Upgrading to a new iOS version is something many iPhone users eagerly await, as it usually brings exciting new features and enhancements. However, sometimes upgrading to a new version like iOS 17 doesn't feel right for everyone due to compatibility issues, bugs, or personal preferences. If you find yourself wanting to revert back to a previous iOS version, this detailed guide will help you understand the downgrade process step-by-step. Please note that downgrading can be risky and Apple may not always support it, so proceed with caution.

Preparation and consideration

Before we get into the process of downgrading from iOS 17 to an older version, there are several important things you should be aware of. Understanding these will help ensure that the process goes smoothly and you don't lose important data.

1. Back up your data

Downgrading iOS often involves completely erasing your device. This means that all data on your phone, including photos, contacts, and apps, will be lost during the process. To avoid permanent data loss, you should create a full backup of your device.

You can back up your device using iCloud or iTunes/Finder. Here's how:

Using iCloud

1. Make sure that your iPhone is connected to a Wi-Fi network.
2. Go to Settings > [your name] > iCloud > iCloud Backup.
3. Make sure iCloud backup is turned on.
4. Tap Back up now. Stay connected to your Wi-Fi network until the process is complete.

Using iTunes/Finder

1. Connect your iPhone to your computer.
2. Open iTunes (on Windows or macOS Mojave and earlier) or Finder (on macOS Catalina and later).
3. When your device appears, select it.
4. Now click on Back up.

2. Check compatibility and signing status

Apple only allows downgrading to certain iOS versions that are still "signed." Over time, Apple stops signing older versions of iOS to encourage users to update to the latest software. Before attempting to downgrade, verify that the OS version you want to downgrade to is still being signed by Apple. Use a website like ipsw.me to check the current signing status of iOS versions.

If the version you want to downgrade to is no longer signed, you won't be able to install it on your device unless you've saved SHSH2 blobs first, which is a more advanced process that requires planning before the upgrade.

3. Locate and download the correct IPSW file

IPSW files are firmware files used to install iOS on your device. To downgrade your iOS version, you must download the correct IPSW file for your specific device model. Make sure you are downloading from a reputable website that provides authentic Apple IPSW files. Again, ipsw.me is a reliable source for checking available firmware for Apple devices.

Once you've downloaded the appropriate IPSW file, you'll be ready to begin the downgrade process.

Downgrading iOS: Step-by-Step Process

Now that you are all set, you can begin the process of downgrading from iOS 17 to an older version. Follow these steps carefully:

1. Connect your device

Use a USB cable to connect your iPhone to the computer. Launch iTunes or Finder, depending on your operating system.

2. Enter DFU mode

To manually install the IPSW file, you need to put your device into DFU (Device Firmware Update) mode:

• For iPhone 8 and later:
  1. Quickly press and release the Volume Up button.
  2. Quickly press and release the Volume Down button.
  3. Press and hold the Side button until the screen goes black. Once the screen goes black, press and hold the Volume Down button while still holding the Side button.
  4. After about 5 seconds, release the Side button, but keep holding the Volume Down button until your device shows up in Finder or iTunes.
• For iPhone 7 and 7 Plus:
  1. Press and hold the Side (or Top) and Volume Down buttons simultaneously for about 8-10 seconds.
  2. Release the Side (or Top) button, but keep holding the Volume Down button until the device shows up in Finder or iTunes.
• For iPhone 6S and earlier, iPad, and iPod Touch:
  1. Press and hold the Home button and the Top (or Side) button simultaneously for about 8-10 seconds.
  2. Release the Top (or Side) button, but keep holding the Home button until the device appears in Finder or iTunes.

Note that if any logo or text appears on your iPhone's screen, you are not in DFU mode. It should remain completely black.

3. Install the downloaded IPSW file

Once your device is in DFU mode, you can begin the installation:

1. A message will appear in Finder or iTunes stating that your device is in recovery mode.
2. Hold down the Option key (Mac) or the Shift key (Windows) and click the Restore iPhone button.
3. A file browser window will appear. Go to the directory where you downloaded the IPSW file.
4. Select the correct IPSW file and click Open.
5. Finder or iTunes will now begin installing the iOS version from the IPSW file onto your device.

Wait for the process to complete: Your device will restart several times during the installation, and once the process is finished, it will be running on the older iOS version.

4. Restore your backup

After downgrading, your device will be set up as a new device. During the iOS setup process, you will have the option to restore from a backup. Select the backup you created previously to restore your data. You can restore from iCloud by logging into your iCloud account or from iTunes/Finder by connecting your device to a computer.

1. Complete the initial setup on your iPhone.
2. When prompted, choose the backup option Restore from iCloud Backup or Restore from iTunes Backup.
3. Follow the on-screen instructions to restore your data.

Troubleshooting potential problems

If you encounter any problems during the downgrade process, consider the following solutions:

1. DFU mode challenges

If entering DFU mode seems problematic, try the steps again. Timing and coordination with the key presses is important. Make sure you are holding down the right buttons for the right amount of time and release them in the specific order mentioned above.

2. Downgrade fails or errors occur

If the downgrade process fails or you receive an error message, try the following:

• Make sure your iTunes or Finder is updated to the latest version.
• Check if you downloaded the correct IPSW file for your specific device and iOS version.
• Restart your computer and try the process again.
• If connection problems persist, try a different USB cable or port.

Conclusion

Downgrading an iOS device can be a complex process that requires careful thought and preparation. Always make sure you back up important data before you begin, only proceed when Apple's signing window for the desired iOS version is open, and use authentic sources to download the necessary files. While the prospect of reverting to an older iOS version may seem appealing for various reasons, always consider the security risks and the lack of new features in the older OS version. This guide is meant to help you navigate the process with peace of mind and restore your device to the working state you desire.
