Gimbal roll error message

After a crash that broke the yaw arm and ribbon cable, I replaced both, and replaced the bent camera tilt motor too. Now, camera and gimbal do not move on start up or at all! I am getting a camera feed to the app, but camera and gimbal do not respond to any calibrations. I'm getting gimbal roll error message in app. Should i replace the entire gimbal camera as I've already replaced every part that was broke, or could this be inside the drone itself? I did remove top cover to inspect for any detached harness, but found nothing out of the ordinary.
