I updated the firmware in a hurry then someone called me so the DJI app exit. And when I try to hold down all the functions buttons it won't go in pairing mode :/

Try re flashing the firmware if your phone connects to the remote.

Hi, sorry for the inconvenience caused. Can you please try to refresh the firmware of your drone? After that, please try to manually re-link your RC to your AC. Thank you.
