Installed Resurrection, Lolipop5.1, cid::38, india, How can i recover to stockrom ?

Hi,

I was using 4.2.2 on htc one x india (CID:HTC_38, HBOOT:1.73). Later i rooted my phone and installed Custom ROM ResurrectionRemix, Lolipop 5.1. Now I want to switch back to stock rom (4.2.2.). How can i do that ?

Below are the information :

Current OS : ResurrectionRemix Customer ROM , Lolipop 5.1 (installed)

I was trying to getvar using fastboot to flash ruu and I found below information while executing command "sudo fastboot getvar all"

I want to install stock rom but i am not getting how. I have downloaded above mentioned version from here "http://forum.xda-developers.com/showthread.php?t=2466294" but it mentioned there at it requires 4.1.1. to install.

Can anyone help me on this if it's really needed to have 4.1.1. if i have above getvar all configuration ?

Thanks in advance !!!
