iPhone 6P WIFI and Bluetooth Button Greyed out - HOME DIY FIX

We often see iPhone malfunctions like this on the forums, such as the iPhone 6P WIFI and Bluetooth Button Greyed out. In the comment section, many people expressed their helplessness. When their iPhone problem occurred, they sent it to the phone repair shop to fix it. But before long, the problem began to emerge, and no one knew a good way to solve it once and for all. today, The VIP Pro Shop Team will share some practical solutions.




Carefully disassemble the iPhone 6 Plus, check iPhone motherboard under the Trinocular Stereo Microscope, we found the iPhone WIFI module IC was gone, and the solder pad missing 6 points. In order to fix this issue, we weld the jump wire and then apply some green UV oil on it. After WIFI IC installation, test iPhone WIFI function, it works properly now. Continue to test iPhone Bluetooth function, it still not working.

Tear down iPhone WIFI module IC again, and then use multimeter to measure the diode date of solder pad, finding the diode data of tenth pin is OL, which is Bluetooth open signal BT_REG_ON. According WUXINJI Dongle, we know the BT_REG_ON is from the iPhone power iC, and through PCB board circuit to WIFI IC tenth pin, and then go to the PP3154_RF test point.


Now we're trying to knock it out on the pad, and then weld the jump wire, not exactly through the hole, we directly open WLAN_REG_ON from ninth pin WIFI IC and use QUICK 861DW Hot Air Rework Station to weld the jump wire, the purpose is to borrow the WiFi open signal.

After finish the above step, install the iPhone and get into IOS to test, now the WIFI and Bluetooth functions all works properly. No matter you open the WIFI and Bluetooth at the same time or separately, they all work perfectly.

Note:

Because the diode data of PP3154_RF is OL, so we can't weld the jump wire from PP3254_RF. If need weld the jump wire on it, we need to remove the iPhone power IC, and then weld jump wire from the middle of power IC, it's too time-consuming.
