Help erasing signs of rooted phone

[Hebaz]

I rooted my phone and was going to unroot. I downloaded all the files to my computer but was unable to get into download mode on phone. I followed some guides and instead of getting into that mode it did a factory reset.
I don't see in settings anything about phone being rooted, but it can't be that simple. Can someone help please?

look under Status i believe, it should say rooted or unrooted. also check in download mode to make sure its gone from there...
