Apple to customers who have had their phone repaired: “Enjoy Your Brick.”
Since iOS9 was released in September, there have been a major issue arising for owners of the iPhone 6 that have had their phones repaired. It seems that, unless the phone has been repaired or replaced by an Apple Retailer, it becomes bricked when the OS detects the repair.
A quick Google check gives over 150,000 results over this Error 53 issue. The main problem comes from when the phone is damaged and the fingerprint sensor on the home button needs to be replaced. The repair will work fine for a little bit until the phone updates, then the OS will detect the repair and disable the phone.
“We protect fingerprint data using a secure enclave, which is uniquely paired to the Touch ID sensor. When iPhone is serviced by an authorised Apple service provider or Apple retail store for changes that affect the touch ID sensor, the pairing is re-validated. This check ensures the device and the iOS features related to touch ID remain secure. Without this unique pairing, a malicious touch ID sensor could be substituted, thereby gaining access to the secure enclave. When iOS detects that the pairing fails, touch ID, including Apple Pay, is disabled so the device remains secure.”
So, gentle friends, hopefully, when you purchased your phone, you also received Apple Care. If you did not, and need your phone, take it to the closest Apple Retailer. Not because, as it used to be, this was the best choice, but because it is now your only choice.
