hi guys,
i wanna ask you senious guys that,should i have to change the kernel each time if i want to change the ROM of my galaxy s II or any kernel will work with any ROM?
kindly assist me in this matter.thanks.
What type of Rom are you trying to flash?
Most custom roms include a kernel so you you will have to refresh back to your preferred kernel.
Or you can open the zip file and replace the kernel of your choice as long as it matches your firmware version, ie GB kernel for a GB rom etc.

any kernel may not work with any ROMs...almost all samsung firmware versions has got its own versions of Kernel.
In SGS2 normaly custom kernels are used for rooting your phone, like CF-root, whcih are made for almost all the samsung firamware matched kernels, you only want to pick the one matching for your ROM.
It is also seen sometimes advised to back up your Kernel, this can be done using a tool from Market called "Ktool", at a worst scenario, when your installed custom kernel giving you a treble you can restore the previous one.
EDIT : you are already on a custom ROM as well as Custom Kernel. both have got their newer versions alredy.
checkrom is now on V6, and Siyah kernel is now on v2.6.14
Well your still on gingerbread and an early kernel and early checkrom. There are many roms and kernels you can try the best for battery life us what works best for you and only you can figure that out with testing.
Try out an ICS Rom if you haven't done so already and there are now custom kernels for that as well.

On xda there are many roms with included kernels. Resurrection Remix v1.1 is my personal favorite ICS rom at this moment, with stock kernel battery life is very good. Just search on xda

I meant the kernel that is already included with the rom when you flash it. So just flash the rom and you don't need to install another kernel after it.
Here is a link to the Resurrection rom:

Hope this helped you
If you flash a rom it replaces the kernel you've been using with that of the rom you're flashing...
Soooo
Eg cm9 + siyah
If you flash a new nightly it'll replace siyah with cm9s kernel so you have to flash siyah each time.
Think that makes sense..!

I have a noob question regarding flashing a custom ROM with the HOX+
1) Do I always have to flash a kernel when flashing a rom? If not or if so what are the benefits of doing this.
Thanks all. I look forward to being able to help other users as I lean more.

from my experience with flashing a few ROMs, the kernel, usually but not always, included in the ROM.
some ROM like AOSP/AOKP for our device don't include the kernel.
I'm a noob myself so dont take my words for it :laugh:

You don't need to flash kernel every time you flash custom ROM as long as your kernel is compatible with the ROM. For example: if you already flash nik3r's elite kernel, you can switch to every sense ROM without flash kernel again. But if you want to flash AOKP/AOSP/CM ROMs, you need to flash spesific kernel, which is maxwen's blade kernel.
Thanks perfect explination
hi everyone.
well, i've searched a lot about kernels in different threads, but didn't find any detailed and comprehensive information about kernels.
i rooted my SGSII with Odin through a guide which installed Siyah-s2-v6.0b4.tar kernel and CWM based recovery on my phone.
i flashed RootBox-JB-i9100-V4.2 ROM and now have 3.0.64-CM-g32f12dd kernel.
Before i flashed a custom ROM i got stweaks working, and after i flashed rootbox i recieve a message:"no kernel support" on stweaks.
This is leading to my first question- does my kernel change when i use different ROMs?
now i want to try and change my kernel to one who is supported by stweaks and has touch CWM and works with RootBox, but i'm not sure how to flash kernels.
This is leading to my second question- can anyone describe the whole procedure of how to change kernels on SGSII?
thanks for your attention.
There's nothing to describe. Custom kernels are flashed in CWRecovery mostly (some have Odin flashable versions as well). Always follow the exact flashing instructions for the kernel in question which are always on the first page of the thread devoted to the kernel in whichever development section, and are always very clear/simple to follow.
Only some kernels like Siyah or DorimanX support STweaks.Look up here on S2 forums in the Android Development section for kernelsThere are some others that have STweaks support.Also,.don't flash kernels made for Sammy ROMs.If you wanna flash DorimanX, then flash 9.39, not 8.39.

Yes, if the ROM comes bundled with its own kernel(s). :good:

1.Just go the kernel thread you want to use.(Mind that you cant use siyah with Rootbox). Search for a kernel which supports 4.2.2 (eg. Dorimanx 9.x) and download the CWM Flashable zip in the thread.
2.Download Hawker Paul`s Kernel Cleaning Script
3.Flash Hawker Paul`s Kernel Cleaning Script first trhu CWM
4.Then Flash the Kernel ZIP
Hit Thanks if I`ve helped you
thanks everyone! you're great!
absolutely clear now.
So I've tried a bunch of different ROMs (CleanROM, Alliance, Beans, CM, OMNI, "Stock", probably more), but I've never really understood kernels. It seems some custom ROMs have a kernel built in (or several to choose from via Aroma), while others do not. Right now I'm running AOKP (4.4.2) with the kernel from OMNI (3.0.64-OMNI-g5f47648), presumably because that was the previous ROM I flashed with a kernel. I'm not too concerned with customization, more with stability.
I've been having a few minor bugs and crashes and I'd like to try perhaps the stock kernel to see if that might help, but I have some questions:
1) Does it matter when flashing a kernel whether the ROM is TW or AOSP?
2) Are there multiple versions of kernels that correspond with the Android version of the ROM?
3) What's the best/easiest way to flash a kernel, presumably through the custom recovery like a ROM?
4) Where can I find the stock kernel? I found this thread (http://forum.xda-developers.com/showthread.php?t=2610870) with the stock MJ9 kernel, but going back to my first two questions I'm not sure if it would work with my current ROM.
Thanks ahead of time for any insight anyone can provide.

1) Does it matter when flashing a kernel whether the ROM is TW or AOSP?
Yes. TW and AOSP kernels are different.. The only one, that I believe, that can be used with both is Devil kernel for Dual Booting
2) Are there multiple versions of kernels that correspond with the Android version of the ROM?
Yes. Usually every version of android that gets updated.. the kernel does as well
3) What's the best/easiest way to flash a kernel, presumably through the custom recovery like a ROM?
Yes you can flash kernels through a custom recovery. Most of the time they are included with the Rom that you flash. A lot of the custom ones out have flashable zip for you to flash them through a recovery.
4) Where can I find the stock kernel? I found this thread (http://forum.xda-developers.com/showthread.php?t=2610870) with the stock MJ9 kernel, but going back to my first two questions I'm not sure if it would work with my current ROM.
No this will NOT work with a AOSP rom.. The kernel will be specific to that ROM and every other TW 4.3 ROM, but NOT AOSP

Thanks for the explanations, that helps tremendously. I'm confused now, however, because several people on the AOKP thread (http://forum.xda-developers.com/showthread.php?t=2453566) claim to be on "stock kernel". Is there a stock kernel for AOSP that I'm missing?

Well that's what I thought, but why then would I be using an OMNI kernel (3.0.64-OMNI-g5f47648) when I have flashed the last three AOKP nightly ROMs that have come out? Or am I missing something here?

Maybe he uses that kernel.. AOSP kernels, I believe are pretty similar.. I may be wrong, I am by NO MEANS a kernel guru..I would open you zip of your ROM (AOKP) and take a peak.. if there is a boot.img than it flashes a kernel.. and if your says OMNI then thats the kernel the dev has used..
Stock
If I'm on the stock rom and want to go back to the original kernel can I just restore the boot img in recovery?

Thank you sir. It worked just fine.
I have a noob question, I'm currently using n3bula 3.9 custom rom and it's been running fine for a while. I noticed that users chose the agni kernel whereas I chose the stock one. So my question is, is it possible to flash just the kernel from recovery without losing my data? I've spent so much time and effort customizing my phone, therefore, I just want to change the kernel. Any help will be appreciated. Thanks.

I would think that as long as it doesn't break anything you should be fine. Probably do a backup first if you're worried about it.
Thanks for the response Michael, however, that was the response I was dreading! I'm actually worried I'll lose my WhatsApp and Viber accounts because even if I backed up my data, I'd still have to register my old WhatsApp and Viber numbers all over again which I don't have anymore.. ??
Hi,
I wish to install a newer ROM than the one I currently have, yet it seems I might need a new kernel and CWM instead if TWRP.
So my questions are:
1. How do I know if I need a new kernel?
2. At some kernel threads, it is said that they only work with kitkat ROMs for example, and other ROMs might brick the phone with this kernel.
So do I flash a new kernel first or a new ROM first? Basically, how do I not brick my phone?
3. I read somewhere that SGS2 users can't install recovery without installing a new kernel. Is it true?
4. I would appreciate some directions about installing a new recovery (I would probably need CWM).
5. Why is it so hard to find answers to these probably many times asked questions?
Thanks.

1 - if you are happy with your current rom, dont flash a kernel if not sure what you are doing!
2 - kk and LP kernels are not compatible between them as your cpu doesn't fit in a incompatible motherboard ! newer kernels are safe from brickbug ! you wont brick your phone with a wrong kernel (kk kernel over LP rom), just a bootloop.
3 - because a kernel is a recovery and a recovery is a kernel.
4 - Slimsaber is a good rom to start see first and second post
5 - is not hard to find if you know were to look!

Just a small correction. A recovery (CWM or TWRP) can not be installed by itself because we don't have a recovery partition. Therefore kernel with a custom recovery needs to be installed.

1. I am happy with the current ROM, yet I want to flash the kernel to fix the annoying FPBug and to finally get LP ROM. And I might not know what am I doing, but if I won't try I will never know
I've flashed a new kernel and a new LP ROM, and I'm trying some others.
I still find it difficult to find a kernel that answers my needs since many kernels are hiding in specific posts and some kernel threads doesn't mention which recovery they install.
