HL7810 firmware update

As far as I understand sft does not work with HL7810… Can these oneclick-things run on a arm-based Linux platform?
Are delta-updates possible with HL7810, and if so, where do we find delta-archives?

Does this help to use local firmware download?

Yeah I saw this one:

1.3.4. Local Delta Firmware Upgrade Package (applicable to all modules)

But where to download these packages, not here what I can see?

Did you contact distributor to get the delta package for local download?

According to the firmware docs you are referencing, the SFT standalone package is available for the HL7810, but I don’t see it in the sources website. Only the exe is there (unless I missed it?). Also, I’ve got the same question. Can an ARM based (not x86) linux host use the SFT method on this modem?

Did you contact distributor to get the delta package for local download in ARM platform?
