Unbricking fails due to "protocol error"



  • 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

    Would appreciate any insights and help I can get.


  • Dev Team

    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



  • Missed that part, thank you, it seems to do the trick.
