FAQs on Downgrading iOS 26 to iOS 18

1. Is it possible to downgrade from iOS 26 to iOS 18?

Yes, it is possible to downgrade from iOS 26 to iOS 18, but only if Apple is still "signing" iOS 18. Once Apple stops signing an iOS version, downgrading becomes impossible through standard methods.

2. Can I downgrade iOS 26 to iOS 18 without a computer?

No, downgrading iOS typically requires a computer, either through iTunes, Finder (on macOS Catalina and later), or third-party software. The downgrade process involves installing firmware files, which is not possible on iOS alone.

3. Can I downgrade iOS without losing data?

Yes, but only if you have a backup before the downgrade. Downgrading iOS usually involves erasing all the data on your device, as the process replaces the current system version with an older one. To avoid data loss, you must back up your iPhone before starting the downgrade.

4. Can I downgrade to any iOS version?
