Have had my Phantom3 Pro for close to a year now never had issue.  Didnt fly it for a long while and just updated drone to most recent version with no problems. controller is at 1.2 and i cant get it to update (using usb stick)  Also now one of the front props wont spin at all when you try to take off.  I did fly drone maybe few months ago when both the drone and controller were both older versions.  Not sure if these issues are related. Any thoughts?  My ipad has newest version also now

You have to update the RC through the DJI GO APP......you can no longer do it through the usb.
Click on the upgrade message and follow the prompts.

Hello, adampalacios , first you need to update the remote firmware to 1.3.20 via the usb stick, after that , the remote need to update to latest version 1.6.0 via the DJI GO APP.
