How to fix carrier issue in logic board in 8+
Hello, I changed back glass of iPhone 8 plus. after changing it, I have a new problem which says NO SERVICE (with “!” mark inside a triangle ). I cannot receive or make calls or access any data until i make an update. I checked it in apple support and it says there is a problem within, so i need to fix it. So, anyone please have details or a video how to fix No service from logic board? Thank you so much in advance. and I’m indeed eternal grateful to you.
Is this a good question?
