I tried that before, same result. tried it today and see picture for result
it looks that the SHA-256 comparison is failing

[admin]

it showed finished. it work well.

[Hendrik]

its not working, see the serial log after rebooting. after rebooting, and attaching a network cable, it never comes up, even i don't see it apearing in my router
even when i powered the unit, the green led on the ethernet port is on, and when i attach a network cable to it, its goiing off. then the orange one is blinking, but nothing happens

i received another kincony board yesterday, flashed it, and it works directly.
but hat one has a LAN8720 ethernet module while this one has a W5500

1: hold on the DW (download ) button.
2: power on for your KinCony S3 board.
3: remove your finger

then board will enter bootloader, you can download now.

1. S3 board MUST work with power supply, can you change to DC12V? can't only work with USB-C cable. the USB not power for the PCB.

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.

My replacement board have arrived.

I'm sorry to say that I can't connect to these either.

I have checked the voltages at R6 and R4 and also the S1 and S2 switches and all seem to be OK as per the schematic.

This is really frustrating. I am flash ESP32 dev board every day without issue.

What else can we check to get some firmware onto your boards. They are just not going into DFU mode.

[admin]

do you have a BIN file want to download to S3 board, if YES, you can post at here, i can have a test. your board we have tested then re send to you. i don't know why you can't download by USB-C.

[Hendrik]

This is my Bin file generated by esphome and flashed with esphome flasher and download tool.
compiled with esphome 2025.2
a minimal setup, only modbus is activated and a binairy sensor for the status
not able to upload a bin file, so compressed it to a zip file

There's no point in testing my bin file.

I still cannot get any of the four boards to connect to even try a bin file.

I upload to ESP32s every day without issue.

I have tried 3 different USB-C cables (all of which work with ESP32) and they do not work with your board.

I have tried every combination and sequence of power up, S1 press, S2 press, USB C connection sequence and nothing gets the boards connected.
