Still, not working, You made me look at the manual.
Inactive is when you have the remote on, and hasn't had a connection for 6 min to the Phantom.
It should also be beeping, to me you need to charge the battery.
This Manuel is so awesome.
I get frustrated every time.
It doesn't list your description, so I'm guessing it needs to charged, no sounds, no battery indicator?
It also doesn't state, what if has a connection to a mobile device, does it still time out because of no connection to the Phantom?
I believe it does, and you should have beeping noises.
#1 Does the remote beep, when you turn it on?
#2 What is the status link light button on the Phantom when they are both powered on?
#3 What was your method of updating the firmware on the remote?
