- Save the file to an easily accessible location on your computer.
Step 3: Enter Recovery Mode
To install the older firmware, your iPhone must be in recovery mode.
- Turn off your iPhone.
- Connect it to your computer while holding the appropriate button:
- iPhone 8 and later: Press and hold the Side button and Volume Down button simultaneously until the recovery mode screen appears.
- iPhone 7 series: Hold the Volume Down and Sleep/Wake buttons together.
- iPhone 6s and earlier: Press and hold the Home and Top (or Side) buttons.
Step 4: Restore iOS 17
With your iPhone in recovery mode, you can now restore the iOS 17 firmware.
- Open iTunes or Finder.
- A prompt will appear stating your device is in recovery mode.
- Hold the Option key (Mac) or Shift key (Windows) and click Restore iPhone.
- Select the downloaded iOS 17 IPSW file.
- Follow the on-screen instructions to complete the installation.
Step 5: Restore Your Backup
Once the downgrade is complete, restore your data.
- In iTunes or Finder, click Restore Backup.
- Choose the most recent backup and wait for the process to finish.
