Describe your issue:

hello, i can’t establish any connection to the printer in mainsail, the firmware-flash ran without errors, what makes me a bit suspicious is that the display still works after the flash. Mainsail always gives me “Klipper reports: SHUTDOWN” i dont know what i can do

Hello @auger !

Are you sure about this serial?

FileNotFoundError: [Errno 2] No such file or directory: '/dev/serial/by-id/usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0001-if00-port0'

You may reflash the board.

See MCU 'mcu' shutdown: Command request / Shutdown due to webhooks request
Your log does not look that bad, except you seem to like hitting the emergency stop button.

This can indeed be a legit serial. CP2102 is another USB to serial bridge chip just like the CH34x
