First solution: Force restart.

A phone will usually end up being stuck from data corruption. And when this happens, you could be dealing with a major or minor symptom. In most cases, a phone gets stuck on blank or black screen due to minor data corruption from errant apps, faulty updates, or memory problems. And the emerging symptoms are usually minor and rectifiable by a soft reset. But since your phone’s screen not responsive, performing the usual reboot won’t be applicable.

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

Second solution: Plug into charger then force restart.

If your iPhone remains stuck on black screen after performing a force restart, plug it into the charger then let it charge for at least 30 minutes. If your iPhone is able to charge, do a force restart while it’s connected to the charger to end all errant apps from running. It also clears cache from the internal memory and refresh the operating system. All these allow the device to have a clean fresh reboot.

That said, charge your iPhone as you usually do then wait until you see it instigate charging. While it’s charging, carry out a force restart. Refer to the previous steps to get this done.

Third solution: Reset all settings.

Invalid or incorrect system settings configuration on the phone may likewise trigger the same symptoms to occur. This usually happens after installing a firmware update that’s programmed to automatically override the device settings. The alterations may yield to a system error and the transpiring symptom is having your iPhone stuck on blank or black screen. To clear this out, try to reset all settings on your iPhone 8 with these steps:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select Reset All Settings from the given options. This will erase the system settings and restore the original values or defaults without affecting internal data.
  5. If prompted, enter your device passcode to continue.
  6. Then tap Reset All Settings again to confirm.

Your iPhone should reboot automatically when the reset is complete. After the reset, configure individual options and enable core features including Wi-Fi networks to use them again on your device.

Fourth solution: Erase and restore factory defaults.

One of the last possible solutions to consider if the previous methods failed to rectify the issue is a master reset or factory reset on your iPhone 8. This will erase everything and then restore the factory defaults. A factory reset can be carried out through the iPhone settings but since your device is stuck or unresponsive, you will need to use iTunes instead.

Once you’ve got everything set, back up all your important files and then follow these steps to wipe and restore your iPhone 8 to its factory defaults through iTunes:

  1. Open iTunes on your computer. Be sure to use the latest version of iTunes software.
  2. Connect your iPhone to your computer using the original Lightning cable or USB cable. Be sure to remove other USB devices from your computer to prevent any of them from interrupting the syncing process between your iPhone and the computer system.
  3. If prompted to enter your device passcode or to Trust This Computer, tap OK to confirm and then follow the onscreen instructions.
  4. When your iPhone 8 appears in iTunes, select it.
  5. Navigate to the Summary section and then click the button to Restore iPhone.
  6. Tap Restore to confirm.

Follow the rest of the onscreen prompts to complete iPhone reset through iTunes.

Fifth solution: Restore iOS in iTunes.

For stuck problems that could not be remedied by a factory reset, fatal system errors are likely the trigger. If that is so, then a more advanced solution would be necessary. As your next option, you can perform a recovery mode restore through iTunes. This will put your device in a recovery state then clears and fix major system errors through iTunes. Here’s how it’s done:

  1. Connect your iPhone 8 to your Mac or Windows computer using the original Lightning cable.
  2. When your iPhone is connected, quickly press and release the Volume Up button, then press and release the Volume Down button and finally, press and hold the Side/Power button until the phone reboots. Continue holding the Side/Power button even when you see the Apple logo.
  3. Release the Side/Power button once you see the Connect to iTunes screen.
  4. Go to iTunes and you should see a message saying that “There is a problem with the iPhone that requires it to be updated or restored.”
  5. Select the option to Restore, then follow the onscreen instructions to complete the entire iOS restore process in recovery mode.

Allow your iPhone to finish restoring iOS and then see if that fixed the problem.

You can move on and continue to troubleshoot your device if the recovery mode restore failed to solve the problem. At this point, you can try the deepest type of iOS restore or DFU mode restore. This puts your iPhone in a state that’s able to communicate with iTunes on a computer even without activating the bootloader or operating system.
