this is going to help a lot for the people that fly in cold whether

The crash was intentional. Safety procedure when it came unresponsive(/unrecoverable). Fly low and let it crash.
By crashing it, it will prevent that it ever would go do things on it own and hurting people.

This update contains the important battery firmware update, please update and protect your drone battery from cold weather crash.

Does not look as intentional, it just dropped like a stone. All motors were shut. Either CSC (hard to imagine if a pro is piloting) or a soldering/battery issue?
