Update Samsung Galaxy S3 to Jelly Bean with SuperNexus ROM [How to Install]

The international variant of the Samsung Galaxy S3 has received the SuperNexus ROM based on Android 4.1 (Jelly Bean), courtesy of Faryaab, recognised developer and contributor at XDA developers forum. The developer claims that SuperNexus is completely built on the Android Open Source Project (AOSP). It is based on the latest CM Kernel without any visual changes. "This will turn your Samsung Galaxy S III into a Jelly Bean'ed Galaxy Nexus," claims Faryaab on the XDA developers forum.
