Can't find wifi after rear case replacement
I have changed the rear case of my iPhone 6 following this steps: iPhone 6 Rear Case Replacement
And now, when I finish, everything on my iPhone is ok, the camera, the bluetooth, GPS etc .. but the wifi does not find any network, it keeps looking and simply does not think.
What can it be? I was extremely careful, no screws were placed wrong, all parts were replaced correctly ...
