Copter crash

First i noticed that the modes spontaneously switch from loiter to 2D. I have several times used failsafe - suspension with the camera went crazy. 2-3 times i turn on failsafe, then tern on Loiter. As i remember, i can once switched on 2D myself, but in this mode turn the vector several times independently. Returned simultaneously with the reduction - forward and the gas at about 1/7. With 350-400 meters dropped to about 100. With this ALT under the start plase suddenly the copter started to shake and he fell. Flew up and dropped down to minimum throttle, zero is not set. Meters 50 gave full throttle - not react. What happened did not understand.
On the log periodically writes - more than 5 times - Gain knob rotated., I am sure that i did not touched at all. There are records near the end freefoll detected!!! multirotor stability issue, external bus error, vib too hi and then repeat this in a different order but without vibration.

Can anybody tell me, what is the cause of the crash? This is my third flight of the drone at all.

Hello,

In the screenshots you provided there is a warning of vibrations too high. This is likely the cause of the stability issue and the crash. Can you please open a support ticket and provide your log and config files?

Regards, John
