Hi, I had a problem. I would like to ask if you have not encountered this problem before. :
I flew in the mountains for about 10 minutes okay, I landed the drone or did not turn off and went about the location (I carried the drone in my hand) then flew to about 2 meters and I wanted to use the drone only as a tripod and take a picture with a panorama ... drone wrote AirCraftDisconect and told me that the land immediately immediately began to fall relatively quickly and landed in quite tall grass. I haven't connected it back to the controller since. I tried other cables even a brand new apple cable. I also tried to pair the driver again after unzipping I clicked on the button on the drone and nothing happened .... I thought of updating the firmware of the driver and drone so I connected the driver updated in order, connected the drone but the drone even though I connected according to the instructions to DJI ASSISTANT 2 just didn't want to connect or didn't show up in device manager. So I wanted to try connecting a drone via WIFI. I switched the switch, turned on the drone, looked at the wifi device on the mobile phone and no wifi was displayed. The next thing I noticed is that the LED next to the SD card just doesn't light up, it's just off. I just saw a mistake with that saltpeter, can the motherboard be damaged in any way? Thanks to everyone for all the advice.
Other cable tested (original fungl new apple cable)
the connector in the phone is clean
tested with another phone: iphone 6s plus, iphone 11 pro
