WiFi greyed out iPhone 4S – iphone , badly help needed malfunctioning or other issue help please
Ive got an iPhone 4S from a customer, who said he had a greyed out WiFi and had an attempt to fix it, wich resulted in the iPhone not booting at all, even when on wall socket.
After looking at the schematics I gound out it was the wifi chip wich had a short.
After I replaced the wifi chip the iPhone would boot normally.
But I noticed that R49_RF and C13_RF had come off, and when the iPhone was put on the charger, the U5 chip would become veeeeery hot and the battery meassured 4,05volts.
After letting the iPhone rest for a day it would boot normally Along without getting very hot, but it now has greyed out wifi.
So my question is : are the missing R49_RF and C13_RF the cause of the greyed out wifi? And can I fix them?
