Let me say this first... I don't want ANYONE telling me "this topic has been covered already" if so, reply with a link to the appropriate response. I also need details on exactly how to do everything as the DJI website is so wishy washy it's unreal. Just upgraded main controller to 3.06. While it was doing it, my phantom started bleeping and lights flashing red. When I left it bleeping, it seemed to turn in to 4 bleeps with lights flashing sporadically. Assistant software said it upgraded fine but when I power cycled, the motors don't start up. When it's stationary and turned on, theres a green light followed by 3 red flashing lights. I read the release notes and it says at the bottom to upgrade the controller before the central board. Don't know if I did this!! If anyone has a fix or has any CLEAR instructions on how to roll back the update with LINK TO THE FILES I NEED that would be much appreciated!!!! Thank you in advance for your non sarcastic/unhelpful responses.
