can i use my ipad pro to restore an iphone

I'm afraid not.

The solution to restore an iPhone or any iOS device is that you must have a computer (Windows PC or Mac) capable of running the latest version of iTunes.

No. You need a computer running iTunes.

You can borrow a friend's or make an appointment at an apple store for more help.
