Compass error mid flight after firmware update

[mkr]

When I think back a little bit? When I got to my apartment and updated it, I placed it in the box about 20 cm away from a 10 inch subwoofer after updating it.

Could the speakers magnetic field have magnetized it in some way?

I fixed it.
I first degaussed the compass by taking a magnet and turning it around the compass.
That didn't work.

Then i took a powerdrill and stuck the magnet on a drillbit and rotated the magnet around at the higest speed and moved that around the compass.

Aparently that is what did the trick as i have not had any compass errors since, and i usually had at least one every flight.

Do you have something on top of your drone, stickers etc.?

What do you mean by twisted the horizon what do you do with your sticks when it happens?

The Tilted/twisted horizon might be fixed with a IMU calibration. Make sure to do it on a completely flat surface and dont make it shake while the calibration is running.

This is best done while the drone is cold, preferably cooled to 15 degrees celcius.
Afterwards you should calibrate the gimbal on the same surface.

The lack of GPS signal however i don't know about.

And how degaussed the compass?

I don't think that is necessary, as it don't say anything about compass errors.
