This absolutely fixed my wifi problem and the GPS triangulation problem. Phone working as good as new. Excellent instructions and thanks !

This fixed my problem. My wifi was extremely weak and my GPS would not triangulate. Same exact problem as others here described. I ordered the new antenna cable and followed these steps, and now phone signal is like new again I wouldn’t go through the trouble of writing this if I was BS anyone

Thanks for the detailed steps on how to complete this !
