  • Press and quickly release the Volume Up button.
  • Then press and quickly release the Volume Down button.
  • Finally, press and hold the Side button for a few seconds until you see the Apple logo.


For starters, the Side button here refers to the Power or Sleep/Wake button in previous iPhones.

You can force restart your device even if the screen is black.

Second method: Connect your iPhone 8 Plus to a computer and use iTunes to access the system.

If your iPhone still doesn’t turn on or start up after performing a force restart, then your next option is to use iTunes and attempt to access the iPhone system. If iTunes is able to detect and communicate with your iPhone 8 Plus, then you can go ahead and create a backup of your iPhone data then try a system restore. To help you get started, refer to these steps:


  • Secure a computer with iTunes program installed. You can use either a Windows PC or Mac computer preferably those running on the latest platform or operating system.

  • Press and quickly release the Volume Up button. Then press and quickly release the Volume Down button. Finally, press and hold the Side button until you see the Recovery Mode screen. Do not release the button yet when the Apple logo appears as you need to enter Recovery Mode to proceed. So you have to wait for the Recovery Mode screen to show up and then that is the time you will release the buttons.


Note: If you have successfully entered Recovery Mode, try to backup your data as this might be your last chance to do so if a serious hardware problem is present.


  • When you’re prompted with the option to Restore or Update, select Update to command iTunes try to reinstall iOS without erasing your data. Otherwise, select Restore to try to restore from a previous iOS backup.
  • Wait until iTunes is able to finished the entire process then see if your iPhone is now back up and running.


Using iTunes will help you determine whether or not the problem is on the iPhone display. If iTunes is able to recognize your device, then what you’re dealing with is a display issue in which the iPhone is stuck on black screen. In this case, you have to deal with that problem first. Black screen issue on iPhones are usually caused by a software glitch or worst, physical or liquid damage on the screen components.

Once you get your iPhone to charge, proceed with troubleshooting on power issue. After the elapsed time of charging, try to turn it on by pressing the Power or Side button.

Step 2. Check for hardware damage.

A hard fall or liquid exposure can lead to potential hardware to any of the iPhone components If the iPhone stopped working and went dead after it got wet or dropped, then this can be the culprit. Symptoms of liquid damage may transpire sooner or later. A visual inspection of the outside of the iPhone can help verify if this is the case on your end.
