Fix iPhone that won't restart
Connect iPhone to computer. If your iPhone only shows the Apple logo on the monochrome screen when forced to restart, you can try using a Windows or Mac computer to fix the problem without fear of losing data. First, connect your iPhone to the computer using the charging cord.
Open Finder (on Mac) or iTunes (on Windows computer). If you have a Mac Catalina or newer, click the two-colored face icon in the Dock to open the Finder. If you're using a Windows computer or an earlier version of macOS, you'll open iTunes from the Start menu or the Applications folder.
Open the iPhone folder. If you use the Finder, click your iPhone's name in the left panel, just below "Locations." If you use iTunes, you'll click the button with the iPhone icon near the top left corner of the app (to the right of the selection list).
Put iPhone in recovery mode. This operation will vary depending on the model:
Devices with Face ID: Press and release the volume up button, then press and release the volume down button. Press and hold the button on the top edge until your iPhone boots into recovery mode.
iPhone 8 or later: Press and release the volume up button, then press and release the volume down button. Press and hold the button on the right side until the iPhone enters recovery mode.
iPhone 7/7 Plus: Press and hold the button on the top edge (or the button on the right side of some models) and the volume down button at the same time. Release when you see your phone show up in recovery mode.
iPhones with a Home button, iPhone 6 and earlier: Press and hold the Home button and the button on the top edge (or right side) at the same time. Release when the recovery screen appears.
Click the Update button on your computer. This is the button in the notification that displays on Finder or iTunes when iPhone enters recovery mode. This option will fix iOS errors without deleting your data.
The iPhone will restart normally if the repair operation is performed successfully.
If the update download process is not completed after more than 15 minutes, your iPhone will automatically exit recovery mode. In this case, repeat step 4 to return to recovery mode and try again.
If your iPhone has been successfully updated but you cannot use the device, you have probably succeeded in restoring factory settings. Repeat this method and choose Restore instead of Update . However, the data on the iPhone will be erased; Therefore, you should only choose this method when you have tried everything.
Contact Apple support if your iPhone still won't restart. Apple recommends that you contact support if you continue to experience any of the following issues: the screen remains black or another solid color, the display appears normal but iPhone does not respond when you touch, or iPhone only displays the Apple logo. To contact support, you'll go to https://getsupport.apple.com, select your device model, and follow the onscreen instructions.
