Those previous commands are for Sierra modules, not Quectel modules.<br>

<br>
qmi-firmware-update can only work with Sierra modules for now. For<br>
Quectel modules like the EM12 the procedure is slightly different, and<br>
they're not yet integrated there. If someone is interested in having<br>
that added, let me know.<br>

Yes.<br>

That means QMI over MBIM actually works.<br>
<br>

<br>
That just means the module you're playing with doesn't support that<br>
specific DMS List Stored Images command. If it's a Quectel module, I<br>
would say it's common, I don't think I've seen any Quectel module<br>
supporting that command.<br>
