I repaired a broken screen by using the good screen from another iPhone SE... didn't bother to swap the TouchID so I get that error too, as all I really needed to do was get a working touchscreen to be able to sync entirely to another phone... Was dismayed to learn that I must have knocked off the filter capacitor by the battery connector because now this phone won't charge and it was already low due to the broken touchscreen preventing me from turning the phone off. :-( poor quality, unsustainable design, Apple! Shame on you.
