Touchwiz Android 4.4.4 for Galaxy S3

back-to-n00t; Bring the LTE fun back to 3G

/* Introduction */

Previously, Korean developers were porting i9300 ROMs to e210s.

How ironic, we are now porting e210s ROM back to i9300!

 

The Korean letter "눝", pronounced "noot", symbolizes LTE(as you can see).

/* Overview */

Touchwiz Android 4.4.4 for Exynos Galaxy S3 3G

Ported from Exynos Galaxy S3 LTE

Havily debloated

De-KNOXed

Deodexed, zipaligned, uncompressed

Since this no longer bases on N7100 ROM, this is much more stable than other KitKat ports
