About 2.5 years ago I purchased my p3 pro. logged about an hour of flight time then put it away. Just recently pulled it back out and wanted to use it. Got funny warnings about software updates so I updated the Go app, controller and FW on the bird. FW crashed after 15 minutes along with steady beeps. Now it's a brick. Roll back of FW doesn't seem to work. Will not calibrate compass. Get warning on app of "No image transmission signal". Only thing I can do is move the gimbal using the remote. No camera display on either an Ipad mini or galaxy note tab. Repair service in NYC told me to use Assistant 2 to tether bird and update that way. Program doesn't even recognize the A/C. When I purchased this thing I also bought a second charger, 2 extra batteries, a set of ND filters, and a hard case. (which is was stored in, in the back of a closet. Sorry for the long rant, but it's been 4 days of utter frustration.
