Your iPhone 7 Plus won't update and you don't know what to do. Apple frequently releases new versions of iOS (your iPhone's operating system) to patch up software issues, so it can be incredibly when you can't get your iPhone to update. In this article, I'll show you what to do when your iPhone 7 Plus is not updating so you can fix the problem and install the latest software updates.

What's Really Going On With My iPhone 7 Plus?

At this point, we can't be certain why your iPhone 7 Plus won't update. A lot of the time, this problem is the result of a software issue. So while your iPhone isn't broken, there's something going wrong in the background.

Our step-by-step guide will help you walk you through the troubleshooting process, as well as show you how to update your iPhone 7 Plus in both iTunes and the Settings app. Sometimes, your iPhone 7 Plus will update in one but not the other, so we recommend that you try to do it both ways.

Without further ado, let's diagnose and fix the problem so you can install the latest iOS update onto your iPhone 7 Plus!

Turn Your iPhone Off And Back On

When you turn off your iPhone, the operating system shuts down all the little background programs that keep your iPhone running. When you turn your iPhone back on, all those little background programs start fresh, and sometimes that’s enough to fix a simple software glitch.

How Do I Turn My iPhone Off And Back On?

  1. Press and hold the power button (iPhones without Face ID) or the side button and either volume button (iPhones with Face ID) until "slide to power off" appears on the screen.
  2. Use your finger to swipe the red power icon across the screen from left to right.
  3. Wait for your iPhone to turn all the way off. This may take up to 30 seconds.
  4. To turn your iPhone on again, press and hold the power button (iPhones without Face ID) or side button (iPhones with Face ID) again until the Apple logo appears on the screen.
  5. Let go of the power button or side button and wait for your iPhone to turn on.

DFU Restore Your iPhone

A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if your iPhone is brand new, so the software problem may get solved.

Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.

Repair Your iPhone With Apple

Apple repairs iPhones at the Genius Bar in Apple Stores and through their online mail-in repair service. Apple repairs are high-quality, but out-of-warranty repairs can be much more expensive than third-party solutions. If you're looking to save some money you're not covered by Apple's warranty, you may want to check out our other recommendations.

How Do I Repair My iPhone With Apple?

How To Repair Your iPhone With Apple's Mail-In Service

  1. Visit Apple's support website to begin the online mail-in repair process.
  2. Alternatively, call 1-800-MY-APPLE (1-800-692-7753) to set up a repair.

How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

  1. Visit Apple's website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don't have an appointment, you may have to wait for hours or end up being turned away. (Editor's note: I'm a former Apple tech and we're not exaggerating — please, do yourself a favor and make an appointment first!)
  2. When you arrive, go to the Genius Bar to check in for your appointment.
  3. Genius Bar appointments always include free diagnosis. If you're under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you're not under warranty, the Genius will give you a quote for the cost of a repair.
