iPhone 4, NO wifi & Bluetooth signal, NOT grayed out. Any solution?
I have a iPhone 4 GSM 8GB iOS 7.1.2. I had previously faced the "gray out" issue of WiFi/Bluetooth and I have gotten it fixed. Both WiFi and Bluetooth can be turned on/off now. WiFi's MAC address is displayed inside "Settings". 3G signal is functional.
(I have it fixed by removing and installing the same WiFi antenna several times...)
However, NO WiFi signal can be detected after I have fixed the "gray out", even if I put my iPhone near my router. Although bluetooth signal CAN be detected, it cannot connect or pair with any other devices. And it seems that the 3G signal has been weakened after I have fixed the "Gray out' issue.
AppleCare has expired.
I have been searching for solutions but none is yet helpful.
Any help or suggestions are very appreciated :D
