Flashing firmware

I’m trying to use esptool to download a backup of the tidbyt firmware for restore purposes. However, when trying to run esptool.py flash_id i’m getting wrong boot mode error. Does anyone know how to get the tidbyt into download mode ? I tried momentarily pressing the reset button and also holding the button on startup.

I understand I might be required to open up the unit and manually trigger download mode with a pin short somewhere.

It would be great if Tidbyt open-sourced the firmware code or at least provided downloadable firmware binaries.
