Hi all. Just got my first drone a P3A. DJI app says that the aircraft firmware version is the 1.1.9+ and RC firmware vesrion is the 1.2.6+ so I am going to upgrade to latest (1.4.0010). I am seeing that in between there are two more versions (1.2.8 and 1.3.20) and DJI site says that v1.4.0010 does not include remote controller update package and recommends users using firmware older than v1.3.20 to update the firmware to v1.3.20 before updating the aircraft. So my question is how do I upgrade? Step by step i.e. first upgrade both aircraft and RC to 1.2.8 then to 1.3.20 and finally to 1.4.0010 or am I going straight to 1.3.20 and then the aircraft only to 1.4.0010? Thanks any help in advance.
