How to Factory Reset Your Phone

To factory reset your phone, use the erase option in Settings if you can unlock the device, or start the phone in recovery mode if you are locked out. A factory reset removes your personal data and settings, but it does not remove the account verification protections tied to the phone.

“Factory reset” means returning a phone’s software to its original setup state. Button names and recovery steps vary by manufacturer and model, so read the instructions for your device before confirming the reset.

When might you need to factory reset your phone?

You might need to factory reset your phone when a forgotten password or PIN prevents access, repeated software problems make the device unusable, or you are preparing to sell or give away the phone.

Try restarting the phone and installing available system updates before resetting a device that you can still unlock. A factory reset can fix some software problems, but it will not repair damaged hardware, a failing battery, or a broken screen.

If you forgot the screen lock, first try the official account or device-recovery options offered by the manufacturer. Resetting a locked phone normally erases its local data and may still require the previously linked Apple Account or Google Account during setup.

What should you do before a factory reset?

A factory reset deletes photos, messages, downloaded files, apps, saved settings, and other information stored only on the phone. Before resetting an accessible device, prepare for that loss.

1. Back up important photos, videos, contacts, messages, documents, and authenticator information to a trusted computer or cloud account.
2. Confirm that the backup completed and that you know how to access it from another device.
3. Write down the username and password for the Apple Account or Google Account connected to the phone. Make sure you can complete any required two-step verification.
4. Sign out of cloud and device accounts before transferring the phone to someone else. On an iPhone, turn off Find My when prompted; on Android, remove the Google Account through Settings.
5. Remove any physical SIM card and external memory card if the phone has them. An eSIM may need separate attention from your carrier.
6. Charge the phone and keep it connected to power during the reset.

Activation lock is a security feature that requires the previously associated account after a device is erased. Signing out correctly before giving away an accessible phone helps prevent the next user from encountering that lock.

How do you factory reset a phone from Settings?

If the phone is unlocked and responsive, resetting from Settings is usually the clearest method. Menu wording can differ by software version and manufacturer.

1. Open Settings.
2. On an iPhone, select General, then Transfer or Reset iPhone, then Erase All Content and Settings. On many Android phones, select System, Reset options, then Erase all data or Factory data reset. Samsung devices commonly place the option under General management, then Reset.
3. Read the list of accounts, apps, and data that will be removed.
4. Enter the screen passcode, PIN, or account password if requested.
5. Choose the final erase or reset command and confirm.
6. Leave the phone connected to power while it erases its data and restarts. Do not force it off during this process.

If your menu looks different, use the search field inside Settings for “reset” or “erase.” Select the full factory-data or all-content option, not Reset Network Settings or Reset All Settings, because those options do not completely erase the phone.

How do you factory reset your phone when locked out?

Recovery mode is a separate startup environment used for maintenance when the normal operating system or lock screen is unavailable. Entering recovery mode requires hardware buttons, but the exact combination depends on the phone model.

1. Connect the phone to power. For an iPhone, also have access to a Mac or Windows computer with the current Apple device-management software.
2. Turn off the phone if possible.
3. For many recent iPhones, connect the phone to the computer, quickly press Volume Up, quickly press Volume Down, then hold the Side button until the recovery-mode screen appears. Older iPhone models use different Home, Side, or Volume Down combinations.
4. On many Android phones, hold Power and Volume Down while the phone is off. Some models use Power and Volume Up or require a computer connection, so use the manufacturer’s instructions for the exact model if the recovery menu does not appear.
5. On Android, use the volume buttons to highlight Recovery Mode and the power button to select it. If an Android robot appears with “No command,” the device-specific button action is required to open the recovery menu.
6. Select Wipe data or Factory reset, confirm the deletion, and then select Reboot system now. On an iPhone, choose Restore on the connected computer when the recovery prompt appears.

A recovery-mode reset does not bypass activation lock. After the reset, the phone may require the Apple Account or Google Account that was previously connected to it.

What happens after the factory reset?

After a factory reset, the phone starts with an initial setup wizard. Choose the language and region, connect to Wi-Fi or cellular service, and follow the prompts for privacy, security, and account access.

1. Enter the previously linked Apple Account or Google Account if account verification appears.
2. Create a new screen passcode or PIN and record it securely.
3. Select the option to restore from a cloud or computer backup if you have one.
4. Wait for apps, photos, and messages to finish restoring before deciding that information is missing.
5. Install system updates and confirm that calling, messaging, account access, and important apps work.

If the phone is going to another person, stop at the welcome or language-selection screen after confirming that no previous-owner account prompt remains.

What should you do if the factory reset does not work?

If the phone is stuck on a logo or reset screen, keep it connected to power and allow time for the process to finish. If the screen does not change, force-restart the phone using the manufacturer’s model-specific button instructions, then try recovery mode again.

• If the reset option is greyed out, check for a work or school management profile, parental controls, or device restrictions. The organization or account administrator may need to remove the restriction.
• If recovery mode never appears, verify the model-specific button combination, cable, computer software, and charging connection.
• If account verification rejects your credentials, confirm that you are using the account previously linked to the device. Use the account provider’s official recovery process if you forgot the password.
• If the phone repeatedly restarts, displays an error, has damaged buttons, or cannot be detected by a computer, contact the device manufacturer, carrier, or an authorized repair provider.

Keep proof of ownership available when requesting help. Support may be able to diagnose the device, but security protections generally cannot be removed without valid account access or ownership verification.
