Default [KERNEL] Galaxy S2 Kernel Collection

Hi:


I open this thread in order to provide in one post all our SGSII current kernel, where you can download each of them. To discuss and talk about them used the wires and opened thread please. I will update as it exits new versions.

THANKS FOR ALL COOKS

Although he put in each kernel, how to load a kernel based on their extension usually is:
- TAR: It flashes by Odin or with the option Flash Kernel from CWM app.
- ZIP: It flashes from the Recovery menu.

If you see a broken link, want to add or delete some kernel or whatever, send me a PM or leave a message here. Thank you.

It is very difficult to recommend a specific kernel it does not behave the same way in each SGSII. It is best to try and stay with the one you like and suits your needs.

Author's notes:
+ Root
Kernel comes "instant rooted", after flashing this kernel your system is completely rooted (su, busybox and the Superuser app).
Nothing more needs to be done, totally newb friendly
+ ClockworkMod Recovery 4.0.1.4
This kernel also comes with the ClockworkMod recovery instead of the original stock one.
+ ADB with root priv's in recovery mode
When booted into recovery mode you have ADB available to connect to from your PC.
ADB also runns with full root priv's in recovery mode for all your haxx'n'tinker needs (in normally booted OS mode ADB still runns "secure" with only user priv's, use su to get root there)
+ Custom boot scripts
There is some bootscripts you can put your own commands in for being executed during boot.
The scripts are /system/bootrc.sh and /data/bootrc.sh.
+ Additional modules natively supported and loaded on boot
The original plan was to integrate these into the kernel, but due to hitting size limits of the zImage I decided to have them loaded from external directories.
Currently supported modules: (these modules are compiled together with the kernel and are included in the download!)
- slow-work.ko (not needed on Android 2.3.4 FWs, like XXKG2, e.t.c.)
- cifs.ko
If these modules are present in either /system/lib/modules or /data/lib/modules they will be automatically loaded at boot and are available to use (for example in case of CIFS, just get CifsManager from the marketplace and start mounting your shares)
+ Custom Bootanimation and Bootsound
This kernel also supports using a custom bootanim (bootanimation.zip) and bootsound (PowerOn.wav).
To install, simply create a folder "import" on in your /sdcard and drop your files into it, i.e.:
/sdcard/import/bootanimation.zip -> for bootanimation
/sdcard/import/PowerOn.way -> for bootsound
If either one of those is present upon the next boot they will automatically be installed to the correct path and be available.
+ Custom Boot-LOGO !
This let's you change the logo shown BEFORE the bootanimation (usually the "Samsung Galaxy SII" splash screen).
Similar to the bootanim and -sound, copy the desired logo.jpg (480x800, max. 100k) to:
/sdcard/import/logo.jpg
Upon the next boot the new bootlogo will be installed!
Please read the additional note about installing a new bootlogo bellow!
+ BLN support
This kernel has BLN (=BackLight Notification) support!
Just install the BLN Pro App from the market (to actually use/get the notification lights you need the paid version, the free version only lets you test if BLN works propperly) and off your blinkieness goes
+ Touchscreen Sensitivity Fix
vitalij's touchscreen fix to make the touch more responsive again when performing movements on the screen.

- Date: 15/07/11
- SetCPU: Yes
- OC: 1.400
- UV: Between 800 and 1400mV
- BLN: Yes
- Bootanimation: Yes

Author's notes:
My new kernel!
Will come in two flavours:
- U1 - based on Samsung Update1
- U2 - based on Samsung Update2 - not released yet.
Features:
- support for SetCPU OC (upto 1400MHz)
- UV between 800mV and 1400mV
- support for Boot Animation
- support for BLN
The goal of my first kernel was to take the battery savings gained from HardCORE's kernel and allow undervolting and underclocking to further improve battery life. I added Boot Animation and BLN support just because I could. This kernel adds to my previous kernels, taking bits and pieces from here and there also.
Thanks also to the authors of Ninphetamine kernel - their SetCPU supporting code was the basis for the SetCPU support in this kernel, I have also used BLN code from their Git Repository, thanks to creams.

Author's notes
Netchip´s kernel was terribly, there where thousand and one bugs.
Such max overclock to 1400 MHz, no GPU overclocking, bad scripts.
Scripts who works not, it was one big drama.
But it was also great, light, quick, not one fancy kernel.

And here I come to introduce my new kernel .
It is not a big drama, it is super, fixed some bugs by Samsung, CPU overclocking to 1.6 GHz, GPU overclocking, BFQ v2-r1, BLN, bootlogo, bootanimation and much more in the future .

I am inspired by Hacre, Chainfire and HellcatDroid.
Hellcat is very kind, and helps me with ex. the compile issue.
Also Hacre was nice together me, ex. the CPU overclocking code.

But now further on the kernel, the features

-Bootanimation support, place it in /system/media/bootanimation.zip
-Bootlogo, place it in /sdcard/getin, and give it the name, logo.png
-CPU overclocking till 1.6GHz
-GPU overclocking
-BFQ v2-r1
-Removed other schedulers
-Instant root
-Busybox
-Clockworkmod 5
-KI3 initramfs
-I use the "hidden" p12 partition as tmp, so if bootlogo dont work, lemme fix it
-Compiled with AOSP 4.4.0 toolchain
-BLN
-Init.d support - /system/etc/init.d/
-EFS backup script
-Touchscreenfix set to 5 - thanks to vitalij

It is newb friendly, you can flash it via Odin, and all is installed
Thus flash it via Odin!

Disabled Profiling support and debugs, added ThumbEE, Improved Control Group Support.
Added some CFQ IO tweaks
Changed dalvikvm heapsize to 60m (this should improve performance on tasking)

Sorry, did not mean to break your wishes. The links have been deleted. Sorry again.

About the selected section, I thought that since it was an original Development links, this was your site. If not, I can safely delete. No job is my, only collection of links so that users could see and compare the various kernel created by different cooks.

1.6ghz is the highest I've run it and really only for benchmarking purposes. 1.4ghz is stable for me.
