Default Can I do a basic phone reset?

http://forum.xda-developers.com/show...91895&page=286

That is the root the phone has. I bought this phone used, but I want to sell it and rebuy the t-mobile version so I can get wifi calling again.

So I want to know if I can do the standard phone reset in the settings option without having to worry about anything. Can I just do it without having to reroot the phone or do anything? I really don't know much when it comes to rooting, so I want to make sure doing a reset via settings wouldn't deroot the phone or brick it.

Thanks.
