DJI -- I have a drone that I wish to sell. I can no longer access with RC (drone is broken). How do I get it unbound from my account so that I can sell?

You dont need to unbind the M2P from you account,  it pre dates the binding process.  

Hi there,
thank you for reaching out.

As mentioned in reply #2, there is no need to bind and unbind the drone. You can simply hand it over to the new owner. They just need to create a DJI account and link the aircraft to the controller.

Feel free to contact us if you have any questions!

Thanks to you both. Much appreciated.
