iOS has gone to 12! Installing the update only requires a few steps . Normally, it should be a quick and easy process — but things can and do go wrong. If it times out, fails to verify, won't download, won't complete, or won't reboot, you'll need to troubleshoot. Here's what you can do!

What do you do if iOS 12 doesn't seem to be downloading or installing?

When you tap to install iOS 12, if nothing happens, you can try force-quitting Settings and begin again.

  1. Double click the Home button (or 3D Touch/firmly press the left side of the screen on iPhone 6s or later) to bring up the fast app switcher.
  2. Swipe across to the Settings app card.
  3. Kill the Settings Apps card by flicking it up and off the screen.

What if iOS 12 freezes or stops responding?

If your iPhone or iPad becomes non-responsive, hangs, or otherwise stops working, your next step is to force it to reboot.

On iPad, iPod touch, and any iPhone prior to iPhone 7:

  1. Press and hold down the On/Off button on the right side (iPhone 6 or later) or top (all other iPhones, iPods, and iPads) of your device.
  2. While continuing to hold the On/Off button, press and hold the Home button on the front of your iPhone, iPod touch, or iPad.
  3. Hold both buttons as the screen turns off, and keep holding them until the screen turns back on and displays the Apple logo.

On iPhone 7 and newer:

  1. Press and hold down the On/Off button on the right side.
  2. While continuing to hold the On/Off button, press and hold the volume down button on the left side of your iPhone.
  3. Hold both buttons as the screen turns off, and keep holding them until the screen turns back on and displays the Apple logo.

How about if iOS 12 won't restart or let you reboot?

If your iPhone or iPad doesn't want to shut down or start back up, you can escalate to recovery mode.

  1. Turn Off your iPhone, iPod touch, or iPad if it isn't off already.
