Apple s latest software update may not provide the experience some users expected. Performance issues, app compatibility problems, or personal preferences can lead iPhone users to consider switching back to an older iOS version.
If you want to downgrade from iOS 27 to iOS 26, following the correct steps can help reduce risks and protect your important data.
Prepare Your iPhone Before Downgrading
Before starting the downgrade process, users should complete a few important preparations.
First, you need access to a computer with iTunes on Windows or Finder on macOS Catalina and later. Older macOS versions require iTunes for device restoration.
Creating a backup is one of the most important steps. Users should back up their iPhone through iCloud or create a local backup on their computer to protect photos, apps, settings, and other personal data.
However, users should remember that iOS 27 backups cannot be restored on iOS 26. A backup created before upgrading to iOS 27 is required if you want to restore your device after downgrading.
You will also need the iOS 26 firmware (IPSW) file compatible with your specific iPhone model before beginning the restoration process.
Steps to Downgrade iOS 27 to iOS 26
To begin the downgrade, users need to restore their iPhone using recovery mode.
Enter Recovery Mode
Turn off your iPhone and restart it using the correct button combination. For Face ID models, press and release the volume up button, press and release the volume down button, then hold the side button until the recovery mode screen appears.
Connect iPhone to a Computer
Use a reliable USB cable to connect your device. A stable connection is important to prevent interruptions during the installation process.
Open Finder or iTunes
Launch Finder on newer macOS versions or iTunes on Windows and older macOS systems. Your iPhone should appear in the application.
Restore iOS 26 Firmware
Select the restore option and choose the downloaded iOS 26 IPSW file when prompted. During this process, the device will erase current data and install iOS 26. The restoration may take several minutes, so users should keep the computer connected to power and avoid disconnecting the iPhone.
Restore Your Data After Downgrading
Once iOS 26 is installed, users can restore their information using one of the following methods:
iCloud Backup: Sign in with your Apple ID during setup and select the backup created before upgrading to iOS 27.
Computer Backup: Connect the iPhone to Finder or iTunes and restore from a previously saved local backup.
iCloud Sync: Photos, messages, notes, and other synced data will return automatically after signing in.
Final Setup After Returning to iOS 26
After completing the downgrade, users should:
Set up Face ID or Touch ID again.
Sign back into apps that require authentication, such as banking and email applications.
Allow enough time for apps and files to fully restore.
Keeping the device connected to Wi-Fi during the restoration process can help speed up the recovery of apps and data.
Important Things to Know Before Downgrading
Users should keep several points in mind:
eSIM data: Your eSIM should remain available unless it is manually deleted during the process.
Future updates: You can upgrade back to iOS 27 later if you choose.
App compatibility: Some apps may require updates to work properly on iOS 26. By following these steps carefully, users can safely move from iOS 27 back to iOS 26 while minimizing the risk of losing important data and settings.
