how can i get my home button replaced on iphone 7 plus
iPhone 7 Plus
Broke ribbon cable trying to replace cracked screen myself
Once you have opened the device on your own, or it is opened by a 3rd party repair, Apple will no longer support the device. You will need to try and find a competent 3rd party repair facility to try and fix your problem. Good luck. Next time you have a cracked screen, let Apple repair/replace it.
