Good day, all.  Could anyone please provide a link to download the original P3S firmware?  I have one that won't fly, but the gimbal/camera work.  I have another (no cam/gimbal) that used to fly quite high, until I put the cam/gim on, used the app, upgraded firmware, then removed the gimbal.  NOW it won't fly over 100 feet or do.  I need to roll it back.  My email is slorid69 AT yahoo DOT com.  Thanks for your time, y'all.

Hey there - for firmware and hardware DJI subjects you'll need to post to DJI's main forum https://forum.dji.com/ or send them an email at Support@DJI.com.  This forum is for software development issues related to DJI's SDK.

Good luck!
