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


Deodexed, zipaligned, uncompressed

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

/* Changelog */


    SMS, MMS issues fixed



    Korean characters from the dialer removed

    AllShare and Screen Mirroring fixed

    Mobile Data, 2G/3G toggle and SMS Delivery report fixed



    CSC reworked from I9300XXUGMK6_BTU

    Google Apps updated to improve stability

    Camera Shutter Sound control enabled

    APN and SPN fixed

    Kernel updated to E210SKSUKNK3

    Entropy hook on storage removed for performance

    Random drivers updated to the latest mainline Linux

        - Every forkers of this project is recommended to also rebase their ROM

    Debloated even more

    Compiler optimizations for kernel fixed and improved

    L1/L2 caches size defined (by JustArchi)

    Now uses new ARM instructions set

    Full unaligned access enabled

    Linaro's power-efficient workqueues merged

    Random drivers backported from Linux 3.19 for performance

    Westwood as the default TCP congestion control



    Faulty Camera fix removed for fixing Cameras that has worked on V1 and V2

        - If Camera worked for V1 or V2, flash V5. If it still doesn't work, do a full factory reset

        - If Camera never worked for V1 or V2 and now, V5, flash the Camera fix from here : https://forum.xda-developers.com/galaxy-s3/development/fix-camera-stopped-error-samsung-based-t2499158

    Patches model name to SHW-M440S for SHW-M440S users

    USSD fixed (Maybe. I haven't tested out yet)

    Graphics glitches fixed

    Wireless mirroring fixed (Maybe. I haven't tested out yet)

    Unaligned access enabled

    Deadline I/O scheduler with latency improved

    500MB of vnswap enabled (should improve memory managements and random reboots)

    Uses newly improved LZO for ramdisk & zImage and swap

    AIO(Asynchronous I/O) enabled and improved 30%

    Take advantages with Android 4.4.4 with extra free kbytes tunable

    MMC and ext4 performance improved
