Hello everyone. I have wanted to get into flying UAVs for a while now as I'm a professional photographer and some of my clients have started asking for footage. Anyway, I figured since I already own a gopro 4, I would start to learn by getting an older Phantom to practice on and eventually spend the money on a new model. So I got a good used Phantom 1 and took it up a few times already, with great success. The seller suggested that I update the firmware as he hadn't flown it in a long time and that it might be a good idea. so I downloaded the NAZAM software and installed the latest firmware, which it seemed to take just fine. So today I wen to take up the Phantom for a fight and it won't boot. I turn on the remote control, plug in the battery on the drone, and I get the startup chirps, the lights blink through the different colors, and then it just flashes red and nothing happens. Obviously something is wrong. Any ideas on what I can do to fix this?
