIC_002.026_000.nvu 

error: error creating device: unexpected response received in dload sdp: 0x70

UPDATE: Nevermind, ran the steps a few times and the modem was at the right “window” to accept the update command:

Also, I did change the USBPID and PRIID using some info from here: https://forum.pfsense.org/index.php?topic=123828.0. Mine was a Lenovo branded card with USBPID 9079 and PRIID 9905228 which was for a “Lenovo-Tablet”.

Thank you very much Alexsander. I beat myself up with the Firmware_Download program in Sample_Apps as per Sierra Wireless instructions but even though it said it was successful, the image never went to the modem (none of the slots show it) as slot 3 now shows it with you update program
