Hi,

I had a problem with my Samsung Galaxy S20 FE 4G, usb board, the usb port because of some unknow reason was melted and charging wasnt working,  i replaced it with a new one. After the successful replacement, now the usb is working as before but i saw one symbol, empty circle with slash and the connection to the mobile network is not working. I tred everything, both antennas are connected on the board, every connector is connected on the board. I also saw that Air Mode button is colored with light blue color, but Air Mode enabled mode is in darker blue color, does someone have an idea how can i fix this problem, or what is the problem?

Thanks
