My EVO I crashed into concrete from about 30 ft up. It hit hard and broke the camera but otherwise there's no obvious damage. However, the EVO won't power on except for the fan and a beeping noise. When I power up, it has a steady beep that soon changes to an alternating beep and then changes again to making a quick series of three beeps with the last beep sounding a slightly different tone. It continues to do that indefinitely. I disassembled it and could not find any loose or broken parts or cables and everything looked fine. I disconnected the camera cables in case they were shorting out because it should still fly even without the camera. I suspected maybe the firmware had gotten corrupt so I attempted to flash the firmware but it won't do that either. I contacted Alltel support and asked them what this meant and they just simply said to ship the drone back to them for repair. However, I'd love to be able to repair it myself if possible. I have an extra camera that I can use to repair the camera so the broken camera shouldn't be an issue for me. Does anyone know what the beeping means? Is there some kind of inertia switch that got triggered from the crash into the concrete that could be reset? Any ideas would be greatly appreciated. Thank you
