Apple blocks iPhone users from downgrading to iOS 17.3.1

Apple stops signing old iOS versions to encourage users to update to the latest version to ensure security and optimize device performance.

It is known that on the night of March 5, Apple officially released the iOS 17.4 update, which is the fourth major update for iOS 17. After that, iPhone users were blocked from downgrading to iOS 17.3.1. Thus, if users update to the new iOS version, they will not be able to downgrade iOS to an older version.

This move is not surprising to iOS users as Apple often locks the signing of old iOS versions to prevent users from downgrading.

This is seen as part of Apple's efforts to help users update the latest features and ensure the security of their devices. Previously, the company also stopped signing iOS 17.3.

Currently, the latest official iOS version is iOS 17.4 with features such as: providing detailed iPhone battery status, adding many new emojis. At the same time, the 17.4 update also improves and fixes errors such as: Updating businesses in Messages for Business; Apple Cash virtual card numbers; supporting enhanced security options in locations; fixing problems in Find My.

Currently, iOS 17.4 version has gradually become more stable, causing less lag and unusual battery drain. You can update this software by going to Settings > General > Software Update.
