How to flash a RUU on a rooted HTC One X (Evita) using TWRP Is it possible to flash a ruu on a rooted HTC One X (Evita).

Actually, I have a AT&amp;T HTC One X (evita) and I want to flash with an international rom of HTC One XL. It will be good if any one know a link of rooted stock rom of HTC One XL international version. 
I am no more using AT&amp;T and dont want any AT&amp;T apps.
RUUs are flashed using the bootloader, not recovery. Reboot into the bootloader and install using fastboot.
