Reset instructions enter diagnostic mode

Hello GoodDistractions,

Welcome to Apple Support Communities. 

Please try the steps as listed here to enter recovery mode and restore your iPhone: If you can't update or restore your iPhone or iPod touch - Apple Support

Put your device in recovery mode and set it up again

1. Make sure that your Mac is up to date. If you're using iTunes, make sure you have the latest version of iTunes. 
2. On a Mac with macOS Catalina or later, open Finder. On a Mac with macOS Mojave or earlier, or on a PC, open iTunes. If iTunes is already open, close it, then open it again. Find out which macOS your Mac is using.
3. Keep your device connected and wait until the recovery mode screen appears:
4. iPhone 7, iPhone 7 Plus, and iPod touch (7th generation): Press and hold the top (or side) and volume down buttons at the same time. Keep holding them until you see the recovery mode screen.
5. Locate your device on your computer. When you see the option to Restore or Update, choose Update. Your computer will try to reinstall the software without erasing your data. Wait while your computer downloads the software for your device. If the download takes more than 15 minutes and your device exits the recovery mode screen, let the download finish, then repeat step 3.
6. After the Update or Restore completes, set up your device.

Let us know if you have further questions.

Take care.
