Ok want to share my experience with receiving a new battery today 8th feb 2017 and installing new firmware,. Note this is what i did not what i am saying is gospel..
1ST, before putting battery in phantom fully charged battery
2ND insert battery into phantom and turn on
3RD wait ot see if aircraft makes any noises or flashes any lights like it did when updating phantom aircraft firmware, waited 30-45 secs and aircraft was just as is normal when the remote is not turned on
4th turned on remote controller
5Th connected to phantoms WI-fi and opened DJI GO App
6th app told me firmware update for battery, - i pressed confirm and took about 1 minute give or take and job was done
note checked original battery just to make sure and original battery went into phantom switched everything on and app did NOT notify me of an update which confirmed that it just upodated new battery.
