Help needed!

[Andyovers]

So,I dropped my phone and broke the screen. No probs. injust replaced the screen-no problems. Only problem is I screwed in the wrong size screw in the wifi antenna and it snapped in the housing. I've managed to get the large screw in and the one on the left and the one next to the camera. However the other two have snapped in the housing. This is causing my wifi to be really really weak. I thin I need a new mother board to solve the prob. Anyone know where I can get a replacement one? 16gb on O2 uk

You may try ifixit for such part.
