HELP! HTC ONE S restore stock rom

[jjtarantino]

I have T-Mobile USA HTC one S. Its rooted with cyanogen on it. It works great but the WiFi calling feature isn't supported by cm. I need a walkthrough via video or text on how to restore the factory ROM or ruu file along with what ruu file I need. Please help Lol I'd appreciate it and no I don't have backup of original ROM as this was my first mod on a cell.
