How to Reset Your iPhone 8: A Step-by-Step Guide

Updated 2026-08-21 · 935 words

To reset an iPhone 8 without deleting data, force restart it by pressing Volume Up, pressing Volume Down, and holding the Side button until the Apple logo appears. To remove a forgotten passcode or return the iPhone 8 to factory settings, erase the device through recovery mode, Find My, or Settings, then restore a backup if one is available.

What should you know before you reset an iPhone 8?

The word “reset” can describe several different actions. Choose the option that matches the problem before continuing.

  • Soft reset or force restart: Restarts an unresponsive iPhone 8 without removing apps, photos, settings, or account information.
  • Device passcode reset: A forgotten lock-screen passcode generally cannot be recovered. Regaining access requires erasing the iPhone, which removes its data and settings.
  • Screen Time passcode reset: This changes only the code used for Screen Time restrictions. It does not erase the iPhone when the required Apple Account credentials are available.
  • Factory reset: Erases apps, photos, messages, accounts, settings, and other locally stored information.

If the iPhone still works, back it up before a factory reset. Also make sure you know the Apple Account email address and password associated with the device. Apple now uses “Apple Account” for the sign-in previously called an Apple ID.

How do you force restart an iPhone 8?

A force restart is the correct first step when an iPhone 8 is frozen, shows a black screen, or does not respond to touch. It does not erase personal data.

  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.
  4. Release the Side button when the Apple logo appears.

Perform the first two presses quickly. Keep holding the Side button even if the power-off slider appears.

This sequence is specific to the iPhone 8 and later button-based models. Do not use the older method of holding the Home and Side buttons together; that combination applies to some earlier iPhones.

How do you reset an iPhone 8 when you forgot the passcode?

If the lock-screen passcode is unknown, the iPhone 8 must normally be erased before it can be used again. Recovery mode works with a Mac or Windows computer.

  1. Turn off the iPhone 8.
  2. Connect a cable to the computer.
  3. While connecting the cable to the iPhone, hold the Side button.
  4. Keep holding the Side button until the recovery-mode screen appears.
  5. Open Finder on a Mac, or Apple Devices or iTunes on a compatible Windows computer.
  6. Select the iPhone and choose Restore when offered the choice between Update and Restore.
  7. Wait for the erase and software installation to finish, then complete setup.

If the software download takes long enough for the iPhone to leave recovery mode, let the download finish and repeat the recovery-mode steps.

Find My is another option when it was enabled before the passcode was forgotten. Open Find My on another signed-in Apple device, or use Apple’s Find Devices service, select the iPhone 8, and choose Erase This Device. The erase begins when the iPhone can connect to the internet. Apple Account credentials may still be required afterward because Activation Lock is not removed merely by erasing the phone.

How do you factory reset an iPhone 8 in Settings?

Use Settings when the iPhone 8 is responsive and you know its passcode. Before erasing it, create an iCloud or computer backup and confirm that important photos, contacts, messages, and authentication information are stored elsewhere.

  1. Open Settings.
  2. Select General.
  3. Select Transfer or Reset iPhone.
  4. Select Erase All Content and Settings.
  5. Review the information that will be removed, then select Continue.
  6. Enter the device passcode and Apple Account password if requested.
  7. Confirm the erase and wait for the setup screen to appear.

If the question is “how do you reset a iPhone 8” only because an app or screen is frozen, use a force restart instead. A factory reset is unnecessary unless you intend to remove all personal content or troubleshooting has reached that step.

What happens to your Apple Account and data after an iPhone 8 reset?

A factory reset removes locally stored apps, photos, messages, account sign-ins, saved settings, and the device passcode from the iPhone 8. It does not automatically delete information already stored in iCloud or another synced service.

During setup, sign in with the Apple Account previously associated with the iPhone. You can then restore from an iCloud backup or a backup stored on a computer. Data created after the latest backup may not return.

Erasing an iPhone through recovery mode does not automatically remove Activation Lock. If Find My was enabled, the associated Apple Account password may be required before the device can be activated again.

What should you do if an iPhone 8 reset does not work?

If Settings will not open, the passcode is unavailable, or the erase stalls, use recovery mode with a computer. Try a known-working cable, another computer port, and the current version of Finder, Apple Devices, or iTunes if the computer does not recognize the iPhone.

A reset may not solve a hardware problem. Seek device-specific help if the buttons do not respond, the computer never detects the iPhone, the screen remains blank after charging and a force restart, or the device repeatedly shuts down during restoration.

How can you get further help with an iPhone 8 reset?

Open {site} and choose the iPhone support area for official troubleshooting and service options. Have the iPhone model, Apple Account details, backup status, and a clear description of any screen message ready, but never share your password, device passcode, or verification code with another person.
