Default Stock RUU HTC ONE X Download link:(

Hi guys, I'm a fellow noob needing some help. I have a AT&T Branded One X running ICS 4.0.4 "I'm having the system is waiting problem" and the sound has stopped working as well.

I'm wanting to flash stock RUU on the HTC One X but I'm not sure how to find out which RUU I need, so far i know i need Evita but not sure which one exactly..

Thanks
