I’ve just replaced my 7 plus’s screen: if i plug the home button in it will start boot looping and never make it to the home page . (on new screen) i plugged the home button back into the original screen, the screen wont light up at all but if i click the home button i can feel the tapic engine clicking. If i unplug the home button from the original screen the screen, the screen then lights up and works as normal I have pulled the front facing cam in and out and it doesnt seem to have any relevance to the issue.
You didn’t mention what happens with the replacement screen if you plug it in without the home button but I’d think it would be working, without bootlooping. If that’s the case, it seems both screens are working and home button is faulty, just delivering different issues with different connecting cables. Is it so ?
If you’re able to get another replacement screen, it could be the first replacement one is faulty. Happened to me once, boot looped and tried a second screen and it was fine. Same original flex cable and home button.
