Apple say 'error 53' will brick your iPhone 6
Are you an Apple customer, who has had repairs done to your iPhone on your screen or your home button? Have you then tried to upgrade your phone and got the 'Error 53' problem? Have you found that your phone has been bricked because of all this nonsense?
Well, this error is Apple's way of making sure that your phone's security hasn't been compromised... and as well as that, it seems to be their way of making sure an unauthorised third party haven't repaired your device too.
You might think that this all seems reasonable, but there is a problem here - should you be on holiday or whatever, and your phone breaks and there's no official Apple store around, if your phone breaks and you need it fixed, you'll be penalised. That doesn't seem too fair.
An Apple spokesperson says: "When an iPhone is serviced by an unauthorised repair provider, faulty screens or other invalid components that affect the Touch ID sensor could cause the check to fail if the pairing cannot be validated. With a subsequent update or restore, additional security checks result in an Error 53 being displayed."
"Without this unique pairing [betweeen the touch sensor and "secure enclave" in the phone], 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".
"We take customer security very seriously and Error 53 is the result of security checks designed to protect our customers. iOS checks that the Touch ID sensor in your iPhone or iPad correctly matches your device’s other components. If iOS finds a mismatch, the check fails and Touch ID, including for Apple Pay use, is disabled. This security measure is necessary to protect your device and prevent a fraudulent Touch ID sensor from being used. If a customer encounters Error 53, we encourage them to contact Apple Support."
So, if you're not able to get your phone fixed by an official Apple work, tough cheese, basically.
