How to fix an iPhone 8 that is stuck on black screen with odd notification lights after an iOS update (easy steps)

Nonetheless, don’t fret yet as you still can do something or try some workarounds to fix the problem and get your device back up and running smoothly again.

How to fix your iPhone 8 with black screen of death issue

The following walkthroughs are intended for anyone who just installed the latest iOS update on their iPhone 8 and unfortunately ended up having an iPhone that is stuck on black screen or other unusual behaviours.

First solution: Force your iPhone to restart.

This is the first recommended solution to try on whenever you encounter software-related problems as depicted by a frozen display or stuck on black screen. It is a simulated-battery removal procedure that works similar to a soft reset but carried out using hardware key combos. And like a soft reset, a force restart will likewise fix software problems and errors without affecting your iPhone data. If you haven’t done it yet, then do so with these steps:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side/Power button until the Apple logo appears.

You may have to press the buttons a little longer like 20 seconds or more until your iPhone system is boots up.

Second solution: Force restart while charging.

Your iPhone may also be stuck on the same state if certain apps have gone rogue and consumed massive amount of power on your device. It’s possible that any of your apps gets corrupted or infiltrated by some malware that eventually affect the iPhone’s system functions. As possible solution, try to plug in your iPhone to the charger and let it charge for about 15 minutes. After the elapsed charging time, force your iPhone to restart using the same steps demonstrated in the previous method. Doing so can help eliminate any glitches as it refreshes all your apps and iPhone system in general.

Third solution: Connect your iPhone to a computer and use iTunes.

The next possible solution you can try on if the previous methods failed to offer a resolution is iTunes. You can use iTunes and attempt to access your iPhone system on a computer then carry out system resets and restore, if necessary. Be sure to use the latest version of iTunes software to avoid system conflicts.

If your iPhone is recognized in iTunes back up all your important data to iCloud or to iTunes drive on your computer. After you’ve created necessary backups, restore your iPhone to factory defaults (factory reset), restore in recovery mode or go for a DFU mode restore using iTunes. These restore methods are usually required to fix major system bugs from the latest iOS update that might have caused your device to get stuck on black screen and execute some unusual actions. You may opt to start from the standard iOS restore to wipe your device and set it up as new or jump into a more advanced resolution. You may then try restoring your iPhone 8 and set it up as new with these steps:

  1. While your iPhone is connected and recognized in iTunes, click the option to Restore iPhone to factory defaults.
  2. If you want to downgrade or restore to a previous iOS backup file, you may do so by clicking on the Restore Backup in iTunes button and then select the iOS backup file you want to use.
  3. You may refer to the date and size of each backup and choose the most relevant.
  4. Finally click the Restore button and wait for the restore to complete.
  5. If prompted, enter the correct password for all your encrypted backups.
  6. When the restore is finished, your iPhone will reboot automatically.

Be sure to keep your iPhone connected to your computer after it reboots and wait for it to sync with your computer. After the sync is completed, you may disconnect your iPhone from your computer.

If you find the need to perform a recovery mode restore through iTunes, then you may do so by connecting your iPhone to your computer with the supplied USB cable then open iTunes first. With your iPhone connected and recognized in iTunes, force it to restart with these steps:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side/Power button when you see the Connect to iTunes screen. Do not release the buttons when you see the Apple logo since you’ll need to enter recovery mode.
  4. On the next screen, you should see the option to Restore or Update.
  5. Select Update first to update iOS. Otherwise, select the option to Restore. iTunes will then attempt to reinstall iOS without erasing your iPhone data and then downloads the software for your device.
  6. If the download time takes longer than 15 minutes, your device exits the Connect to iTunes screen. If this occurs, just wait until the download is complete then go back to the previous steps to enter recovery mode again.

If the problem persists, then you can try a DFU mode restore. A DFU mode restore is regarded as the most in-depth type of system restore you can do on your iPhone. It was usually practiced in service center by Apple technicians when dealing with major software issues that caused the device to malfunction. Later on, this method has been introduced among other methods and workarounds to troubleshoot various software issues transpiring on different iPhone variants. Refer to these steps if ever you wish to proceed:

  1. Close any running programs on your computer. Doing so will prevent any of the running programs to interrupt the DFU mode restore process.
  2. Connect your iPhone to your computer using the Apple-supplied USB connector or Lightning cable.
  3. While your phone is connected, press and hold the Side/Power button for about 3 seconds.
  4. Keep pressing on the Side/Power button then press and hold the Volume Down button for about 10 seconds. If the Apple logo appears, it means you’ve held the buttons too long and that you’ll have to start all over again.
  5. If you see no logo, release the Side/Power button but keep holding the Volume Down button for another 5 seconds.
  6. If the screen stays black afterwards, it means that you have successfully entered DFU mode. At this point, you will be prompted with an alert message on your computer saying that iTunes has detected your iPhone. If you see that message, follow the onscreen prompts to complete the DFU mode recovery process.
  7. If you see the Plug into iTunes screen, it means you haven’t entered DFU mode and that you will need to start all over again.

Entering DFU mode requires timing so patience is key. If you don’t feel like carrying out these procedures, then you can always opt for service or repair options.
