I swapped my good logic board with one that was iCloud locked from another phone both of these phones had perfectly working home buttons before hand but now my home button is unresponsive. It doesn’t click at all but Touch ID still works and it still can close apps. Any idea what the problem is?
Have you made sure you are using the same home button that came with the logic board?
iPhone 7 home button only with original home button can work normal, that is to say it will not work if you have change button. rewa has a video about the iPhone 7 home button repair with their customized charging flex cable.
