iphone restore and update

Hi dezog,

Thanks for coming to Apple Support Communities for help today.

From your description it sounds like you may have a forgotten passcode on the iPhone.

If you see "Unavailable" on screen, you should be able to follow these steps: How to remove your iPhone, iPad, or iPod touch passcode without a computer

"How to reset your device

If you're using an eSIM, contact your carrier before trying these steps and ask for a QR code to set up your eSIM again.

1. From your device's Lock Screen, try entering your passcode until the "[Device] Unavailable" screen appears and your device asks you to try again later. When you're able to, continue trying to enter your passcode until the "Security Lockout" screen appears and you get the Erase [Device] option in the bottom corner of the screen.
2. Tap Erase [Device], then tap Erase [Device] again to confirm.
3. Enter your Apple ID password to sign out of your Apple ID on your device.
4. Tap Erase [Device] to permanently delete all of your data and settings.
5. When your device restarts, follow the onscreen instructions to set up your device again, restore your data and settings from a backup, and set a new passcode.

You can only reach the "Security Lockout" screen if you previously enabled Find My on your device. If you can't follow these steps, you can use a computer to reset your device."

Have a fantastic day!
