I just installed iKommunikate and try to update the firmware from Firmware Version: 2016102500
Firmware Date: Oct 25 2016 to the current one.
Try the check for firmwrae updates -Button it says:
Firmware Update: New Version Available (2017042600)
but after hit on Download updated firmware, it shows:
Firmware Update: Downloading (0% complete)
and stays forever on 0% (waited about 30 min)
Try to Manual firmware upload
downloaded and unzipd the file (ikfirmware_2017042600.mdm)
It uploads it successfully (??) andy says:
Upload complete, reboot required.
Aber doing a reboot, the old fimeware is still running
I tried this with chrome and with firefox (latest versions)
