iPhone 7 - "The iPhone "iPhone" could not be updated. An unknown error occurred (14).
I know it's because of storage. I was in the process of deleting videos and photos when it crashed and went into a loop and couldn't restart. Is there a small recovery IOS I can download so that I can backup the phone then delete enough files to install the latest IOS? If not, can you create one or is there any IOS I can download or revert back to in order to backup all of my data? Thanks in advance.
