@VykintasKuzma
Thank you for this help. But, I was unsuccessful. The modem remains stuck on EG06ALAR04A01M4G.
Here is the output:

Couple notes:
1) getting the "modem ID" was confusing at first because modem_updater has no direct command to list them. I figured out after closely looking that if you run it with no arguments, the modems are listed above the help text.
2) when I ran `modem_updater -g` it listed 2 available:
root@RUTX11:~# modem_updater -g
Available versions:
EG06ALAR02A07M4G
EG06ALAR02A07M4G_04
I tried both of them—not sure which is correct? What is the 2nd one for?
Thank you
