No one found solution to my problem!

It's over 2 month since last time my wifi worked. All started after i dropped my iphone when i was away from home. Came back i tried to connect to wifi but i couln't. So i restored. Nothing. Still the same. Wifi greyed out, Bluetooth searching circle. Mac adress N/D.

Had same problem of this guy.

Wifi / bluetooth greyed out iPhone 6

I actually changed my antennas. Nothing, still the same.

I changed the Wifi IC Chip on the motherboard with a friend who's very good at electronics. Iphone turned on. Problem still the same. Can someone troubleshoot if we make mistake on putting back the wifi module on the motherboard?

If is like this, why the phone still turned on? Please help me out.. i don't want to bring it at local chinese store that want to charge me 150 euro. I changed everything of my iphone.

Screen x3 Times

Battery x2 Times

Charging port x1 Time

Camera module x1 Time

External Shell x2 time (nice colored ones :) )

If i will succesfully solve my problem, i'm gonna give 5 dollars to the guy who helped me successfully. Why? Spent:

15 euros on wifi module

12 euros on antennas

(Here in italy everything it's expensive i know. In america i could pay them few dollars.)

I don't have anything to lose, just using my 1GBxDay data plan. But i can't continue watch my netflix series from phone and youtube videos as well. And very ofter i arrive at half day without internet and without the possibility to connect to an Wifi.
