Can't connect to RC

My drone has been through a bit of a rough time recently. It’s still in one piece, but the gimbal rubber mounts have taken a bit of a beating. I’ve replaced them with new ones, but I’m still having trouble getting it to connect to my RC2. I’ve tried reinstalling the RC firmware and cleaning the cache, but nothing seems to work.

The drone started up just fine, passed the motors check, and the gimbal was calibrated. It was able to switch to pairing mode, and the Assistant 2 app detected the drone just fine. But then, when I tried to load the firmware list, the app just gave me a blank screen. So, I’ve gone ahead and tried reinstalling the drone firmware.

Can anyone suggest what else I could try to get the connection to the RC to work?
