Discovering that your iPhone update did not go as planned can be stressful, but the process to undo an update on your iPhone is often straightforward if you act quickly. Whether the new software caused battery drain, app crashes, or connectivity issues, reverting to a previous version is possible with the right steps and preparation. This guide walks you through the entire workflow, from verifying compatibility to restoring your device safely.
Understanding iOS Downgrade Limitations
Before you begin, it is essential to understand that Apple only allows downgrades under specific conditions. Once Apple signs a newer version of iOS, it typically closes the signing window for older versions, which prevents direct rollback through standard updates. To undo an update on your iPhone successfully, you need to act while the older firmware is still signed, and you must have a saved copy of the IPSW file for your specific device model.
Preparing Your Device and Computer
Start by backing up your iPhone using iCloud or iTunes to ensure that none of your personal data is lost during the process. Connect your device to your computer, open Finder on macOS Catalina and later, or iTunes on earlier systems, and verify that the backup is complete. You should also download the correct IPSW file for your iPhone model and iOS version from a trusted source, as this file is necessary to initiate the downgrade process.
Gathering Required Tools and Files
A computer running the latest version of iTunes or Finder.
A trusted source for the appropriate IPSW file for your device.
Your iPhone charged above 50 percent to prevent interruptions.
A stable internet connection throughout the entire procedure.
Putting Your iPhone into Recovery Mode
To undo an update on your iPhone, you must place the device into recovery mode, which allows your computer to communicate directly with the bootloader. The steps vary slightly depending on the model, but generally involve pressing a combination of the Volume Up, Volume Down, and Side buttons in a specific sequence. Once the screen shows the recovery mode alert, your computer will recognize the device in an emergency state.
Step-by-Step for iPhone 8 and Later
Press and quickly release the Volume Up button.
Press and quickly release the Volume Down button.
Press and hold the Side button until the recovery mode screen appears.
Step-by-Step for iPhone 7 and 7 Plus
Press and hold the Volume Down button and the Side button together.
Hold them until the recovery mode screen is visible.
Release both buttons once the connect-to-iTunes icon shows up.
Restoring Using iTunes or Finder
With your iPhone in recovery mode, iTunes or Finder will prompt you to either update or restore your device. Select the option to restore, and then manually locate the IPSW file you downloaded earlier. Confirm the action and wait for the software to install the older iOS version. During this time, avoid disconnecting the device or interrupting the power supply, as this can lead to serious system damage.
Reactivating and Verifying the Downgrade
After the installation completes, your iPhone will restart, and you can proceed with the setup process. At this stage, you can choose to restore from your earlier backup to recover apps, photos, and personal settings. Verify that the downgrade was successful by checking the iOS version in Settings > General > About. If the version matches the one you intended to install, the undo update process is complete.
