Following the successful rollout of the iOS 9.3.1 operating system, tech giant Apple has announced that it will cease code signing for the iOS 9.2.1. This means that all devices that have opted to upgrade to iOS 9.3.1 cannot downgrade the operating system back to the older version.

Apple said that iOS 9.2.1 is already an obsolete version of its operating system, hence the decision to stop code signing. Apple noted that the newer iOS 9.3.1 offers a more secure platform for users since it includes the latest patches to fix reported bugs and security loopholes.

According to Apple Insider, Apple faced a couple of hurdles when it released the iOS 9.3.1 last week. Just hours after the roll out, iOS users started complaining about a bugged web link that causes some apps to freeze and crash.

Prior to the release of its latest operating system, security experts discovered a bloated associations file in the popular travel app Booking.com. The bug caused several apps like Messages, Mail and Safari to experience runtime failures. Reports indicate that the bug also affected a handful of third-party web browsers.

The data overflow brought about by the Booking.com bug prompted Apple to release a newer version of iOS since user reported the bug could not be fixed by simply uninstalling the app.

When Apple launched the iOS 9.3 in March, it caused an uproar coming from users of older Apple devices. The new operating system, when downloaded to older Apple device, caused devices to freeze and rendered them completely unusable. Apple responded to the problem by simply stopping the update from being rolled out on older iOS devices. The Cupertino-based company was able to release a patch that fixed the problem last week.

More recently, the flagship Apple iPhone 6s and iPhone 6s Plus were affected by a rather obscure security exploit that allowed malicious hackers to access user contact and photo data without providing the necessary passcode, according to Forbes. Apple was quick to response to the reported bug and fixed on April 5.
