After updating my phantom 4 pro + firmware. my controller makes constant beeping sound and sometimes it dosen't link to my aircraft.
During my last flight, the LED lights went red, and controller started making beeping sound.
I am in Australia, and DJI dosen't have a service center in this country, or support center.
But my aircraft is in warranty. How do I repair my controller or receive a replacement?
Please help me.
This is the worst service experience I have ever had.

how long is this firmware update

This update is taking a full battery
