All those iPhone users that received an “error 53” message on their device after getting the home button replaced by a phone repair shop (that doesn’t happen to be Apple) are now going to be happy to know that Apple has issued an update for the error and apologized to those who have encountered that issue.
The new version of iOS 9.2.1 can be updated via iTunes, so just plug in your device and let the phone update. If it doesn’t power back on even after the update, then hit up your nearest Apple store and let them handle it. After all, that is what they’re there for. Apple stated that the error 53 message was “the result of security checks designed to protect our customers” but turned around today by saying it “was designed to be a factory test and was not intended to affect customers.”
Here’s Apple’s apology in case you were curious on what they had to say.
Some customers’ devices are showing ‘Connect to iTunes’ after attempting an iOS update or a restore from iTunes on a Mac or PC. This reports as an Error 53 in iTunes and appears when a device fails a security test. This test was designed to check whether Touch ID works properly before the device leaves the factory.
Today, Apple released a software update that allows customers who have encountered this error message to successfully restore their device using iTunes on a Mac or PC.
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.
Hopefully none of you guys ended up getting this error after getting your home button fixed, but if you have now you know what to do. Good job Apple.Source: Business Insider
