How to unroot my htc one s?

[comono]

I bought my htc one s used (I buy and sell phones) and it came rooted
I cant get the updates from htc though so I'm not getting patches for wifi or any bug fixes
I would really appreciate a guide to unrooting because i have no use for it and am normally good with tech stuff like this but can't figure it out :/

Thanks!

Boot in to recovery and wipe it.

You need to lock the bootloader (if not already lock, boot into the bootloader by holding volume down and power button)
You should see at the top "locked" "unlock" or "relock" (probably not locked since it's been rooted)
Once the bootloader has been relocked, flash t-mobile's ruu.
Now you can go into Settings and update the software.
