The process of reverting an iPhone, iPad, or iPod touch to an earlier iteration of Apple’s operating system is a technical procedure. It often involves using a computer, specialized software, and a specific firmware file tailored to the device and intended iOS version. Successful completion results in the device running the selected, older system software.
There are several reasons individuals might undertake this action. Functionality issues with a newer operating system, compatibility problems with certain apps, or simply a preference for a past user interface are common motivations. Historically, this practice has allowed users to retain access to features no longer supported in later versions or to address performance degradation experienced after updating.
