iPhone6 generation customers have changed their shells. After installing, I found that the WiFi signal is very weak, suspecting that it is faulty, the other functions of the machine, only the WiFi signal is weak, the signal is weak, and some problems are received. If there is no WiFi general hardware problemMore, first check the receiving antenna passage, remove the detection
New back shell, but it is a brand new, very few new original rear shells
Remove the motherboard
Detect transmission matching line connection head break, this matching line is generally replaced
Replace new transport cable
The signal is full, the maintenance is over
More maintenance video and use skills, please pay attention to “Digital Madman Applefix” Thank you!
