I deleted enough but still can’t install, the update

Hey there!

Thanks for reaching out to the community!

If I'm understanding you correctly, it seems you're having issues with iOS updates. I'd suggest checking this link for instructions on how to upgrade the iOS version on an iPhone with limited space: If you need more space for an update on your iPhone, iPad, or iPod touch - Apple Support

It may also be helpful to check out If your iPhone or iPad won't update - Apple Support

If all else fails, you can have your iPhone serviced at your local Apple Store or Apple Authorized Service provider. You can find your local Apple Store or AASP at Find Locations - Apple

I hope this helped!
