Bought a used phantom a couple of days ago, it had only been used a couple of hours by the previous owner. It's 8 months old and hasn't been updated since. I tested it out and recorded some, and everything worked perfectly. My first issue was that I couldn't connect my phone to the remote with my DJI Go app(latest version). I tried iphone 5, iphone 6, ipad and samsung galaxy, no response on either(except charging). So i figured I need firmware update, so I updated the phantom to the latest firmware, and it went succesfull in the .txt file. Then I tried updating the RC, but I did not get any response from the remote on any of these methods: - USB flashdrive with latest .bin - SDcard with latest .bin - Connecting RC to gimbal input I then went outside to test it, but now the drone is only flashing yellow quickly, even after the warmup. So now I can't fly at all, the rotors wont start, but I can still record and steer the camera. I've been googling and trying to find a solution for 10+ hours but I'm close to giving up. Anyone knows a solution to my problems?
