Alarm sounds on DJI Go App after update firmware

[Russair]

I updated firmware on my P4. Now I get an alarm on the app. Is this normal? I had the props off while doing the update. Haven't tried to fly yet.

What kind of alarm?

Is it a constant woot woot?!? My start up sound changed. Not so loud any more and kind of fades with an echo. Weird.

You get an alarm when you start up the motors and give it some throttle when no props are attached on the P4 ,but if it was
that it also gives a message regarding a broken or missing prop.
