None of my friends here have an Apple. It wouldn’t take my password, so I changed it…won’t take that either. And we no longer have an Apple store here :(

iTunes on a Windows PC works.

Download and use iTunes for Windows - Apple Support

If you can't update or restore your iPhone or iPod touch - Apple Support

Restore your iPhone, iPad, or iPod touch in iTunes on PC - Apple Support

Ask a friend if you can use their computer or take it to an Apple store and use one of theirs.
