I had the same problem last year with Lumia 520. Hard reset worked for me.

Got the exact same problem with my 950xl. It updated some sim-info today, and went into flightmode. Im on .29 and have just tried hard resetting it. Didnt help, so now I have a unuseable phone.

I have the same problem. It went into flight mode 5 days after purchase of using in dual sim mode. If I turn it off all indicators on the top bar are blinking and it looks like flight mode is continuously turning on and off like after pressed button on PC keyboard.
Phone is not usable.
I've downloaded all updates for now. No improvement. I’ve tried to reset. Not change.
