drone ctlr solid red, drone flashes quickly, slowly, then quickly

Controller lights are solid red when I turn it on. Didn't do that before. Should be blinking so that it is in sync mode.

Lights on Drone flash quickly. Then slowly ( as it should). Then within two seconds the lights flash quickly again.

It was working fine until that occured. Cannot get it to do anything different anymore.

I've tried all the basic troubleshooting which is useless. Why the controller is solid red when turned on I don't understand. It just decided to do that and it will not flash for sync.

Same with the drone. It just decided to do it's own thing as well.

Any thoughts?
