Current libqmi/qmicli/ModemManager can both list and select installed
images. So, if your device had multiple images selectable, it would
allow you to switch between them. Now, for loading new firmware
images, I'm afraid I cannot help there. For Gobi 2k devices we use
"gobi_loader" to load the image into the device, but I'm not sure that
is applicable to Gobi 3k as you need a QDL port for that... There
probably is some way to do it via QMI, but I'm not sure it is either
described or documented somewhere. Maybe others have more ideas?
