Diese Anleitung ist sehr schwierig und erfordert spezielles Werkzeug.

Do you have clear instructions and tools how to do it
So do you need to move the chip to replace the home button?
You need to reball or replace the chip to repair Touch ID.
If the home button or its flex cable is broken then it's completely shot, short of taking it to an Apple store for a replacement.
On the other hand, it could also be caused by the home button's extension flex cable running through the back of the lcd, and/or a damaged camera/speaker flex cable on top. So make sure to check all those out carefully before resorting to the Apple store.
After reading through a lot of suggestions, here's one which sounded interesting to me. Low and behold, this solution has actually worked!! I have removed that single screw completely, restarted the phone, and the home button started working perfectly.

I loosened the screw behind the center of the home button (holding it to the metal bracket), and it magically works now. This may not fix a lot of them, but it worked for me. I was just tightening that screw snug, but must have been too snug.
Very good points, it will certainly help people to resolve some of their problems, thanks for sharing your experience!
I hope you see this comment as I need to pick your brains, my iPhone 7 home button is none responsive, and obv the notification saying ‘Touch ID is not available’ keeps taunting me! Upon opening there is no obvious damage to the home button itself or the flex connected. However there is damage to one of the flex cables connected to the body of the phone itself. Do you know if this cable itself could be replaced therefore fixing the home button?? Any advice appreciated

@Daniel cox < It's not uncommon for a home buttons to go bad during screen replacement. The most common cause is a slightly torn ribbon cable attached to the button. Unfortunately there's nothing you can do about it, only Apple can replace it and sync a new button to the main board. As long as the home function work, just use a 6-digit code to lock it or none at all (like me lol). You could try to de-register the old finger print under Settings > Privacy > Finger Print, and try to register a new one. If it doesn't read your new print, it's defective. For those who have lost even the home functionality, now there's a special replacement home button available for about $15 (called the home button with home functionality) which as least restores the home function but not the finger print. When buying one of these new buttons, it's should be either in the description or the price is above $10/button. The old cheap ones around 3 bucks do not work. Good luck!
Is anyone else questioning this video? That IC chip is responsible for the home button click. Not the Touch ID. If you were to put it on a new home button and then try to use the new home button, you would be unable to use Touch ID.

I’m questioning the statement “This quide requires microsoldering and may not restore function to a new home button.”
Is the author making the obvious point that if the connections aren’t done properly the process won’t be successful, or funtionality may not be restored regardless?

The U10 chip is a capacitive touch controller responsible for the button press of the iPhone 7. It has nothing to do with touch ID which is self contained in the button. Replacing the button will invalid touch ID.
