Today, Apple released an ‘update’ as intended specifically for fixing ‘Error 53’ which was controversially bricking iPhones that were repaired at unauthorized iPhone repair shops. This new update still is iOS 9.2.1 with a different bulid number: 13D20, the previous build was 13D15.
In order to resolve the matter, Apple specially issued an apologizing statement to TechCrunch.
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.
