Experienced a crash due to improperly seated battery. The P3A starts up - leds, camera gimble - camera won't tilt via controller but does take pictures - when attempting to start motors I receved a "ESC error, resstrt aircraft, if that fails contact DJI support" - I did an IMU recalibration based on some internet searches - nothing changed all four motors will not start - any suggestions on what to check / is aircraft worth repairing?

Unfortunately when motors get obstructed during a crash, the excessive current can burn out the ESC controller circuitry on the main board.  It's usually a case of replacing the main board to get the drone in the air again.

I would 100% recommend contacting DJI / sending it in to DJI for inspection / repair estimate.

We're sorry to hear about your crash, since aircraft was damaged when crash, the best course would be send it in for repair.
May I know have you contacted our tech support to help you create a case and guide you to send it in?

Sorry we cannot see your photo, please click "Advanced"--"Picture", then upload the photo again.
Just to clarify, it shows "upgrade successfully"? right?
What is the led status on gimbal camera?
The remote can link to the aircraft properly?
