So... how does this work as far as error 53 goes? I'm currently on ios 9.2, and cracked my home button. It still works, but it bothers me that it's cracked, however I don't really want to brick my phone in the process. Do I need to be on 9.3 before I replace the home button? Or does it not matter anymore? I'm kinda lost as far as that goes. Any help is greatly appreciated. Thank You.
