Hello JVLIAN,
Welcome to Apple Support Communities!
We want to help resolve the error you're seeing when resetting the phone.
Start with the steps here to help isolate the software issue and resolve the error:
"Try these steps first
- On a Mac with macOS Catalina 10.15 or later, make sure your Mac is up to date. If you have a Mac with macOS Mojave 10.14 or earlier, or a PC, make sure you have the latest version of iTunes.
- If your device couldn't be restored and you get a message that "an unknown error occurred [error number]," use these steps."
This Apple Support page has the full details and more steps to take to further resolve the error message: iOS update and restore errors - Apple Support
Cheers!
