I've just fitted a new battery to my Phantom. The controller indicated that a firmware update was required. In fact it also indicated that a firmware update was required for the aircraft, too, which was not correct, since it had been updated only recently. I put the firmware file on the SD card and turned the machine on. Updating progressed as normal, as indicated by the sound signal and the camera LED. On conclusion, I turned it off and . reconnecting aircraft, RC and go app, the update warning is still there. I did have a look at the log file on the SD card, but the information there was not conclusive, since all entries had the same date and time (2014.01.01 00:00:11). Is there any way of getting the correct date and time on this?
