for me, setting
qmicli -d /dev/cdc-wdm0 --dms-set-firmware-preference="02.33.03.00,002.007_001,GENERIC"
power cycling (unplugging) the device and then manually updating the firmware via
deviceid=`lsusb | grep -i -E '1199:9071|1199:9079|413C:81B6' | awk '{print $6}'`
qmi-firmware-update --update -d "$deviceid" SWI9X30C_02.33.03.00.cwe SWI9X30C_02.33.03.00_GENERIC_002.072_001.nvu
got me a Dell-branded EM7455 back to life (was stuck in low power mode with a fw mismatch). The deviceid
was already set, so maybe it is smarter to run this command first.

This is essential for solving LPM lock-in issues caused by IMSWITCH:1
due to fw/config mismatches.
IMHO it should at least be included somewhere in the README.md for poor dudes like me to find.
I overlooked this issue and wasted numerous hours trying to find a way to override these weird "preferences".
Finally found this (version adapted) command hidden in some linux forum and was able to get my modem working:
qmicli -p -d /dev/cdc-wdm0 --device-open-mbim --dms-set-firmware-preference=02.38.00.00,002.082_000,GENERIC
(I updated the fw first, so the order really doesn't matter.)
I was not able to find any AT command for doing this, though I assume this command does something alike.
