Hi,
I have been assigned the task of trying to get my company's Phantom 3 Advanced flying again after a crash several months ago.  After the crash one motor didn't want to work.  Now when I try to fly I'm getting a Warning "ESC Status Error.  Restart Aircraft..." and no reaction at all from the aircract.
Can you help?

Hi Zoppo, I am sorry to hear about the issue with your Phantom 3 Adv. As it experienced an accident, you may need to send the drone back for further diagnosis and service.
Please fill out the online repair request on our official web and send the drone back https://repair.dji.com/repair/index
