I had the same thing happen to me back in February. With winter, I hadn't flown in around 2-3 months. I was getting that message and couldn't do anything. Finally after restarting a bunch of times, it went away. I am not a huge fan of updating firmware. I have had issues in the past.
Selling a Phantom 4 Pro. I am looking to upgrade. It wasn't flown that much. I am in Camden County NJ. I would prefer to sell face to face but would consider shipping.
Comes with original box, controller, 2 batteries, props
