[KERNEL LIST] Galaxy S I9000 Custom KERNEL List [08.05.2011]
This is a list of custom kernels, not ROMs and there are kernels that aren't listed here yet (either new kernels or newer versions), so be patient - I'll try to update ASAP (or when I feel like it )
It is meant for people who want's to find out what kind of different kernels there are in XDA forums and then users are able download/install kernel that he/she wants to try out. This is not about comparison of kernels (but you can vote the best kernel), just a simple list of links to kernels and some basic info about those - so users don't need to search the whole 'Galaxy S I9000 Android Development' thread to find suitable kernel.
Thanks for feedback and updates. You can write a reply or send PM if you see new kernels lying around (that are not listed here) or just if you have any questions or so...
NOTE: Me or kernel developers are not responsible any problems caused by installed kernels. By flashing your SGS (or even installing su?) might void warranty. Before flashing check that your phone can go to download mode.
Some important information about the listed items.
The information about listed kernels are stripped due to size limitation of single message and therefore I couldn't include all posible information about each kernels. Remember to check peroidically this list of kernels from their threads for possible updates (once a day/week/month).
The reason for splitting list to two messages is the limit on one message size.
Remember that some kernels have both Froyo and Gingerbread versions (and some even eiclar), for example [16.04.2011][CF-Root 3.1] JP*,JS*,JQ3,JV1/K/B - su+bb+2e/CWM - rfs+ext4
and that's why it is listed in both lists
Please notify me (pm or whatever) if I have made a mistake and some item should be in other list or both lists.
The Gingerbread kernel List
ps. Sorry about some problems in links, colors etc...
I edited this list with separate text editor - not in browser.
Included in the image are:
- own busybox 1.18.4
- TUN support
- No more RFS at all (if you want)
- JVB source based
- CWM 188.8.131.52
- security fixes
- low latency
- filesystems: jfs, ext2/3/4 (using ext4 driver), reiserfs, rfs (not on Ultra)
- CIFS support
- Voodoo SoundV8
- Preemptive RCU (only on Ultra)
++++++++++++[16.04.2011][CF-Root 3.1] JP*,JS*,JQ3,JV1/K/B - su+bb+2e/CWM - rfs+ext4 ++++++++++++ NOTE! This kernel is listed in both Gingerbread and Foyo lists
This rooted kernel is for the "rooting beginners" and those who want to keep as close to stock as possible. CF-Root takes the kernel from an original Samsung firmware, and just adds root, busybox, unprotected recovery, and CWM compatibility.
If you are looking for highly optimized kernels or kernels that perform specific functions, look elsewhere. All CF-Root's are based on original Samsung kernels, they are NOT recompiled, and thus ensure maximum compatibility.
THIS IS NOT A ROM - it is only a kernel. You need to have a firmware already on your device. You do NOT need to wipe anything for this patch. You DO need to read the instructions.
MAKE SURE YOUR PHONE CAN ENTER DOWNLOAD MODE USING THE KEYCOMBINATION WHILE BOOTING BEFORE FLASHING CF-ROOT (or anything, really)
There have now been over 200.000 downloads of CF-Root and many more if you include ROMs, kernels, ect that use it. Don't be a leech, buy me a beer (and use the "Thanks" button!)
- The kernel is fully stock and taken from the original firmware, with just the following added:
- Superuser 184.108.40.206 FROYO ( CF-Root < 2.4 versions )
---- Busybox 1.15.3 or 1.17.1 (if not mentioned in the filename it is 1.15.3)
---- "2e" recovery (can flash unsigned update.zip's)
---- Integrated fix for ClockworkMod's nandroid (220.127.116.11+) GINGERBREAD ( CF-Root >= 2.4 versions, JVK and newer )
---- Busybox v1.16.2androidminimal (from CWM)
---- Integrated CWM 18.104.22.168 / RFS
These kernels are provided as-is without warranty. I'm not responsible for any problem you can encounter with your phone or if your cat suddenly dies.
Although, don't expect support even if I will eventually help since I love cats.
Note : These kernels are only compatible with CM7 and MIUI roms !
- Up to 1.5GHz CPU OC and 247MHz GPU OC (Thanks morfic)
- Undervolting using Pimp my CPU or Voltage Control
- Voodoo Sound & Voodoo Color (Thanks Supercurio)
- FPS uncap (from 56 to 66) from JPX source Reverted for now.
- Various tweaks for more smoothness and reliability CHANGELOGS IN #2 POST
This is a basic test version of the SpeedMod kernel for Gingerbread.
This kernel is for the International Galaxy S GT-I9000
This kernel has NO LAGFIX support yet. Please UNDO LAGFIXES before flashing this kernel.
There is also no built-in CWM Recovery yet.
For now it has:
- MDNIE Sharpness Fix and some color tuning
- FM Radio sound fixes based on Voodoo Sound
- Conservative CPU governor for better battery life
- Volume level fixes
- Startup script tweaks
- Disabled Android Debug Logger / logcat
- Updated to jhash3
- Improvements to sound quality: 128x oversampling, disable DRC and de-emphasis
- Compiled with O3 optimizations using latest codesourcery 2010.09 toolchain
I'll implement the SpeedMod Froyo features bit by bit as I have the time to.
TEST VERSION: K15D-T4:
- With 334MB RAM
- Fixes front camera problem
- Disabled kernel debug logs / printk
Join us on freenode: #suckerpunch
Huge special thanks to Xcaliburinhand and eXistZ (current co-dev), without them, this kernel wouldn't eXistZ.
Talon Kernel build 0.1.4:

This is a dev-in-progress Ext4 Kernel based on Voodoo code for Samsung's Gingerbread.
Fixed since last release:
- conversion voices. Bye chipmunk, hello Linda!
- disk-free checks
- Well integrated CWM 3.x
- Performance / Smoothness optimizations if any.
Show some support in donation to help a true stable port!
rooting is as easy as installing Superuser from market.
You can control the Ext4 lagfix status with Voodoo control
Kernels are not yet supported, bug reports are now welcome
Dev & hack discussion is always welcome!
Another Sticky material. I hope you keep updating this list for it to remain stickied.
I have rated this thread with 5 stars.
PS : You could actually make sections for 2.1, 2.2, 2.2.1. For example, there are some old 2.1 kernels lying out there that can be helpful to some users. Maybe you can include lagfixes like OCLF with warnings on when & when NOT to use it.
if you like what I say, there is always a THANKS button below.
One suggestion, why don't you put up a voting section so the users can select which kernel they like most. This would be great help for newbies. I personally love speedmod kernel, have been using it ever since I got my SGS in Dec.
