Hi guys,

This is the SpeedMod kernel for Android ICS for the Samsung Galaxy S2 GT-I9100.

This kernel only works with Samsung ICS based ROMs.

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

>>> CLICK HERE for more info and the DOWNLOAD links.

>>> CLICK HERE for the Frequently Asked Questions list.

Current features:

Root and CWM:
- Automatically installs root (su) but can be disabled
- CWM recovery 5.x

Screen and misc tweaks:
- init.d, TUN, CIFS, IPV6 Privacy support
- MMC_CAP_ERASE disabled to fix the hard-brick bug (this kernel is "safe")

Performance:
- CPU governor tweaks: increase responsiveness
- IO tweaks
- Read ahead tweaks
- Compiled with optimizations using Linaro GCC toolchain
- Switched to SLAB instead of SLUB
- Multi-core aware scheduler SCHED_MC

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

Hardcore you know the score :D

K2-21 remains the best ever kernel for the SGSII (obviously before ICS)
So as soon as CheckRom - GC and Leo are finished their work and it is updated i will undoubtely be flashing only 1 kernel and it'll be this one:cool:

Good to see you back!

I was a bit afraid that you made the sensible switch to Galaxy Nexus as well. Looking forward to see your SGS2-ICS kernel :)
