Is it possible to do a factory reset on the software for my Phantom 1, I seem to have gone round in circles, which is more than my quad, and I just can't get anything to happen I keep getting a message about tx calibration but can not make any sense of the instructions, I'm not tech minded !! Because it was purchased online the DJI tech help in Newcastle refuse to help under warranty terms as they say it wasn't purchased through official outlet? :evil:
