Remove/Uninstall iOS 26 Safely & Downgrade to iOS 18 [Super Easy]

Part 1: Before You Start Downgrade iOS 26 to 18: Important Things to Know

Thinking about switching back to iOS 18? You're not alone. Many users want to downgrade iOS 26 to 18 because their phones feel slow or buggy.

• Downgrading erases your data. So, make sure to back up your iPhone. You don’t want to lose your photos, messages, or apps.
• You can only install iOS 18 if Apple is still allowing it. That means the iOS 18 download must be “signed” by Apple. If not, the downgrade won’t work the usual way.

June 2025 Update: As of now, Apple is still signing iOS 18.5, which means you can downgrade from iOS 26 to iOS 18.5 without any issue—just follow the steps in this guide before Apple stops signing it.

• Downgrading is safe if you follow steps correctly, but don’t rush. Things can go wrong if you skip a step.
• Know your iOS 26 kind (beta or official)
• The newest version of iOS 18 (if signed) may be restored by simply deleting the beta profile if you're on the iOS 26 beta.
• If you're using the official iOS 26, the downgrade process is different and may require IPSW files and tools.

Looking for a safe and official way to downgrade iOS 26 to iOS 18? If you don’t want to rely on third-party tools, the most reliable method is using Apple’s built-in restore feature through Finder on Mac or iTunes on Windows.

• Restore your device

Once in recovery mode, a pop-up will appear on your computer saying there's a problem with your device. Choose Restore, then confirm by clicking Restore and Update.


• Download and install iOS 18

Your computer will now download the latest public iOS 18.5 firmware (around 8.5 GB), extract it, and begin restoring your device. This process includes erasing iOS 26 and installing a fresh copy of iOS 18.



If the device exits recovery mode during the download, simply re-enter recovery mode and the restore will continue.

• Finish setup after reboot
