Dear Members, I installed the new firmware last night. Aircraft and Battery update. This one was a little tricky, normally after I update the firmware and it is successful the battery updates at the same time. Then I format the SD card to remove the new bin file. I believe this is suggested by DJI. The problem I ran into was when I changed batteries for my second flight the DJI GO app. Warned me my battery needed to be updated. I reinstalled the firmware to the aircraft and install my extra 3 batteries, they all updated successfully and then I formatted the SD card. All is good. Best Regards, William E Burrows Jr.
