Update firmware error

Hello friends, I have a seriously issue with the update of the firmware in my denon MCX 8000, I try to update the firmware of my controller like this manual says, but I get this message:

"Download error: Incomplete. Timeout

Display MCU Missing Control MCU Missing"

After several minutes waiting, I restart the controller, the controller try to update again the firmware, but get the same error.

Please help me and excuse me for my bad english.

Thank you.

You should try redownloading the firmware zip and use the included bin if possible.
