How to unroot?

[Tomaster]

I need to return my phone because of a problem with the audio jack, but obviously the fact that it's rooted is a little bit of a problem. Is there any way to bring it back down to unrooted, with no Clockmod recovery either?

if you can get to recovery (power up while holding x), use link one, option 6
