PreArm Error: Unauthorized S/N and Compass Calibration Running

Hello everyone,

i copied some parameter to other Fixedwings because all are the same model (ZMO V2 VTOL).
After I doing so, I get while arming the Unauthorized S/N error and can’t arming. Also after FORMAT_VERSION = 0.
What can I do now, when I dont have the firmware to installing it new?

Also I get the error with commpas calibration running. But when I check, no calibration is running. Also after completing it, I still get these error. Please help.

Thank you!

You can’t copy all the parameters from one to another. Calibrations and S/N data is per individual unit. You’ll likely need to reset the affected models and start over.

What flight controller is it? You should be able to re-flash it from MP.

This is likely a custom message by the manufacturer. It is not something output by standard ArduPilot firmware. Contact the manufacturer for help to reset.

Sadly It’s a custom Firmware and I can’t choose it direly in Mission Planner. It’s a Neofly F407.

The OMHobby stopped after sales support for the ZMO and didn’t answer.

Is it possible to reflash the FC without the firmware?

So the Manufacturer will not help me because he dont produce the product anymore that I bought 5 month ago.

Anyone else know a solution?

There isn’t one. It’s custom OEM firmware for a board that doesn’t look to be otherwise supported.

Sure, replace the flight controller.

Which one you would choose for a 3 motor vtol? Inkl esc

TBS H7 Lucid Wing would be a good choice. What ESC’s do you have now?
