Hi All,
My first post here. Yay!!
I have SGS2 and wanted to have latest and greatest. Spend few days reading this forum and got reasonable understanding of root, kernel, rom and firmware. I've even update my phone from XWKDD to XXKI3 non-wipe Frankenstein version and updated kernel to stock XXKI3 as well. I also then updated rom to VillianROM 3.0 which is very new and has 2.3.5 in it.
All working great and haven't bricked the phone.
However, I am bit confused and was hoping you guys could clear up my confussion.
Basically what I want to know is, does ROM include Kernel?
If so, did I updated my kernel when I flashed VillainROM?
If someone could explain what has happened when I did below.
1. Flashed XWKDD insecure kernel and rooted the phone using superoneclick.
2. Few days later, flashed XXKI3 non-wipe firmware (pda, modem & csc all in one).
3. Flashed XWKDD insecure kernel and rooted phone using superoneclick.
4. Flashed kernel to stock XXKI3 to remove yellow triangle, phone is still rooted.
5. Flashed VillainROM 3.0
Hope I've asked questions correctly, if not forgive me, its only my first post here.
Every rom uses different kernels, now your phone is using the kernel that comes with Villain rom. If you are not happy with the kernel that you are using now you can download one from forums then change it by flashing it using cwm.

So, in my phone I no longer have KI3 stock kernel but instead "inphetamine2.0.5" kernel which is used in Villainrom 3.
will lookup bit more on this kernel to understand what it has to offer.
thanks for information.

Villain 3 is your rom and Ninpethamine 2.0.5 is your rom. I would suggest that you change your kernel to newer version to Ninphetamine 2.1.3 . Go to kernel forums in xda and read some more and you can get more info about all other kernels and you will find performances of each kernels.

I updated kernel as per your suggestion to Ninphetamine 2.1.3, all appears to be ok and didn't find any difference. Well, I am not that techie and my requirements are mostly basic so won't notice much difference but I am sure it is better then previous version.
Thanks for your help.
Theh were using 2.0.5 with VR rom and according to them its more stable and battery friendly. You can monitor it and if you find it better or 2.0.5 better you can always flash it back.

Basically the ROM developper chooses the kernel that he finds more suitable to his ROM and loadsit with the ROM. You can change the kernel if you want after flashing the ROM. For me, I like the cf root KI3 v4.2 kernel (stock kernel), but if you want to overclock or undervolt you'll need a custom kernel (don't know if nimphetamine can UC/UV, I think it can, if not there are other great options too).
The thing I found with the cf root kernel is that for users that don't know how to undervolt or do most advanced stuff (me included) it has better battery life. Or at least for me the cf root kernel showed the best battery life. At the end, the best is to try various kernels and see which is best for you.

Afternoon all,
First of all I would like to point out I am a complete Android noob I make no secrets about it, have been a iPhone user for a few years with Blackberrys prior to that, so everything is new to me.
I decided to opt for the SGS2 for my newest phone upgrade and after a week or so of use the battery was terrible (holding only 6-7h max). I read through endless threads on rooting/custom ROMs and the likes and decided to try VillianROM 1.4, to help improve the battery.
Managed to sucsessfully install it with no major dramas.
However, I think I may have the wrong CFroot kernal installed. After installing the villianrom, one of the last parts is to update the root kernal, it stated to use XWKF2. mine currently states:
Baseband version - I9100XXKF2
Kernal Version - 2.6.35.7-I9100XWKE7-CL215725
Is this correct?? If not can someone point me in the direction where to download the correct kernal.
The phone is working fine at the moment and the battery is vastly better compared to how it was. I have noticed a problem with the music player, it seems to crash mid way through songs and re-boot, has anyone else had this issue? or could it be as a result of the incorrect kernal?
Thanks in advance,
Shakey
p.s - loving my Android experience so far and dont think ill be going back to Apple any time soon
I would leave well enough alone if its working .
However the VR rom instructions say .
If you are installing from another ROM, or stock ROM, you need to be using the CF-Root kernel, as applicable for your current ROM. You can find CF-Root and
instructions at http://forum.xda-developers.com/show....php?t=1103399
When using this ROM, I suggest the XWKF2 CF-Root kernel, from post 4 of Chainfire's thread.

Thanks for the quick reply jje.
It does seem to be working fine, apart from the music player issue, ill put XWKF2 on and see if that fixes the issue.

I'm looking to load ninphetamine 2.0.5 on my phone and I can't really find a definitive answer to this. Do I need to flash with cf-root first? or can i flash ninphetamine directly over stock without rooting first?
Also I may be a bit confused... no where on the ninphetamine post (that I can find) does it reference versions (mine is ugkg2) or is this not related to the kernel?
Please forgive me for the complete stupidity of the question. I think I've gone into information overload and can't get which parts go with what...
Oh also, if I have to do cf-root do I have to do the kg2? or can I jump straight to kg6?
Read chainfire's instructions about flashing his unsecured kernels. You should go with the KG2.
If im not mistaken, they also come with a custom CWM which you can use to flash whatever rom you want.
Be warned, there is no stock Bell firmware released yet. As such you wont be able to return to youl old Bell once you start flashing.

You can flash the kernel using odin, you don't need to root first as the kernel will apply root for you. There is currently no cf-root kernel for the UGKG2 and all of the KG2 kernels found in the thread are based on entirely different firmwares so it doesn't really make a difference. If you choose to flash a cf-root kernel you can pick any one you want as long as it is 2.3.3 based, since that is the version you currently have.
Ok, and is there any harm in upgrading to a 2.3.4 kernel? Such as the UGKG6? Also what version is Ninphetamine based on?
Hi everyone,
I am new to the Android community and I just have a questions. My main goals from flashing a new kernel and custom rom would be to get rid of bloatware, get better battery life and more customization.
I am planning on installing the Speedmod kernel along with lite'ning rom 6.0. Is that a good choice?
Also, does the order in how I install them matter? Because in the lite'ning rom post,
http://forum.xda-developers.com/showthread.php?t=1095274
it mentioned that it uses the kernel kernel ninphetamine 2.0.5. Does installing the lite'ning rom overwrite the speedmod kernel? If it does, what's the best order of installing the combination. Also, both of these mention that it comes with root and CWM, does that mean I don't have to root it first? And I can just install it straight from stock?
My current plan to install is to:
Install lite'ning rom 6.0.
Then install the Speedmod kernel.
Thank you so much for any input and help that you guys can provide me.
You can flash any kernel over any ROM. You just have to think what you need, choose the kernel on the basis of that.
Regards.
Is there a post where I can find a list of kernels? Or do you have any recommendations?
I am looking for one that is stable, and have great battery life. If it's fast too, thats a bonus
Thank you
Well I only used two so far, Ninphetamine and Chainfire. Outta them CF is the obvious best IMO, Ninpho drained too much battery, may be for BLN, but I won't give a single percentage for that damn thing.

Thanks for the reply. I have a question about BLN. What is it? Every post seems to talk about it but I can't find a definition of it anywhere. :S
And okay, thanks button pressed!

Question on installing speedmod in litening ROM 6.1
hi guys, im trying to install speedmod kernel into my current rom Litening 6.1. But problem comes in when i flashed it via Odin 1.85 after start up the Galaxy SII screen boot screen with Triangle appears without stopping,
Here is my current settings :
Android Version : 2.3.4
Baseband Version : I777UCKH7
Kernel Version : [email protected] #22
BUILD NUMBER : LIT'NING ROM V6.1
Also, I am currently using CF-ROOT 4.0
PLEASE HELP!!! THANKS!!!
Hi all,
I have a few questions now I am running cm7. And I can't find the answers propably because (you're a NOOOB!!!) I lack some basic understanding of the relation between kernels, mods, modems etc.
First the situation: SGS2 (duh) rooted using CF-Root OXA KG3. Flashed CM7 nightly (88 or 89 don't know from the top of my head).
My understanding of the parts is limited to the rom (cm7) is running on top of the kernel. Where the modem fits in I don't know.
Now the questions:
1. Does cm7 have (and am I running) it's own kernel or am I still on CF-Root?
2. If I want to switch to another kernel how would I do it and where can I find kernels working well with cm7? (I know about Swi7chblades thread)
3. Where is the modem for and can I change and improve it? (sorry couldn't find it in the guides nor the glossary on the wiki)
And I thought I had more but will say what pops up when I read your answers.
I think CM7 has a own kernel but i'm not sure
SiyahKernel v2.0 will work for you if you are still running CM7

Yeah I am still running CM7 and plan to stay there until their is either an ICS version or another ICS rom. Thanks for the kernel suggestion will check it out.
edit: SiyahKernel v2.0 looks promising, I'll put it on the list of things to try.
I tried siyah 2.0 stable but it wasn't a success. I ended up going back to stock and flashing cm7 again. On the modem front I flashed to KI4 and things seem a little better. But I still don't really know what to look for. Anyone?
CM7 has the kernel from cyanogen dev codeworkz. I'm using siyah ATM though which is decently stable.

Ok I am really confused about this. So I just rooted my new Galaxy S II I got (the CF method using ODIN) and I was considering installing Cyanogenmod. However I changed my mind when I decided I could put a kernel on the stock instead. Now when I read thread for the kernel (as well as going to the website) it says it includes CWM touch Recovery with gesture support. Now does this mean when I flash the kernel with the recovery I got from rooting, it will also flash over the current recovery to the touch one? If I get OTA updates and apply them, will it remove the kernel and my root access? Also I am wondering has anyone had problems with this kernel?
Thanks for all the help.
Ainslie.
1) If you flash Siyah, it will overwrite/replace the current version of recovery you have, yes.
2) If you flash any stock firmware (including OTA updates), yes, of course you'll lose root. Any update will have a new stock kernel which will replace your existing kernel. If you do an update, you'll need to re-root your phone.
3) I've been using Siyah since about the 2nd week I got my phone (>8 mths) both Gingerbread & ICS and I've never had any major problems with it.
In saying that, obviously your experience with a given rom or kernel will not be exactly the same as someone else, because everyone has their phone setup differently/uses it differently.
So do a Nandroid backup in CWRecovery before you try Siyah, and if you don't like it, restore your backup. If you're going to use Siyah, I very much recommend you read the dev & discussion threads (certainly since Gokhan has been doing ICS builds at least). Any questions once you've installed it/started using it, ask them in the discussion thread (not the dev thread).
Ah cool thanks.
Also just one more questions.
When the new recovery is flashed with the ROM will the CF-ROOT custom CWM app work with it? Or will I have to download ClockworkMod from the Play Store?

Hi,
When u install siyah kernel, it includes the cwm app with the kernel. And the app is the same app you get in the cf- root kernel.
Siyah kernel is by far superior to cf-root. If you set it up right, you can get much better battery life. And it is so smooth. I would recommend that u use siyah..
Cheers

If you have siyah kernel installed, you can download an application from the play store called "extweaks"
If you open that you will find the option to under volt the cpu

Ps
And also, if you want really good battery life, go in to cwm recovery, go to "kernel specific options" and click on "battery optimised" that will set everything to get you the best battery life.
