The very first thing is that its a 4.2 ROM based on Samsung UI.The API level in build.prop is showing 17 which is 4.2.
So I will request you to wait. There is no 4.3 yet for any MTK device.
Second thing, As like earlier its not booting. It stucks on boot animation and in log asking for some libnetcmdiface.so which is next to impossible thing to make a lib for the ROM.
Now I will request you all to please wait and let any MTK device get 4.4 first and then we all will start our work that we can for porting it to our device and other MT6577 device.
