I cannot update my iphone 11 to ios 15.7 or either 16, what should i do??

Hi safa127,

Welcome to Apple Support Communities. What happens when you try to update to iOS 15.7 or iOS 16? If there is an error message, what does it say? Are you using a computer or updating from your iPhone settings? These answers can isolate troubleshooting a bit.

Most of the errors and issues that you might encounter can be resolved using the guidance in If your iPhone or iPad won't update - Apple Support. Give those steps a try.

Take care.

When i try to update to ios 15.7 it says “an error occurred downloading ios 15.7”

i have been trying to delete “software update” from my storage too, but i tap on the delete option but it does not delete.

i have enough space for ios 16 too

but the “download and install” isnt showing!

idk what to do!. I have tried everything

The only error message is “update failed”, both for 15.7 update and 16 upgrade. I have 122GB storage and Cox GigaBlast internet, so neither are the problem. None of those are covered by the link posted.

And i am using iPhone settings to download it
