Member: 2045117 Status: Offline Thanks Meter: 7 | iPhone 6S No touch ID Also there appears no message about the TOUCH ID when I start the phone, only if I want to add a fingerprint it results directly in a failure. Can it possibly be U4040 ? (I'am not sure, because I have the possibility to add a fingerprint, but this will result directly into a failure). Hope someone can help |

Member: 2045117 Status: Offline Thanks Meter: 7 | SOLVED: Seems that some copy screens are not working with iOS 11 . I attached an origional LCD and restored the phone in DFU mode, now the touch ID is working. But if I switch over to the copy screen the TOUC ID isn't working anymore and only working on the origional LCD again after a full restore. I now used a Tianma LCD, assembly and the touch ID is fine |
