Apple has rolled out an updated version of iOS 9.2.1 that allows users whose iPhones were bricked by “Error 53” to revitalize their iDevices. It caused phones whose home buttons had been replaced by third-party repair shops to fail a security validation.
“We apologize for any inconvenience, this was designed to be a factory test and was not intended to affect customers,” Apple told TechCrunch. “Customers who paid for an out-of-warranty replacement of their device based on this issue should contact AppleCare about a reimbursement.
The updated version of iOS 9.2.1 is a patched version, not a new version of the operating system. Also, the update doesn’t re-enable Touch ID. If you want to retain Touch ID functionality, you can get your home button replaced by Apple.
Apple has also updated its support document detailing Error 53 for iPhones.
