This is a modified version of the VillainTheme System specifically set up for the I9305. The Partitions are set to the correct locations for starters, but that's just the beginning...  What this version is capable of doing is injecting files into the vrtheme data before it starts installation, depending on what Firmware is installed on the Phone.  So, for example, this is what you can do:  Let's say you have edited SecMms.apk and you've also edited the androidmanifest.xml in this file, however you want this to support multiple Firmwares. This is how you would set up the installer.  - Copy all your files to the /vrtheme/system/app/SecMms.apk folder except for the androidmanifest.xml and META-INF folder - Copy the META-INF folder and androidmanifest.xml to /tmp/vrtheme/<Your desired FW>/system/app/SecMms.apk - Repeat the last step for any other Firmwares you wish to support
