For example, my touch id stops working and I’m out of warranty coverage, does apple replaces the part and repograms the phone to the touch id sensor?
Yes, if they replace the display, the Touch ID button has to be replaced as well, they must have a way to reprogram it. From what I know, they will replace the display assembly (the entire front half of the phone) altogether if: the display is broken, the top sensors does not work, the receiver still does not work after replacing just the receiver, Home button/Touch ID does not work. The cost for OOW display replacement is around $100, if replacing the display doesn’t resolve the issue, they will replace the phone.
Ex-Genius here… Apple replace the entire display for Touch ID related issues. They use a “calibration” machine that pairs the new Touch ID to the logic board processor.
can the chip on the touch id cable that stores this key be reprogrammed? is it an eeprom? a uveprom? or is it non-reprogrammable, and simply a rom? I intend to figure this out.
Can apple fix touch id on an iphone 8 plus ?
When they replace the whole assembly. they transfer the Touch ID over from your old phone. thats why the design of the Touch ID is so easy to remove. Because the monkeys at apple need to transfer it over, yet somehow they manage to rip it. if that happens they will have to replace the phone for you for free! The Touch ID is serial coded to the logicboard. apple does this out of spike because they hate DIYers.
