P3S about to be launched out the window. Switched on the P3S for the first time for 3 days, and a firmware upgrade is required. Downloaded via home wifi with no problem, but trying to update the controller and bird the upgrade reaches 40%, then the bird looses connection and starts beeping for over an hour. Had to turn the lot off and tried several more times with the same result. Finally dji go app shows firmware update failed. I restart all yet again, the firmware required banner has gone, go into camera view / settings and firmware shows up to date?. Anybody else have problems like this?
