Apple warns that the replacing Touch ID home button on iPhone 6 by the unauthorized technician, causes a major issue: you won’t be able to update or restore to the latest iOS 9, according to the report from The Guardian. The ‘error 53’ will appear if you try to update or restore it through iTunes on your Mac/PC. It happens because of the genuine detection from Touch ID home button or cable that connects it during the update or restore process. If the part was replaced by the unauthorized technician, the process will be stopped and the ‘error 53’ message will appear.
If this thing happens, iPhone 6 will face the update or restore failure continuously. Moreover, you cannot use that iPhone at all and it will be in the recovery mode condition. Regarding ‘error 53’. iFixit reported that the number of users who face this issue is many and there is no way out for them.
“The ‘error 53’ page on our website has had more than 183,000 hits, suggesting this is a big problem for Apple users. The problem occurs if the repairer changes the home button or the cable. Following the software upgrade the phone in effect checks to make sure it is still using the original components, and if it isn’t, it simply locks out the phone. There is no warning, and there’s no way that I know of to bring it back to life.”
Apple explained this issue in detail and suggested the users to consult the authorized service provider.
“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. 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 … If a customer encounters an unrecoverable error 53, we recommend contacting Apple support.”
If you are planning to replace your iPhone 6 LCD in the unauthorized service provider, make sure the Touch ID home button is still the original one.
