Hey there,
My phantom 3 professional died when trying to update the firmware. I will take you through the process that I followed and the results. I've also attached the text log file.
I had not updated since version Packet: P3X_FW_V01.04.0010.bin since I bought the drone in August 2015. As you can see in the log txt file every time the firmware gets updated it has a lot of trouble. I decided to finally update it thinking a weak video signal issue may be fixed, it was getting the "no signal" issue maybe once every 10 times starting it up to fly. The RC updated to the new firmware first. I wasn't aware of the order of updating because it was listed at the very end of the directions on the DJI page. So the RC updated first through the App, and the "No Signal" became constant. I lost the ability to see the video feed. I could still control the camera. So I decided to the update the Dji Go App on my iPhone 6s which also has the newest iOS hoping to get the video feed back. No luck. Still "No Signal"
So then I decided to update the firmware on the aircraft. I searched on google until I found pretty detailed instructions on updating, they linked to the firmware on the DJI site for version v1.8.80. I downloaded it on my 2015 Macbook Pro running El Capitan 10.11, put it on the SD (first time was .bin and .pgcz because I archived it on Mac by accident). I made sure the RC was powered off, inserted the card into the Phantom, turned it on and let the update do it's thing. After 10 minutes of the proper beeping sequence, the front light went solid red and the Phantom went to a solid tone like a fire alarm. I powered down, checked the SD in the computer to see that the update failed. I tried several more times, but now it does not get passed 1 minute before the update fails and it goes to a solid tone. You can see this video here to know what happens :
I tried to downgrade the firmware to version v1.7.0060 via the DJI website instead, but the same failure occurs. After 1 minute it fails and goes solid fire alarm tone. So I did some more internet research to find there is a secret menu to downgrade the RC firmware. The downgrade was successful, but still I get "No Signal" when connecting to the aircraft. I can control it, control the camera, record video and take photos, but I cannot get a video signal. I tried loading the App on an Android device and get the same issue, No Signal.
I went back to google again and found that sometimes calibrating the IMU can help with the loss of signal, so I tried that with no luck. Still full control of the aircraft and camera but No Signal. I also tried using a different memory card, all cards I formatted in the phantom, with no luck. Still only makes it about 1 minute then fails with the solid red light and solid fire alarm tone.
So everything but the aircraft seems to be able to update. I can connect to the aircraft but have the 'No Signal' issue still. I tried reinstalling the DJI Go app a few times as a last ditch attempt. No difference.
Any help, ideas, guidance would be greatly appreciated! I only have 2 weeks left on my trip in Bali, Java, and Taiwan and I really want to fly

Reading the log and the 1.7 mentioned before that, my mind just skipped over the "RC" part. Apologies.
