It shouldn't really have needed to download the SWI9X30C_02.20.03.00.cwe
file in this case, since it was already there. Don't know if it matters
much, but the "set firmware preference" request should have requested
the "pri" file only here.

Will  qmi-firmware-update look at the returned list of images to
download, Aleksander?  Or will it just download everything on the
command line anyway?

After reading the docs Aleksander pointed to earlier today, I believe it
doesn't matter wrt flashing.  The bootloader will just drop the
redundant file.  But it takes some time to send a 64MB file to the
modem, so it might be worth it trying to avoid that.  At least for the
more common(?) operation of switching "carrier", while reusing the
running firmware version.
