You have to update  EACH battery separately
***After updating the craft and the first battery
**Turn off the craft and insert new un updated battery
**Turn aircraft on and wait till DDDD changes to D...DD
**Turn off and go to the next battery
Each battery takes about two minutes i have 7 batteries

All three done!

are you noticing this for the Inspire only? Or does the same hold true for Phantom vision 2+ ?  I just did an update last night, then went to fly today and the battery level on one of my batteries went from 100% down to 10% within 2 minutes of flying and landed on it's own where it was. Could that be because that battery was not updated?

That's very helpful, thanks.

Ok so I have updated my controller and the Inspire itself. I have three batteries - I have followed the instructions and left the firmware on the SD card, inserted a battery and turned it on. Im getting the D--DD sound but its been going on for some time now. Is it going to re-do the Inspire firmware every time too or am I doing something wrong?

Please ignore my Sunday morning madness - Just realised I left the controller on!
