I recently got the Mavic Mini from a trade for my race quad and I was very impressed given that I had a phantom 3 and mavic pro before.
After a few flights I turned it on and gave me a message the gimbal was stuck, I tried to clean the grains of sand, opened the shell to see if something was there and still nothing.
After some time I downgraded the firmware and started to work again, after a few days I upgraded and same thing happening. Did anyone have the same problem?
