Dear DJI,

I have the dreaded ESC error and 4 red LED's flashing.

I have tried downgrading the software and re updating but still no change

I have tried other betteries and props, still no change

I've calibrated the IMEU and compass

What can I do other than sending it in for repair.

It's not following a crash

Hi Formy, sorry for the troubles with the ESC, may I know if the drone is Spark? What is the color of the LED?

The drone is the spark and all 4 LEDs are red.
