"No cellular reception, wifi just fine"에 답변I disconnected the battery and reconnect it back, the phone got signal without fully assembled. However, I got half blue and half red screen and then Apple logo which happened every a couple of minutes. I tried the same procedure and fully assembled the phone, it did not get the signal and showing searching.... Very strange... I saw there is a antenna coupler and tried to find replacement parts. Anyone know where to get it??
