I crashed into a river but was able to recover the drone and dry it out successfully. Motors and camera power on without issue. I can still fly and take pictures and video, but there is no live feed to the tablet! I checked the SD card after blindly taking some pictures and video to confirm the camera was still working and it looks great. But I cannot see anything on the DJI app! Looks like this: What can I do to fix this? I've tried downgrading to an older firmware because I'd read a bit suggesting firmware issues can be at fault, but this video problem didn't occur until after the crash(and no firmware has updated since then) so it's safe to assume it had something to do with it. Thanks for any advice!
