Hi
Here is my problem. I have a 7.5" eink panel with the Xiao ESP32-C3 module in it. While looking for a firmware for it so I could use it easily with Home-Assistant, I made the mistake to flash it with a firmware for an ESP32-S3 
Now I’m unable to flash it back, in the flashing tool the serial port appears, then disappears then comes back all the time 
Even ESPConnect can’t connect to it anymore.
I tried also to reflash by holding first the button on the board but not better Did I kill it ?
I have tried to reflash it or check chip on it using ESPTool but it’s unable to communicate ! I have plugged the USB port while holding the Boot button on the Xiao but not better
Thanks
