I've had my Tello for 3 months. I got it after I broke my hip and not able to get outside to fly my mavic pro or spark. I have been flying the Tello around the house and never outside. Crash it a couple of times nothing serious. Today I was flying and went through 2 batteries like I always do. Charged the batteries and I all I get now is error 203. I had old firmware 01.04.35.01 so I updated it to 10.04.78.01. Still no help. Waited several hours for things to cool. Still no help. What do I do next with my new Tello brick? I have read other people have also had this issue. WONDERFUL!!!
