Last Updated: February 19, 2024 Fact Checked

This wikiHow teaches you how to revert your iOS device to a previous version of software. Doing so will erase your iPhone's content and you won't be able to restore using a backup from your current operating system; additionally, Apple only permits downgrading your iOS for around a week after a new iOS version is released.

Things You Should Know
