No one in the software sections seems to know the procedure for reversing the last update V01.04.0602 and V1.4.1.0  I'd appreciate if someone here could help me.  I've spent the last 2 days on and off the forum spending hours trying to link my AC and RC, trying to update both of them and now when I finally have succeeded after aproximately 8 hours, I go out to fly and it says they are incompatible!  So now i've fixed that and now my gimbal is bobbing like an apple in a barrel!  Please someone could you please tell me how to reverse this?  I can't even seem to revert back to factory defaults.  It just sits there without doing anything.  I'm so glad I don't have clients this weekend!  I'm sorry for those who do.  DJI get your act together!  

At this point I believe the best option is to return this piece of junk to the place of purchase and get something supported by a company in the U.S.

Some similar threads (with the gimbal issue) have been resolved through doing a firmware refresh of the P4P using Assistant 2. Also, a refresh needs to be done with each battery you have installed in the craft, as the .0602 update also includes battery firmware.
