How to Downgrade from iOS 26.1 to iOS 26: A Step-by-Step Guide
So you updated your iPhone to iOS 26.1 and now wish you hadn’t. Perhaps due to faster battery drain, app crashes, or simply preferring the previous version, you might be able to go back—if Apple is still signing the older iOS 26 software. Here is how to do it safely.
⚠️ Important Note: Apple does not officially support downgrading from one public iOS release to an older one. The methods described involve technical workarounds, carry a risk of data loss, and only work if Apple is still signing the iOS 26 software. Once signing stops, downgrading becomes impossible.
📝 Essential Prerequisites Before You Start
Before attempting a downgrade, complete these mandatory steps to protect your data and ensure the process can proceed.
| Prerequisite | Details & Why It’s Important |
|---|---|
| 1. Complete Data Backup | Use iCloud, Finder (macOS), or iTunes (Windows). A backup is your only safeguard against total data loss. |
| 2. Disable Find My iPhone | This feature must be turned off. Go to Settings > [Your Name] > Find My > Find My iPhone and toggle it off. |
| 3. Download the Correct IPSW | Get the iOS 26 IPSW restore file for your exact iPhone model from a trusted source like ipsw.me. |
| 4. Prepare Your Computer | Ensure you have a reliable USB cable, a stable internet connection, and the latest version of iTunes (Windows) or Finder (macOS). |
⚙️ Method 1: Standard Restore via Finder/iTunes
This is the primary method for installing the older iOS file using your computer.
-
Connect your iPhone to your computer.
-
Open Finder (on macOS) or iTunes (on Windows).
-
Hold down a key and click Restore iPhone:
-
Mac: Hold the Option (⌥) key.
-
Windows: Hold the Shift key.
-
-
Navigate to and select the downloaded iOS 26 IPSW file.
-
Confirm you want to restore. The computer will wipe the device and install iOS 26.
-
Once complete, set up your iPhone as new or restore from a backup made before you installed iOS 26.1.
🔧 Method 2: Deep Restore Using DFU Mode
If the standard restore fails, use Device Firmware Update (DFU) mode. This is a deeper restore state that bypasses the current iOS version.
-
Connect your iPhone to the computer and open Finder/iTunes.
-
Enter DFU Mode (steps vary slightly by model; for iPhone with Face ID):
-
Quickly press Volume Up, then Volume Down.
-
Press and hold the Side button until the screen goes black.
-
Immediately, while still holding the Side button, press and hold the Volume Down button for 5 seconds.
-
Release the Side button but keep holding Volume Down for another 5 seconds. The screen should stay black.
-
-
If successful, Finder/iTunes will detect a device in recovery mode.
-
Hold the Option key (Mac) or Shift key (Windows) and click Restore.
-
Select the iOS 26 IPSW file and let the process complete.
💡 Final Warnings and Considerations
-
Backup Compatibility: You cannot restore a backup made on iOS 26.1 to a device running the older iOS 26. You must use a backup from before the iOS 26.1 update or set up the device as new.
-
Act Fast on Signing: Apple stops signing old versions (typically within weeks) to encourage updates and security. Check signing status on sites like ipsw.me.
-
Ultimate Solution: If the downgrade fails due to unsigned firmware or other issues, you may have to wait for a future iOS update from Apple to fix the problems you’re experiencing with iOS 26.1.
