When i power on my Phantom 4 Pro plus, the rear lights are solid red, and the motor seems to twitch a little bit. Anyone know why? all firmware is updated, and was flying it normally the other day. It seems like the drone is only connecting halfway with the controller?

Im new to this whole drone troubleshooting thing sorry if this is obvious

According to page 12 of  the manual ( https://dl.djicdn.com/downloads/ ... ser_Manual_v1.6.pdf ) solid red mean 'Critical error' …

If the remote is not connected, I would first try to link the remote ( see page 40 ) and go from there.

Hi, we're sorry for the inconvenience. I would like to ask if you're getting an error message in the application? Would it be possible if you could clarify to us if the drone experiences any incidents? You could check the status indicator using the image below. For additional information, if the drone indicates that it has a critical error, it's recommended to send the unit to our facility for further evaluation.
