FFS! Just upgraded to new firmware 1.3.0 on AC and then tried to do the same on RC. Now have flashing red light on RC and "RC encryption error" on the app - it upgrades to 1.3.2 on RC but every time I restart the RC I get the flashing red light. Surely this can't have fried my RC. (I attempted on my slave RC and it all works fine.) These RC units cost £500 - are you telling me that a firmware upgrade is capable of derailing one completely? DJI your products can really suck sometimes.
