All done now, like a breeze.
Was my very first upgrade ever, since 03/2014..
For the ones who wonder (like me) if they can upgrade their Aircraft from 1.1.9 straight to 1.4.0, here is what I did:
I used the "old" method, extracting the data to a SD card formatted in my PC in Fat32
Upgraded
just the controller to 1.3.2, not the aircraft.(Used a card reader plugged directly into the controller) Time 3mn.
Then extracted 1.4.0 to the same SD card (after reformatting in my pc in Fat32)
Upgraded the aircraft
straight from 1.1.9 to 1.4.0... Time 25mn as expected.
Then upgraded my 3 other batteries, by inserting them and restarting the aircraft with the SD card still in. (upgrade takes about 2 minutes per battery.
Turned off, removed the SD card.
Started the Ipad and went to the app store getting DJI Go 2.2.0
Started the whole thing, enabled multi flight mode, and I can see now the new features, everything is just fine, no message, no warning, just have to fly it now to see if all is ok. I'm sure it is.
Thanks.
