3DR Drone ends always loads up in "firmware update mode"

Hi - My 3DR in my drone keeps loading up in "firmware update mode" - (Solid Red LED).

What am I doing wrong? Simple Fix?

To get it to work, I have to connect it to flight planner and USB cable, and connect to it. Then update it, then plug it back in and it works once...

Thoughts?

Thanks

  • The red light will come on indicating update mode if the "Config" pin of the radio module is being held low or at ground during power up. Check to see if the cable is plugged in right and isn't damaged. Check this link if you already haven't looked at it:
