Unbricking fails due to "protocol error"

Nirge

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.

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.
