For those who think they destroyed the dongle by flashing (purple colour on 1-2) please try to flash only with windows 7. Windows 10 fails. Mine did not brick.
Now for those who want to turn this dongle to airplay compatible using iphone 12 ipad etc then this is the solution.
download and flash firmware 18.0. (ergotech v18)

Its been quite some time since I last posted but I was desperate with airplay failing to play on my smart TV.
Other solutions buy a chromecast dongle but this inexpensive miracast dongle works great too and can project anything on the iphone screen.
Enjoy.
I think this will be the last post on this subject since airplay was not working with my previous ergotech version 15.. Airplay now same as DLNA projection

including sound.
Amazing firmware. version. Works great.
For those asking if you can project netflix to a TV through Airplay hdmi dongle, no you cant due to HDCP hdmi protection (havent tested android) but you can project chrome for example. and videos played within browser. Chromecast hdmi dongle supports netflix is one solution but there are other too (smart TV). The problem for me is airplay support by these smart TVs which is not existent.
