Matrice 100: MC connection to center board failed. Gimbal cannot receive main controller signal

[kevin84]

Hi everyone,

I’m having a problem with my DJI Matrice 100 and was hoping someone here might be able to help. This occurred after failed firmware update using dji assistant 2 ,then after restarting the drone started beeping non stop and these errors appeared

Errors:

1. Main Controller connection to Center Board failed
2. Gimbal cannot receive Main Controller data

The Zenmuse Z3 still gives live feed, but it shows: “The firmware on the SD card is identical to or older than the current firmware on the device.”

The drone connects to my PC, but it does not appear in DJI Assistant 2 (v1.2.5 or v1.0.5). It’s also beeping nonstop from the gimbal.

I saw online that N1 Assist or M100Repair.exe might fix this issue. Is there any software available that could resolve it?

I would really appreciate any help or suggestions. Thank you in advance.
