Cannot find this in searches of forum subjects, Inspire 1 TB47 needs firware upgrade butwill not, I have formatted cards in our two Inpires with both our X5R and X3 camera, with the remote off and controller off and the upgrade sequence will not start for the battery at all. I have also tried different SD cards from 16GB to 64GB versions both Lexar and Sandisk,is there somnething i have missed?

Inspire 1A
Firmware - 1.7.00.90+
App- 3.1.38
RC-1.7.80
Camera X3- 1.10.01.40

Inspire 1 B
Firmware - 1.7.00.90+
App- 3.1.38
RC-1.7.80

Camera X5R- 1.10.1.40

Actually, the battery hasn't been requested to update for a long time, does the APP request to update the battery? Did the drone exit the travel mode? Did you copy the bin. file to the root directory of SD card?
