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 It caused phones whose home buttons had been replaced by third-party repair shops to fail a security validation.

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. The company has also updated its support document (https://support.apple.com/en-us/HT205628) detailing Error 53 for iPhones.
