Thank you for your summary!

I am a fresh user of an KC868-A16 REV:1.6 and your instructions save me a lot of time. Same as you, the first time I powered the unit the RF boards were installed and nothing worked until I removed them. As far as I could notice, no smell and no damage detected due to this.

Unfortunately in my case, WiFi AP is still not discoverable after step 5 of your sequence (power off/power on). Indeed, when the USB-C cable is plugged, from 5 to 5 seconds my PC beeps and the PCB's led quickly dims, ie, the unit appears to be disconecting/connecting (shoud I keep the USB-C cable unplugged?). This happens either with firmware KC868_16_V2.2.2.bin or the newer KC868_16_v.2.20.bin and with the USB-C cable plugged or not. I have not tried to access the board over the Ethernet.

Any additional hints, please?

Any help from the admin will also be welcomed!

Ehh, ok, finally figured this out, so I'll write a quick summary - hopefully someone will find it useful.
Brand new board, first power up:
1) Downloads:
USB driver firstly: https://www.kincony.com/download/CH341SER.zip
Firmware flash tool: https://www.kincony.com/wp-content/uploa..._3.9.2.zip
Latest firmware: https://www.kincony.com/forum/showthread.php?tid=3791
2) Install USB serial driver
3) Prepare board: if you have radio transmitter and received - remove it
Connect USB cable
Connect 12V power
4) Flash the firmware according to instructions:

5) Power down, power up the board. Clicking the reset button is NOT enough.
6) For me, after these steps, finally the AP appeared on list of WiFi networks and I could connect to http://192.168.4.1
