“Of course, it can only authenticate if Apple knows about your repair in advance, because you gave them the exact serial number of your iPhone, and they’ve pre-matched it to a display or battery.”
iFixit cut the iPhone 14 from a 7 to a 4 out of 10 a year after praising it. The hardware didn’t change. Apple’s parts pairing did the damage: a genuine screen or battery pulled from another phone fails until Apple’s servers bless it. Independent shops get a choice between sending Apple their customers’ data plus five years of audits, or leaving the business. A repairable phone that only Apple is allowed to repair is not repairable.
