Default [Q] Help returning to stock. Radio 3.1204.171.33

As the title says I'm in need of help returning to stock. I have an unlocked european international One X + with radio version 3.1204.171.33. As such there is no RUU I can find that I can flash to return to stock. Rather stupidly I have deleted the nandroid backup I had of the original stock system. So I'm wondering if there is any other way I can get back to stock? Any thoughts or contributions greatly appreciated. If you need any other info please just ask.
