If i downgrade phantom 3 standatd i must calibrate imu or not?

Hello oomichalekoo, it's not recommended to downgrade the firmware and it's better to calibrate IMU after upgrading.

After you upgraded both aircraft and remote successfully, you could delete APP and install it again.
Before flight, please make sure there is no or less interference around, such as buildings, WiFi, wires or metal.
During flight, please do not fly it above your head and try to fly farther then higher, or fly to other directions, such as East firstly then West.

Hello oomichalekoo, the aircraft will adjust itself automatically from the two certifications according to your location, we could not change it manually.
