Hi,
for what reason do I a kernel flash? Are the rom included kernels better then a lonestanding once? can I flash any kernal to any rom?
what is the benifit of flashing an other kernel then the once ued in the rom?
thanks
When you change the kernel you choose a better kernel then stock.
They are more tweaked and habeas more support fir different things.
**Using my own JPX kernel, z4mod, 345MB Ram and ext2 filesystem**
- Different file system (better battery life) (I'm still experimenting with finding the right one)
- Access to the kernel allows you to use the led backlights on the buttons for notifications.
Those are currently the main reasons why I flash diff kernels.
You can have direct acces to one of the most advance lag fixes around(voodoo) better performance ,overclocking ,color correction for ur display,more user accessable ram and so on

Good question.
Samsung open-sources their released ROMs from time to time and many of the "kernel-hackers" (I'd call them plain hackers, what's with the prefix?) here utilize it to add/provide features and fix bugs (bugs are overlooked by people, its normal).
For instance, SpeedMods' kernel provides an Overclocking support for your Phone's CPU, if you want that extra juice. Likewise, Voodoo provides a set of visual enhancements among other things.
HTH
Another important reason is to regain 2e recovery if you lost it after flashing a stock firmware. This assumes the kernel you choose includes this feature
Fine, thank you all!
Hello am currently using this rom and would like some help on recomendation for what kernel would be best for this rom Thank You

Rom
I used this
I used Semaphore kernel 2.5.0. (Mostly because it was Voodoo sound compatible, makes a huge difference)
I found the kernel to be very stable. You can install 2.5.0 or 2.5.0bm (more ram but no 720p video recording in the bm version)

Hi !
I use Semaphore 2.7.4 with JW6 and though it's good, it still lags and the screen freezes at times. I am in Thailand but use Australian firmware cause officially there is no 2.3.6 for SGS here.
Tried midnight and speedmod but they are not so good for my phone. Is there a Devil's kernel available for this Rom ?
Somebody please advise me !
Thanks !

There isn't Devil kernel for JW6, only for CyanogenMod 7 and CyanogenMod 9. I think you tried all of available kernels. You can also try CF-ROOT kernel (only root, without mods in kernel).
JW6 is one of the latest and best ROMs for our I9000, so I'm shocked that you are not happy with it. Lags? Freezes? When?
Maybe you have some bloatware that are slowin' down your phone?
If you want stable and fast ROM, flash stable CM7 and use it's stock kernel.
CM9 is also good, but latest nightlies have some random issues (eg. weird ringer, missing power widgets).
Maybe try MNGB by Mialwe. It's my favourite, because it has many features and is responsive and fast. I never had lags with the kernel and it is made for JW4/5/6!

Guys I have made a custom rom based on CM7.nAa 14 kernel is compatible with CM7.But I want my custom rom also to support it.http://forum.xda-developers.com/images/smilies/crying.gifI have downloaded the .ftf kernel file and I have also extracted it.What changes do I have to do in my rom to make my rom work with the kernel?
Please give a detailed answer.
@OP
Well kudos to you for finding the right section. And what CM7 ROM exactly have you based your ROM on?
It already started working.But thanks for you trying to help.
What I want to know is that there is no networking in my rom.
Please help me fix it.I am talking about a custom rom developed by me based on cm 7.1.
What CM7.1 ROM have you based this on? I'm asking whether you have based your work on any existing ROM or not and the name of that ROM. If that ROM supports nAa-14 kernel, then your ROM will support nAa-14 kernel too.
My rom is supporting the nAa 14 kernel,I have tested it I have a bug in the network. It has no network at the moment. Do you know a fix for this bug ? I am running a rom that is developed by me and I am now testing it.
I haven't released the from here yet.

Network bug? I don't even know if logcats can be used to debug. Can you try re-flashing the kernel and the ROM?
Basically you not need to change anything in the kernel. You need change the userspace drivers in the rom to match with the kernel level drivers. Both active x8 gb kernel (nAa and alfs) use similar drivers, except the proximity sensor (nAa use a modded one, alfs use the stock driver), you can use both with the correct libsensorservice and hw libs. And not 100% sure, but nAa use the older kgsl driver (1.1) alfs use newer (1.2), need to change the driver in the rom (libgsl.so).
To solve the network errors, you need to check the RIL related binaries and settings. Better if you give more detailed infos your base rom, the "cm7.1 rom" is not enough. CM7 but the origins? CM7 exists on thousands of phones. Better if you use x8 rom, or rom from a phone what use same hardware (msm7x27 like lg p500, galaxy mini, htc legend, etc...)

What more should I add to"cm 7.1"? Please make it clear. Its downloaded from the cyanogen mod download center. It is used as my base rom. I modded it with certain tweaks and replaced many apps and also added many other mods
Sent from my X8 using xda app-developers app
You could have said that it was downloaded directly from cyanogenmod.com for a start. It's pretty confusing when you say just CM7.1 because there are hundreds of CM7.1 ROMs lying around the Development forum, some for stock kernel, some for nAa-gb and others for alfs-gb.
Let me give you a tip if you're just adding tweaks and other mods, and not modifying it on a large scale. Instead of releasing a ROM, why not release a flashable-zip that will make required changes to the existing ROM that users are on. It will be unique and if you want, I can help you with it.
Summary: Why waste time releasing a ROM (~80MB) when you can release a flashable-zip (~10-15MB)?
Cheers.

I just asked what is your base rom because we not have official cyanogenmod support. If you use only the cm repo to build a complete rom, it will be really hard, due the missing device specific parts. So, the question again (I hope it is clear): you use only the cm repo as base OR use unofficial cm repo from nAa (with working device specific settings/codes) OR use prebuild cm7.1 rom from x8 OR use prebuild cm7.1 rom from other phone. All options is a cm7.1 rom, but all need different works.
From the best to the worst:
1. Use the minicm repo from nAa (nothing to do to get fully working rom)
2. Use prebuilt x8 rom as base (basically not need to do anything)
3. Use the official cm repo (need lot of work because missing a lot of thing)
4. Use any non x8 prebuilt rom (basically the hardest way, need large amount of work with hw related things)

We used to have official CM support till CM7.2 (I guess). It's stated in the CM Shakira page. And you can build CM7 from source as EET has explained in his tutorial. But in any case his best option (if he's going to compile from source) is to use MiniCM7 repo. It's the most updated one.
Plus it will support nAa-14 without any modifications.
The OP wrote this is cm7.1, not 7.2 As I know the official cm7 support is not complete, but my knowledge is NOT unlimited And we not have cm kernel.

I am using a prebuild x8 rom and modding it
And what is the original rom, what you use as base rom? If it is a stock kernel based rom, you need to change the drivers (sensors, gsl, egl, etc) to work with nAa kernels, if it is a minicm based rom, nothing need to do it will work with nAa kernel.

I think he got over that problem by now. LOL.
No man its not working.
See I will explain my question once more. I am using this rom as my base rom: http://download.cyanogenmod.org/?type=stable&device=shakira
I want to make this rom compatible with custom kernels like nAa 14 and alfs etc so what should I do exactly?
If I have to change my drivers then please explain to me how to change my driver to these kernels and also tell me where to find the driver files in the rom and also tell me the download link for the drivers please.
I will be very grateful!
THANKS in advance. Please someone help me.
Hi,
I installed a custom ROM in my P990 and I got a problem which I'm pretty sure that's related to the kernel.
I'm using the new bootloader layout, CWM recovery 6.x.x and the problem is the same with any rom using the Kowalski kernels.
BTW: I am using Kowalski kernel from this post: http://forum.xda-developers.com/showthread.php?t=2097788
With the version M1, the sound recording crashes with any app that uses the sound recording modules (like the google NOW app or the sound recorder included in the ROMs). And with the Apha version the WIFI doesn't turn on at all (i've tried all releases including the last version kk-exp-127-alpha_31-newbl but without success).
I don't have other option but to go back to stock kernel. Anyone has the same problem?
For information: The roms I've tested were:
The ROM - http://forum.xda-developers.com/showthread.php?t=2420304
Avatar Rom - http://forum.xda-developers.com/showthread.php?t=2167192
Both have the same problem. Anyone?
Thank you in advance.
I think, you're using wrong Kernel. Download from Kowelski 3.1 kernel. Try with 32mb ram hack. I really don't think that 2.6 kernel works on these roms. Good luck
