I cannot restore or update my iphone using my laptop using itunes due to lack storage, however I cannot delete my files because my phone is not working

Hi nelissa1992,

Thanks for contacting Apple Support Communities!

We understand that your iPhone indicates you need to connect your iPhone to a computer to update or restore but you don't have enough storage available on your computer to do so.

If you've already restarted your iPhone and still see the same alert and you don't have access to a computer at home, you can visit your local Apple Store or Apple Authorized Service Provider to update or restore your iPhone. If you need help to locate an Apple Store or Apple Authorized Service Provider near you, you can visit this link: Find Locations

This article explains why you're seeing this alert and how to resolve it: If you see the Restore screen on your iPhone, iPad, or iPod touch - Apple Support

"Reinstall iOS or iPadOS

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."

Take care!
