Hello Guys !
I had a problem with an iPhone 7. Had no WiFi and no Bluetooth (grey buttons). After i change the Wifi ic, the Bluetooth is coming back the life. But the wifi is no... (gray button) I change another ic, 2nd the 3nd, but nothing change... I used every times a new ic. I checked al ic pads with multimeter in diode mode, every pads resistance value is ok. Any useful idea ?
