note: if download failure. You can do these steps, let controller ESP32S3 enter BOOTLOAD again:
1. power off KinCony Controller.
2. hold on DW (ESP32 download button), don’t move your finger. (maybe “DW” or “DL” label on the shell)
3. power on of controller
4. release your finger.
5. Then controller enter bootloader mode. download firmware again.

@admin I'm a native French speaker and I also don't understand the messages, so the problem doesn't seem to be at your end... Thank you for the support you provide and your patience.
