Unroot?

[seunghyun]

Hi. I'm new here and I was wondering if I could get any help...
I tried looking at some other places and I found this ...

HowTo: Flash Any Ruu - xda-developers

It gives the stuff you need but it doesn't teach you how to do it...
I have no idea what to do.
If anyone could explain what you do in the link above, that would be awesome.

-Thanks

I think flashing the 2.1 Flashback ROM is the best way to unroot:
