Hi. My mini got crashed last new year (pilot error) and the front right arm broke. But it still fly when I glued the front right arm. And so I decided to replace it on my own and ordered a part online. After I changed it, now it won’t connect to RC. Already tried pairing mode by pressing the AC power button for 4 seconds with the RC and I also tried refreshing and downgrading the firmware through DJI Assist 2 and it still won’t connect. I also tried removing SD card and still problem exist. It seems the RC can’t detect the AC even if it is already turned on. Hope you could advise.
