Australian regulator sues Apple for disabling iPhone, iPad units that received third party repairs16
The devices would run normally at first until they were updated to iOS 9. At that point, the affected iPhone and iPad units would stop working and show an "error 53" message. While Apple told owners of these so called "error 53" devices to contact them, some in the U.S. also contacted their lawyers and a class action suit was filed. The suit was subsequently thrown out of court. Eventually, Apple sent out a patch allowing affected iPhone and iPad models to update to iOS 9.2.1 by connecting to iTunes over a Mac or PC.
Apple admitted that the "error 53" message was designed to be a security check to protect Apple customers. When the components inside the Touch ID module don't match other components inside an iPhone or iPad, the Touch ID module is disabled. Many unauthorized third party repair firms could not match the components after a repair. Apparently, this violated Australian Consumer Law. As a result, the ACCC has gone to court and wants the judge to throw the book at Apple.
The regulatory agency is seeking injunctions, declarations, compliance program orders, corrective notices, other penalties and costs. Even though the story hit the media in early 2016 when the iPhone 6 and iPhone 6 Plus was involved, error 53 messages on iOS devices repaired by an unauthorized repair shop go back earlier than that. For its law suit, the ACCC says that its timeline covers the period from September 2014 through February 2016.
