I read the wrong info and started to upgrade the Aircraft and RC. Downloaded the Firmware 1.9 and put on SD card, and installed in Camera. The launched the DJI Go App and hit upgrade and it upgraded the RC and Now no matter what I do I cannot get the Aircraft to upgrade. Thanks for any help.

Never mind found it.

The aircraft needs to be upgraded first then the remote. So, downgrade the remote and start fresh. Read the FW release notes.

You need to update or downgrade  the remote by using the DJI Go App
