I just got my DJI Phantom 3 Pro, went through all of the videos, got everything charged up, and then started the Firmware Update process. I downloaded the file, copied it to the SD card, popped it back in the drone, and turned it on. The video wasn't so clear as to what the different beeps sound like and what they mean, but what happened was it was beeping like D-D-D-D...D-D-D-D, and they said it means it's "ready to update", then these other sounds started about every 2 minutes, it sounded like a "success" sound. Then the video said once the sound changes you have to manually turn it off and on. After hearing that success sound about 3 times, I figured it must be done and ready to restart. I turned it off and back on. The camera moved around, but no lights went on at all, the camera stabilized level, then this very loud and steady BEEP BEEP BEEP started, and it doesn't stop. No lights, just the annoying beep. I'm assuming this means it wasn't ready to restart. I took the SD card out, put it back in the computer, deleted everything off it, emptied the trash, put the firmware file back on, same thing. Loud annoying endless beep. Did this a few more times, took the battery out and put it back in, now I can't figure it out. DJI's 24/7 support hasn't helped this Saturday morning. Any help to get this working right is muchly appreciated!
