If you see error 53 or can‘t update or restore your iPhone or iPad , it means your iPhone may gets bricked , and you loose the iPhone.
So what is this Error 53 :
“Error 53,” as it’s known, has affected potentially thousands of iPhone 6 owners, The Guardian reports, saying that the error completely bricks (i.e. to render inert) your smartphone beyond repair.
The error occurs with iPhones that have their Touch ID sensor, which allow users to unlock their phone with a fingerprint, replaced by some third-party repair services. However, some users have reported that even replacing a cracked screen can trigger the error.
Finally Apple has apologized to users whose Bhone bricked and gave a solution on the Site :
If your iOS device has Touch ID, iOS checks that the Touch ID sensor matches your device’s other components during an update or restore. This check keeps your device and the iOS features related to Touch ID secure.
When iOS finds an unidentified or unexpected Touch ID module, the check fails. For example, an unauthorized or faulty screen replacement could cause the check to fail.
If the check on Touch ID fails, your update won’t finish. You’ll see a Connect to iTunes screen on your device or a message like this in iTunes on your computer: The iPhone [device name] could not be restored. An unknown error occurred (53).
Follow these steps
- Make sure that you have the latest version of iTunes.
- Force restart your device.
- Try to restore your device again.
- If you still see error 53 when you try to restore your device, contact Apple Support. If the restore won’t finish and you see a different error code, learn what to do.
If the screen on your iPhone or iPad was replaced at an Apple Service Center, Apple Store, or Apple Authorized Service Provider, contact Apple Support. If the screen or any other part on your iPhone or iPad was replaced somewhere else, contact Apple Support about pricing information for out-of-warranty repairs.
