Hello all I am having an issue that I can not seem to fix nor can I find any information online about.  I have a DJI F550 that I am trying to program.  When I hook up the hexa to the pc I am getting a Cfg err and it tells me this (Configuration error, this may be caused by firmware upgrade from the old version etc..  )

I Attempted to upgrade the firmware on this set up before I got this error.  The firmware upgrade failed however after the power cycle i noticed the firmware version is at what I tried upgrading to.  4.06

I am getting this CFG err and it will not allow me to do anything else.  Every time I attempt to downgrade or upgrade I get a failure.  

I have jumped f1 and f2 and connected it to the pc the firmware reads zero and it attempts to flash the upgrade but it returns with failed.  

Naza v2 is being recongized in the assistant when hooked up but I can not make any changes.  I can test my motors which they all spin however that is all I can do.

Anyone have any advice?
