It seems as if Apple has changed their tune with Error 53. They are now taking ownership for bricking devices worldwide.
Since the issue first came to surface, Apple has been stating that the problem has been because of repairs to the TouchID sensor that were done by “non-apple” repair centers. Upon IOS upgrade the device would go through a system check to ensure all components match, and if not, it would issue the Error 53 code.
According to TechCrunch, the security check was never intended to affect customers and was only meant to be used within its factories.
“We apologize for any inconvenience, this was designed to be a factory test and was not intended to affect customers. Customers who paid for an out-of-warranty replacement of their device based on this issue should contact AppleCare about a reimbursement.”
On Thursday Apple has released a patch to remedy the issue but did also mention that devices that have experienced the issue will no longer have TouchID available upon restore.
