How to fix your iPhone 7 Plus that is stuck on infinite boot loops after updating to iOS 11.3 (easy steps)

While this may not occur to all, other iPhone 7 Plus owners who recently upgraded to iOS 11.3 unfortunately ended up facing troubles as their iPhones were stuck on infinite boot loops and unable to complete the bootup process. Apparently, it is a software issue that might have been caused by a certain bug that’s triggered, if not contained by the new update. If you by any chance, you too have encountered a similar issue after installing the new iOS update on the same iPhone, then I have highlighted some generic solutions for you to try on. Try to perform these workarounds before you opting for service or other repair options.

Before going any further though, if you have other concerns with your new iPhone, make sure you drop by our iPhone 7 troubleshooting page for we have already started supporting the device. Moreover, if you need further assistance, you can always contact us by completing our iPhone issues questionnaire and providing us with sufficient information about the problem.

First solution: Force restart.

The very first workaround you should not miss is a force restart. This would help rectify software glitches inflicted by the update and eventually caused your phone to misbehave. This does not delete your data so you won’t lose any of your saved contents in the process. Here’s how it’s done:

  • Press and hold the Sleep/Wake (Power) and Volume Down buttons for about 20 seconds or until the Apple logo appears.

You may need to press the buttons a little longer as your device may likely not be able to boot up quickly as usual. If this won’t work, then try the next workaround.

Second solution: Charge then force restart.

The new update might have contained certain bugs that caused massive draining of power on your device and at the same time halting the boot-up process from completing. In this case, forcing your iPhone to restart while charging might be able to help. So here’s what you should do then:

  1. Connect your iPhone to a power source using the original (Apple-supplied) charger then let it charge for about 20 minutes. It should be good enough time for your device to accumulate power.
  2. After the elapsed time, force restart your iPhone 7 Plus by pressing on and holding the Sleep/Wake (Power) and Volume Down buttons for about 20 seconds or until the Apple logo appears.

If this doesn’t work either, then try the next method.

Third solution: Access your iPhone through iTunes on a computer.

Your last option would be to use iTunes. In order to get this done, you will need to secure a Windows PC or Mac computer with the latest version of iTunes software installed. And when everything is set, connect your phone to your computer using a Lightning cable.

If you are able to access your device through iTunes, back up your data and restore iOS. You can use a previous iOS backup file available or else, restore your iPhone system to its factory defaults and then set up your device as new. You can carry out iOS restore via recovery mode or DFU mode. Both these methods can be completed through iTunes.

To restore your iPhone 7 Plus in recovery mode, follow these steps:

  • Connect your iPhone to your computer using the supplied USB connector or Lightning cable.
  • Open iTunes on your computer. Make sure you are using the latest version of iTunes software.

While your iPhone is connected, perform a force restart with these steps:

  1. Press and hold the Power button and Volume Down button simultaneously until you see the Connect to iTunes screen. Do not release the buttons when you see the Apple logo because you will need to enter recovery mode first.
  2. You will then be prompted with the option to Restore or Update. To update your iPhone to the latest iOS version available, tap Update. Otherwise, select the option to Restore.
  3. Wait as iTunes attempts to reinstall iOS without erasing your data, and then download the software for your device. If the download takes more than 15 minutes, your phone will exit recovery mode. If this happens, let the download finish and then put your phone in recovery mode again using the same procedure.
  4. When the Update or Restore completes, set up your iPhone.

To restore your iPhone 7 Plus in DFU mode, follow these steps:

  1. Connect your iPhone to your computer using the supplied Lightning cable or USB connector.
  2. Press and hold the Power button and Volume Down button simultaneously for about 10 seconds.
  3. Release the Power button but keep holding the Volume Down button for 10 additional seconds.
  4. If your screen remains black after that, it means you’ve entered DFU mode already. But if you see any logo on the display, it means you haven’t entered DFU mode and that you will have to start all over.
  5. While in DFU mode, you should see a message saying that iTunes has detected an iPhone in recovery mode… At this point, you can proceed with iOS restore through iTunes.

To carry out the usual iTunes restore/factory reset, follow these steps:

  1. Open iTunes on your computer to get started.
  2. Connect your iPhone to your computer using the supplied a USB data cable or Lightning cable.
  3. Select your iPhone when it appears in iTunes. If you don’t see your iPhone in iTunes, unplug any USB accessories from your computer then restart your computer and reconnect your iPhone. Or if you have extra Lightning cables, try to replace the one you’re using.
  4. Select the option to Restore Backup in iTunes.
  5. Locate the backup file to restore from.
  6. Click Restore and wait for it to finish.

Keep your iPhone connected to the computer after it restarts and then wait for it to sync with your computer. After the syncing process, you can disconnect your iPhone.
