Wifi and bluetooth won't turn on

[JChang97]

Xperia Z2 (D6503)(Lollipop 5.0.2)(23.1.A.0.726)

Wifi and bluetooth won't turn on after I disable airplane mode after I woke up

I already tried rebooting, safe mode and factory reset but it still doesn't fix it

Any resolution?

You might want to repair the phone with PCC, but, make sure that it's a clean repair, which means it will delete everything

Try Contacting Sony Xperia Support.

Did PCC repair just now, everything clean and the problem still here. Wifi and bluetooth still won't turn on.

forever turning wi-fi on...

Wifi and bluetooth successfully worked for once but it can't connect to any network, then I can't turn it off anymore.

Contact Sony directly as it seems to be a hardware issue.

Hi,

I have had the same problem as you and it also happened for the Bluetooth.

Last week when I charged the phone fully after it was fully drained, it worked fine the next day. But after a few days, the problem occurred again. I did a back up and then factory reset. That didn't work at all.

Now I am planning to flash the Smartphone and see what happens.

Shall leave a feedback.

Thanks.

You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 80% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
