I was searching for a custom ROM for Samsung Galaxy Y Duos GT-S6102 on internet and I found one on XDA Developers forums. The name of the ROM is X Duos V3 ROM. The ROM Thread is present on XDA Developers forum. The installation process is pretty simple. I did not face any issues during the installation. I have made a walkthrough video of this ROM after I finished with the installation. The ROM gives really nice look and feel to the phone.
