are you looking for stock rom or custom rom?
if custom, there are many variety of it with many advantages (minus the warranty void and possibility to brick the phone)
the highest stock android version for i9100G (yes, i know yours is i9100) is 4.1.2...
so if you are looking for 4.2.2, custom rom all the way~
