"Update to IOS 15.7.2: I am trying to update my IPhone 7 to IOS 15.7.2 but it keeps failing after downloading for sometime with a notification that an error occurred preventing the downloading to complete. What am I supposed to do in this case??? I have at least 100GB free space and an internet connection."

Update Using a Computer:

Have a Computer Handy? If so, try using a computer to update. See MY User Tip: Update your iPhone Using a Computer - User Tip. If any updates are available, they will install, sure enough.

Troubleshooting "Update Using a Computer"

I. Provide Two Things:

A. What is the Error Message?

A screenshot of the message would most certainly help. IMPORTANT: Leave of personal info, by covering it with red rectangles through use of the Photos app. Go Here: Take a Screenshot on your Mac - Apple Support

B. What's the Operating System?

If using a Mac, note that iTunes was discontinued in macOS Catalina. The TV app is for movies and TV shows, whereas the Music app is for music. Go here: What Happened to iTunes? - Apple Support

II. Performing the Update

A. Use a New Computer:

Try using a different computer to perform this update. Use a friend or family member's computer (with their permission, of course).

B. Boot in Safe Mode:

Try performing this in Safe Mode. See if it all now works. In Safe Mode, only necessary items load (i.e. the caches), and new preferences are set aside. Go Here: Start Up your Mac in Safe Mode - Apple Support

C. Create a New Administrator:

Create a new Administrator, seeing if you can then perform this. Go Here: How to Create a New Administrator Account on Mac OS - OSXDaily
