HL7800 Firmware update

Hi,

I am confused about how to update the HL7800 firmware. I searched in the ressources
https://source.sierrawireless.com/resources/#tags=HL7800
but "Firmware&drivers heeds no result.

Can someone please point me to a source an possibly a description how to do the update?

The module I am using outputs this info. How to spot the current FW?
