So, I tried updating my firmware from 1.4 via the DJI Go App and there were server issues this week. I'm afraid it may have caused problems with the firmware update as I now receive a "No Signal" in the app. It took many tries, but the app is reporting that the Aircraft is at version 1.6.00.40, the RC is at 1.5.70, and the camera is at 1.5.00.30. As I understand it, the camera should be at 1.6.00.40 as well. I tried updating again, but receive this in the text file. ========== 2016.01.23 10:45:55 ===================== Packet: WM610_FW_V01.06.00.40.bin Result: Failed. Reboot the aircraft and try to upgrade the firmware again. Any thoughts? Everytime I drop 1.6 on the SD card I get the D-D-D-D for a few followed by a long continuous tone.
