Apple's iPhone 6, 6S and 6S Plus owners, be careful if you want to repair your home button. Go to one of Apple stores or official partners. If you get it fixed outside, an error 53 will appear in your screen as soon as you update or restore your OS. Why? Well, because the phone and the home button (with fingerprint recognition) go together, and if you change one then the other detects it and leads your phone to nothing.
Do not worry. If face Error 53, you can either contact Apple or use an ios repair tool to fix your iPhone.
