Hi guys,

This is the SpeedMod kernel for the Samsung Galaxy S3 GT-I9300.
This kernel is for Samsung Android Jelly Bean ROMs only.

SpeedMod's core features are:
- Super stable: No undervolting, overclocking or potentially unstable modifications
- Fast and smooth: Compiler and code optimizations
- Excellent battery life: Remove unecessary logging and debugging

Download links: >>> CLICK HERE for more info and the DOWNLOAD links.
>>> CLICK HERE for the Frequently Asked Questions list.

>>> CLICK HERE for the CHANGELOG.
>>> CLICK HERE for the DOWNLOAD links.


Current features:

Root:
- Automatically installs root (SuperUser and su) but can be disabled

Screen and misc tweaks:
- Auto-brightness increased slightly (in low-to-mid light)
- MDNIE screen sharpness and color tuning (improves text readability)
- init.d, TUN, CIFS, IPV6 Privacy support
- Fixed freeze on FC problem with Samsung ICS & JB ROMs

Performance:
- CPU governor tweaks: increase responsiveness
- IO tweaks
- Read ahead tweaks
- Compiled with optimizations using CodeSourcery GCC toolchain
- Optimized GPU DVFS
- ARM CPU topology support
- SCHED_MC multi-core aware scheduler

Turned off unnecessary logging for better smoothness and efficiency:
- Disabled Android Debug Logger / logcat
- Disabled Samsung debug
- Disabled various kernel debugging, statistics and tracing options


Instructions on how to enable logcat and disable auto-root are in the 3rd post (below).

Here is how to change some of the kernel configurations:

[HOW TO ENABLE LOGCAT]

If you are a developer or want to re-enable logcat for whatever reason, do this:

adb shell
su
mount -o remount,rw /system
echo ANDROIDLOGGER >> /system/etc/tweaks.conf
mount -o remount,ro /system

[HOW TO DISABLE AUTO-ROOT]

Create a file called ".noautoroot" in either /system or /data. This will disable the auto root installation. This example, shows how to remove root completely:

adb root
adb shell
mount -o remount,rw /system
rm /system/xbin/su
rm /system/app/Superuser.apk
rm /data/app/Superuser.apk
touch /system/.noautoroot
mount -o remount,ro /system
sync
reboot

[HOW TO RE-ENABLE AUTO-ROOT]

adb root
adb shell
mount -o remount,rw /system
rm /system/.noautoroot
mount -o remount,ro /system
sync
reboot
