After replacing the battery in the iPhone 7, it popped up the window stating “Unable to activate Touch ID on this iPhone”. I thought I must have damaged the cabled to the screen and purchased this replacement assembly. However, after replacing and transferring the home button, I still get the same error. It’s not just touch ID, the home button itself does not register any touches. Does this mean the home button is toast? Without the home button, the phone is basically useless. I have double checked all the little cable connections and don’t see any problems. Any ideas?
