What happened is that I just got my new Phantom 3 Pro, (I know, that is the real Problem I'm a newbie) and my copy of DJI GO would not allow me to access the drone saying that I needed to update my firmware. So I went online and watched a number of firmware updates on You tube. They all showed using a Micro SD card and copying the Zip/Bin file, I had a new 64 Gig Micro SD card that I wanted to replace the standard 16 Gig card, so I thought great thats what I was going to do. However, after starting the upgrade I came across the PDF file from DJI on updating firmware. Reading it it says "You must use DJI GO to upgrade unless you have version 1.3.00 or earlier. Is that the truth? What can I do now? Can I use the old not upgraded 16 Gig card? If is doesn't upgrade can you start over? Thanks for any help. Im currently waiting to see if it will upgrade however, the front light is still flashing red.
