As a result: first I downloaded "
EVO II V1: V2.7.30 (Smart controller)". The remote was updated, but with an error. An inscription "roll back to the old version V2.7.25" appeared on the phone screen. I did everything, went outside, earned RTK. First "floating", then "fixed". I start to take off and one motor does not work. The drone does a somersault and that's it. Then I installed what you advised, everything was updated and all the motors started working. I didn’t check the RTK for operability, I’ll check it tomorrow.
