has anyone ever done a hard reset on their phantom vision 2, I was thinking about doing it to mine and install 3.08 firmware again, I saw on some videos on youtube how to do it and you have to put a jumper wire on the bottom pins of F1 & F2 but my question is there is a plug already on F1 do I just unplug the plug and then run the jumper wire from the bottom pins of F1 &F2....anyone know
