Update Galaxy S3 I9300/SK-3G to Android 4.4.4 Kit-Kat back-to-n00t Un-official Firmware

Samsung tested the Official Android 4.4.4 Kit-Kat for Korean Galaxy S3 and since Android 4.4.4 Kit-Kat runs smoothly on a device with 512mb of RAM, it had no problem running on a device with 2GB of RAM. So, the XDA community thought to bring the Galaxy S3 e210s ROM to the International Galaxy S3 I9300. How ironic, Koreans were porting the Official ROM of I9300 to e210s and XDA developers are doing exactly the inverse. The ROM was then heavily debloated, De-KNOXed, Deodexed, Zipalinged and Compressed and since it is not based on N7100 ROMs, it is far smooth and faster than all the other Kit-Kat ROMs. The ROM is based on TouchWiz Android 4.4.4 Kit-Kat, and it will work on only the International Galaxy S3 I9300 and Galaxy S3 SK-3G.

This ROM is best for those who wants to stuck on Stock ROM and yet wants speed and performance, since this is the only Android 4.4.4 ROM out there for Galaxy S3, yet don’t want the Bloats and KNOX.
