Here3 default bootloader

Is there a way to reset the bootloader on the Here3?

I mistakenly uploaded the Here2 bootloader on the Here3 and now it is showing HW Version 2.1 SW Version 1.7.3B7DB5CC under Mission Planner UAVCAN.

Not sure if this works:
Try to update the Here3 at UAVCAN and see if the Mission Planner can recognize and download the correct one.

Otherwise, you will need to RMA it

What is RMA?
