Revert iPhone 12 to iOS 18 with These Simple Steps
Sometimes, upgrading to the latest iOS version doesn’t work out as planned. Whether it’s due to performance issues, app compatibility, or personal preferences, you might want to return to a previous version of iOS. If you’re using an iPhone 12 and want to go back to iOS 18, you’re not alone. While downgrading your iOS can be tricky, it’s completely doable if you follow the right steps.
In this guide, I’ll walk you through the process of downgrading from a newer iOS version back to iOS 18. By the end, you’ll know exactly what to do to get your iPhone 12 running smoothly on the desired version.
Why Downgrade to iOS 18?
There are several reasons why you might want to go back to iOS 18:
Performance Issues: Sometimes, new iOS updates can slow down older devices or cause unexpected bugs.
App Compatibility: Some apps might not work correctly on newer versions of iOS.
Familiarity: You might prefer the design and features of iOS 18 over newer updates.
Battery Life: If your battery drains faster on the newer version, downgrading can help.
Before starting, it’s important to note that Apple only allows downgrades to iOS versions that are still being signed. If iOS 18 is no longer signed, the downgrade process won’t work.
Step 1: Check If iOS 18 Is Still Signed
Apple only lets you install versions of iOS that are being signed. If iOS 18 is unsigned, you won’t be able to downgrade.
How to Check Signing Status:
Visit a website like ipsw.me, which tracks Apple’s signing status for all iOS versions.
Select your device model (iPhone 12).
Look for iOS 18 in the list of available firmware versions.
If it’s marked as “Signed,” you can proceed. If not, downgrading isn’t possible.
Step 2: Back Up Your Data
Downgrading will erase all the data on your iPhone, so it’s essential to back up your important files first.
How to Back Up:
iCloud Backup:
Open Settings > [Your Name] > iCloud > iCloud Backup.
Tap Back Up Now and wait for the process to complete.
Computer Backup:
Connect your iPhone to a computer with iTunes (Windows) or Finder (Mac).
Select your device and click Back Up Now.
Note: You won’t be able to restore backups made on a newer iOS version to iOS 18, so keep this in mind when proceeding.
Step 3: Download the iOS 18 IPSW File
To install iOS 18, you’ll need the correct IPSW (iPhone Software) file for your device.
How to Download the File:
Visit ipsw.me or another trusted source for IPSW files.
Select iPhone 12 as your device model.
Look for iOS 18 and download the IPSW file to your computer.
Make sure you choose the correct file for your iPhone model (e.g., iPhone 12, 12 Mini, or 12 Pro).
Step 4: Put Your iPhone in Recovery Mode
Recovery Mode allows you to install the older version of iOS on your device.
How to Enter Recovery Mode:
Connect your iPhone 12 to your computer using a Lightning cable.
For iPhone 12:
Press and quickly release the Volume Up button.
Press and quickly release the Volume Down button.
Hold the Side Button until you see the recovery mode screen.
Open iTunes (Windows) or Finder (Mac) on your computer. Your device should appear in recovery mode.
Step 5: Install iOS 18
With your iPhone in recovery mode, you can now install the iOS 18 IPSW file.
Steps to Install:
In iTunes or Finder, hold down the Option key (Mac) or Shift key (Windows) and click Restore iPhone.
Browse for the iOS 18 IPSW file you downloaded earlier and select it.
Confirm the installation and wait while your iPhone is restored to iOS 18.
This process might take some time, so be patient and don’t disconnect your device.
Step 6: Set Up Your iPhone
Once the installation is complete, your iPhone will restart. You’ll need to set it up again as if it’s a new device.
How to Set Up:
Follow the on-screen instructions to set up your language, region, and Wi-Fi network.
You can choose to set up your iPhone as new or restore a backup made on iOS 18 (if available).
If you backed up your data on a newer iOS version, you won’t be able to restore it after downgrading.
Step 7: Troubleshooting Common Issues
If you run into problems during the downgrade, here are some solutions:
Problem 1: iPhone Stuck in Recovery Mode
- Solution: Restart your iPhone by holding the Side Button and Volume Down button until the Apple logo appears.
Problem 2: Error Messages in iTunes/Finder
- Solution: Ensure you’re using the latest version of iTunes or macOS. Re-download the IPSW file if necessary.
Problem 3: Device Won’t Restore
- Solution: Double-check the signing status of iOS 18. If it’s no longer signed, the downgrade won’t work.
Tips for a Smooth Downgrade
Use Trusted Sources: Only download IPSW files from reliable websites like ipsw.me.
Charge Your Device: Ensure your iPhone has at least 50% battery before starting the process.
Double-Check Signing Status: Always confirm iOS 18 is still signed before attempting the downgrade.
Conclusion
Downgrading to iOS 18 on your iPhone 12 can be a lifesaver if you’re experiencing issues with a newer version. By checking the signing status, backing up your data, and following the steps to install the IPSW file, you can return to a familiar and stable iOS experience.
Remember, downgrading isn’t always possible, so act quickly if you’re considering it. With this guide, you’re equipped to handle the process smoothly and confidently.
