I cant update the firmware with the tpplc utitlity tool, because of the "unknown device" status. I just can rename the Adapters, nothing more.

Try a factory reset on the adapters first. Once someone renamed the adapters, using any other powerline management tool but TP-Link's own, the tpPLC utility cannot identify its own adapters anymore. This is due to the nonstandard (and non-permanent!) way TP-Link firmware carries the device identifiers - they put the model identifier into the user changeable "unit name" field instead of the permanent make/model/version fields. [And to align with that, tpPLC does not actually program the unit name into the device, it just remembers the name in the tpPLC utility - so when you view your PLC network from another PC, the names aren't there.]

(To factory reset, hold down the link button for about 15 seconds as you power on the unit)

I have the same problem. I see my TP-WPA4220 WLAN adapter in the powerlan. I don't see my TL-PA4010P Kit adapters..
Resetting the adapters doesn't work.
