During a recent firmware update using the most recent DJI assistant 2 software, the firmware update failed. Once DJI assistant 2 and the Matrice 600 pro was rebooted, I was unable to communicate with the Matrice 600 Pro when trying to connect through the USB port of the LED module. The only thing I can see through the DJI Assistant software is the Lightbridge 2. The LED module no longer lights up and I only get a continuous beeping eminating from the drone. Everything indicates that the A3 flight controller is completely bricked. Are there any steps to be taken to unlock the A3 flight controller without a complete replacement?

i am sorry to hear that .
