Hey there HallieCat26,
Do you still see the restore screen on your iPhone? If so, try taking the steps below first to get your iPhone back up and running:
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.
If you're unable to get past the restore screen, you'll want to reinstall iOS next, which will help by removing and reinstalling a fresh copy of the software on your iPhone. The steps below will show you how:
If you still see the Restore screen after you restart, you need to reinstall iOS or iPadOS:
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 or iPadOS and keep your personal data. Don't disconnect your device from your computer until the update finishes.
