Hi, I am using a Linux PC. I need to understand more about firmware upgrade. Is it possible to upgrade the modem firmware with AT commands? Or is it possible with QMICLI commands alone? There are commands for setting preference, but is there a way to give the path of the .spk file to the modem to…

You can use the MBPL sdk You can see this discussion thread: [image] How to update the RC7620 firmware with "qmi-update-firmware" RC76 How did you enter at!boothold then? You should use /dev/ttyUSB2, right?

I could enter into boot and hold mode with qmicli:dms commands –dms-set-firmware-preference=… –dms-set-operating-mode=offline –dms-set-operating-mode=reset At this point, as expected I can see only one ttyUSB. Looking for a simple integratable solution for downloading the firmware to the modem. …

How about at!gstatus? Can you bring it back to online by at+cfun=1

Ok, just to reiterate, there are the steps: Set preference, go to offline and then reset with QMI->DMS After modem reboot, as expected I can see that we have only on ttyUSB exposed. So I cannot run any AT commands. Dont go for firmware update by just powercycle again and I can see the three ttyUSB…

why the AT!IMPREF is different this time?

Yes, because when you asked me the response for it, I already retrieved the status back to online to proceed with my work (had to do actual firmware update). But then I realized you meant the response at the point where it was not possible to get back to ‘online’ (without actual firmware update), is…
