iPhone says suport.apple.com/iphone/restore

Hello augusto185,

We are happy to help with your iPhone and the message you see on your display. The message you see specifies that you need to restore your iPhone. We'll use the steps from our resource here: If you see the Restore screen on your iPhone, iPad, or iPod touch - Apple Support

1. Connect your device to your computer using the cable that came with your device. Don't disconnect your device from your computer.

2. Restart your device:

• iPhone 8 or later: Press and quickly release the volume up button. Press and quickly release the volume down button. Press and hold the side button until you see the Apple logo.

Reinstall iOS or iPadOS

If you still see the Restore screen after you restart, you need to reinstall iOS:

1. On your Mac, make sure that you've installed the latest software updates (including iTunes if you have MacOS Mojave or earlier). Or on your Windows PC, make sure that you've installed the latest version of iTunes.

2. Make sure that your device is still connected to your computer. You should see this message: "There's a problem with the [your device name] that requires it to be updated or restored."

3. Click Update (not Restore) to reinstall iOS and keep your personal data. Don't disconnect your device from your computer until the update finishes.

If you have questions or concerns, reply back here.

Take care.
