I upgraded my P3P with firmware 1.2.6 and it is now being looked at by Dji. Okay my 2 batteries here with me also as I understand it, have been upgraded when they were flown in my bird with the installed 1.2.6 firmware. Some threads say leave the 1 bin file on the sd card so that the battery also upgrades as well. With all that explained, when I get my drone back will my sd card have the repair center's firmware bin file on it? And lets say it is firmware's bin file 1.1.9, will these batteries I now have downgrade, or reset...etc. (In other words is this something I need to look out for?) Thanks.
