This week, Apple stopped signing four earlier updates it released. This means users who have already updated to the latest versions of their system will no longer be able to downgrade.
The updates that Apple stopped signing include iOS 17.0.3, iOS 16.7.1, iOS 16.7, and iOS 15.7.9. With this, users now running iOS 17.1, iOS 16.7.2, and iOS 15.8 on their iPhones are blocked from downgrading to earlier update versions.
Users usually downgrade to earlier versions of their OS to stop the occurrence of some bugs they received in the current version of an update. Fortunately, this seems not to be the case in the recent versions of the said updates from Apple. In iOS 17.1, the company even fixed 18 vulnerabilities. One includes a high-risk flaw that could lead to a passive device tracking via Wi-Fi MAC address. Other security issues in different areas of iOS that were addressed in this update include Weather, Siri, Photos, Passkeys, Mail Drafts, Find My, and Contacts.
