Default [Q] How to reset Samsung Galaxy Ace II x to stock ROM

I recently rooted my phone (Samsung Galaxy Ace II x (GT-S7560M) ROGERS) to CyanogenMod 11 (this version >http://forum.xda-developers.com/showthread.php?t=2564516<) Kit Kat 4.4.1. I would like to unroot and reset to stock ROM. I did not ever create a nadroid or any other type of backup file. I think i understand how to restore the stock ROM, (load it through Odin, the same as CM11) but i can't find a download link that seems legit. I also need to unroot. Any help would be greatly appreciated.
