Fly-away Mavic Air

[ECMA]

My mavic air, hovering at 12m (less than 1min into flight), decided to take off on its own.
I have line of sight of the drone.

Tried RTH button, joystick (elevation, yaw) movement, all failed.
No response from the drone.
Watched it crashed into trees.
Crashed, broken arm.

I had it repaired. Just got it back.
Powered on the drone without props (showed error 202).
Proceeded to update the firmware and recalibrate the sensors via laptop.
Once done, tested the joystick to make sure the motors are working fine.

At first all seems normal, then suddenly the motors sped up and errors started appearing.
These are similar symptoms I encountered when the drone crashed.

How do I investigate whether my drone is defective or not.
(Drone is grounded now).

Attached are the errors shown on the app.

Are those photos from the first crash? You took off with less than 50% battery?
You need to post flight logs for some of the guys here to give you an idea of what happened. Seems like it might have been magnetic interference prior to take off.

These images are from the latest testing conducted at home after I got the drone repaired.

Batt was less than 50% as I m calibrating the drone n testing to make sure I don’t get any errors. Does this has an impact why there motors suddenly sped up?

I will post the flight logs tonight.

I tested my 2nd Mavic Air at the same spot but didn’t encounter such issue (motor suddenly sped up) though it shows “Compass interference”.

Below are the flight records i manage to extract. Are these files correct?

Do that flight log is for when you powered it on without the props. Not the same issue as what might have caused the crash.
