No service or very weak signal


I just replaced the home button on my iPhone 4. After i reassembled my iPhone I didn't have any service. When i go to the window in my room I get a very weak signal from a carrier but unfortunately not the right one. Can you help? I really miss my opportunity for texting.

Make sure you did not ruin the board when working on your device. Prying connectors not carefully enough may damage the connector or very small parts around it.

if you are certain that the logic board is ok, then try reconnecting the lower antenna cable, the black coax cable with a metal connector. if still not working, check the screw on the right end of the speaker. make sure there is a metal washer beneath the screw and the screw is properly tightened.

It works perfectly now. I reassembled it again again and then it worked. :-)
