iPhone Unavailable on a Black Screen: What to Do

Updated 10 November 2026 · Standard formula, shown below

If your iPhone shows “iPhone Unavailable” on a black screen, it has disabled passcode entry after too many incorrect attempts; the black background does not necessarily mean the display is broken. You can usually regain access by using the on-screen reset option with your Apple Account, or by erasing the iPhone with a computer and setting it up again.

What “iPhone Unavailable” means

The unavailable message is a security lockout, not a diagnosis of screen damage. It commonly follows repeated incorrect passcode attempts, including accidental input or a passcode that someone has forgotten. The screen may be mostly black with white text, or the message may appear with an erase or recovery option. The wording and available controls can differ by iOS version and device state.

Repeatedly guessing is not a useful way to solve it. Further wrong attempts can extend the lockout, and the passcode cannot be recovered from the phone. An Apple Account password is not a substitute for the device passcode; it may instead be needed to authorize erasing the phone.

Try the on-screen erase option first

If the iPhone displays an option such as “Erase iPhone” or “Forgot Passcode?”, you may be able to reset it without a computer. This process deletes the data and settings on the device, so use it only if you accept that loss or have a backup to restore afterward.

Check that the iPhone has a Wi-Fi or cellular connection. The reset process may require a network connection.
Tap the erase or forgotten-passcode option shown on the lock screen. If it is not there, your iOS version or current state may not support this route.
Follow the prompts, confirm that you want to erase the iPhone, and enter the Apple Account password associated with the device if requested.
After the erase completes, follow the setup assistant. Choose to restore from an available iCloud or computer backup, or set up the iPhone as new.

Do not confuse an erase with unlocking: it removes the passcode by wiping the device, not by revealing or bypassing it. If you do not know the Apple Account credentials, recover access to that account through the official account-recovery process before proceeding where possible.

Use a computer if the on-screen option is missing

A Mac or Windows PC can restore an iPhone in recovery mode. This also erases its contents. Use a trusted computer with an internet connection, and make sure its operating system and device-management software are up to date enough to recognize the iPhone.

Turn off the iPhone. The button sequence varies by model: on many newer models, press and hold the side button with a volume button, then drag the power-off slider. If the screen does not respond, continue to the model-specific recovery instructions from Apple Support.
Connect the iPhone to the computer while holding the button used to enter recovery mode. For many models this is the side button; older models may use a Home button or a different button. Keep holding until the recovery-mode screen appears.
On a Mac, open Finder. On a Windows computer, open the Apple Devices app if available, or iTunes where that is the supported option. Select the iPhone when it appears.
Choose “Restore,” not “Update,” when prompted for a device that is unavailable or passcode-locked. A restore downloads software and erases the iPhone. If the download takes long enough for the phone to leave recovery mode, let the download finish and repeat the recovery-mode steps.
When the restore is complete, disconnect only when prompted, then set up the iPhone and restore a backup if one is available.

Button combinations depend on the iPhone model. If you are unsure which applies, look up the recovery-mode directions for that exact model rather than trying random combinations. If a computer will not detect the phone, try another cable or USB port, unlock the computer if needed, and check that the relevant Apple software is installed and current.

If the screen is black and nothing is readable

A truly blank screen is different from a black screen displaying “iPhone Unavailable.” First connect the phone to power and give it time to charge. Then try a force restart; it does not erase data. On many recent iPhones, quickly press and release Volume Up, quickly press and release Volume Down, then hold the side button until the Apple logo appears. Older models use different combinations, so check the steps for the specific model.

If the phone vibrates, rings, or is recognized by a computer but the display stays black, the display or another component may need service. If it shows the unavailable message after restarting, the passcode lockout remains and must be handled by erase and restore. A force restart alone does not remove the passcode or recover a disabled device.

Backups, Activation Lock, and what you can recover

Erasing removes locally stored data that has not been backed up. After setup, an iCloud backup may be offered if one exists; a computer backup can also be restored using the computer that holds it. Data that syncs separately through iCloud or another service may return after signing in and allowing synchronization, but this depends on what was enabled and when it last synced. A backup is not guaranteed simply because the phone used an Apple Account.

Activation Lock is a separate theft-prevention feature. After an erase, the iPhone may ask for the Apple Account previously linked to it. This is expected and cannot be removed by restoring the phone. If the device is yours but you cannot sign in, use the account-recovery options; for a secondhand phone, the previous owner generally needs to remove it from their account before you can activate it.

Common mistakes and when to get help

Continuing to guess: Stop entering passcodes if you are unsure. More attempts can prolong the lockout.
Expecting a restore to preserve data: Restoring a locked iPhone erases it. Check for a backup before starting if you can.
Choosing the wrong computer prompt: For a passcode-locked unavailable iPhone, “Restore” is the erase-and-reinstall path. “Update” is not a way to remove the passcode.
Assuming the black color proves a hardware fault: Read the exact message and distinguish a visible lockout screen from a completely unlit display.

Contact Apple Support or an authorized service provider if recovery mode repeatedly fails, the computer cannot recognize the device after basic cable and software checks, the display remains blank, or the buttons needed for recovery do not work. Service may address hardware problems, but it cannot retrieve data that was erased and never backed up.

Frequently Asked Questions

Can I fix “iPhone Unavailable” without erasing my iPhone?
No, not if the phone is locked and you do not know the correct passcode. The supported recovery options erase the device; afterward, you can restore data from a backup or resync data that was stored separately.

Does “iPhone Unavailable” mean my screen is broken?
Not by itself. If the message is visible, the phone is displaying a passcode lockout. A completely blank screen that stays blank after charging and a force restart may indicate a display or other hardware issue.

Can I unlock it with my Apple Account password?
The Apple Account password may authorize an on-screen erase or be needed after restoration, but it does not replace the iPhone passcode or unlock the existing data.

Will a force restart remove the unavailable message?
No. A force restart can help when the iPhone is frozen or its display is unresponsive, but it does not clear the passcode lockout. If the message returns, use an erase-and-restore method.

What if I do not have a computer?
If the lock screen offers an erase option and the iPhone can connect to a network, use that route. Otherwise, borrow a compatible computer or contact Apple Support for guidance on available service options.
