      Hi,
      I have bricked a voxl in dev, trying to restore using the debug expansion, but the process fails:

      ~/Downloads/modalai-3-1-0$ sudo ./install.sh 
      [INFO] adb installed
      [INFO] fastboot installed
      
      This process will completely wipe your VOXL
      Would you like to preserve the /data/ partition which contains
      things like calibration, wifi config, and docker images
      To preserve files in /data/ answer Y
      To wipe /data/ for a full factory flash answer N
      
      Enter Y or N: 
      n

        Are you flipping the fastboot switch back? Your symptom is consistent with leaving the fastboot switch engaged instead of setting it back to normal after a few seconds

        Might be worth watching the tutorial here if you're unsure
