2. do you have hold on the S2 button on the photo?

right step is:

1. power off S3 board.
2. hold on S2 button (not release your finger)
3. power on S3 board.
4. release your finger.
5. connect USB-C cable to your computer.

Yes, I am using the correct button.

I have many similar devices. The boards are faulty.

The spec says 9-24V not 12V specifically. 9-24V See screenshot.

my means , you can test with DC12v power . if you have tried different usb-c cable also can't work.
tell us your order number, where you buy from, we will check then feedback to you. maybe need replace ESP32-S chip.

That is really great service from you and I appreciate it. My other Kincony boards are still excellent.

Please let me know by email when you have sent them.

Thank you.

do you have tested with our esphome yaml file? if can't work, can you take a video of your problem. so that can understand deeply.

yes, iam able to upload the compiled yaml file to the unit,flashing is goiing well (looks like)
compile the yaml file inside esphome, and then upload it with esphome-flasher (use this for al the units.)

after that, i disconnect the usb, restart the unit, with a ethernet calbe plugged in, but nothing happens, its not showing up in my router and even not in esphome.
i can see the orange led blinking on the ethernet port, green led is going off (this one is on when there is no cable inside, which is strange for me, as its not on other modules)

after uploading, nothing happens, even after waiting a long time, there will be no log. after restarting the unit, and i tried to connect it to see the logs, but the com port is showing and disappering, looks like if there is abad connection or something. even the serial conection cannot open

2. hold on S2 button (not release your finger)
3. power on S3 board.
4. release your finger.
5. connect USB-C cable to your computer.
