I've always used which ever Kernel come shipped with the ROM, until FroydVillain 1.5.0 gave the option to download the kernel separately.
I have since learnt that you can pretty much choose any kernel with any ROM as long at its compatible.
What are the rules for this?
How do you know which kernel you can use with which ROM?

Hello everyone!
I have a simple question that I would like to have answered. I'm adept at running custom ROMS on my GTAB, but I've never really messed with kernel stuff before.
There isn't exactly a 'topic' that deals with this, and pershoots website doesn't have that much detail either.
So I would like to know what kernel would be the best for me to run.
I've got VEGAn-Tab GingerEdition running and I just installed pershoots 2.6.32.39-cyanogenmod and it should be the ginger edition
Is this the right kernel or should I be running another?
Thanks
There are basically two kernels that are being actively supported on XDA, pershoot's and clemsyn's (clemsyn has several kernels out, but they're all just slight variations on the same kernel). If you want to overclock above 1.4GHz and/or adjust the voltage settings, then you should try clemsyn's. If not, then stick with pershoot's. It's what I use. It's what most of the devs on here include with their ROMs. For me, it seems to run better with less work. But try them both out for yourself and see what you like better. That's the only way you can really know if you're running the "right" kernel.
Also, pershoot just updated his kernel to 3.6.32.40, if you want the latest version.
Froyo use clemsyn. Gb use pershoot. Jmho...
Hey Thanks! This stuff gets quite confusing.
Another question here. I have installed Roms but how do we install a Kernel? Do we install prior to the Rom?
Thanks in advance
I've tested out every version.
1- froyo -->clemsy
2- ginger --> pershoot
3- flash kernel as you would with any other zip file. Do not use calk wipe all zip.
Hi All,
I searched the forums and though this question has been asked couple of times, I failed to get a satisfying and consolidated answer, so seeking a solution here.
Scenario: X10i, 2.3.3 Stock, rooted using aZuZu. Self-customized framework-res.apk and SemcUxpRes.apk and a truckload of apps. Poor battery life, slightly laggy.
I am equally drawn towards CM7 as well as Wolfbreak 4. I know that both are completely different flavours, but much as I love the Cyanogen innovations, so do i love the tweaks done in WB's ROM with minimal changes to the UI.
Questions:
When I backup my current ROM using xrecovery, what all elements get backed up? More precisely, if I make a backup of my stock ROM using xRecovery, will it backup all the installed apps, conntacts, messages and appdata?
If I restore this backup at a later date, will I be able to get back my phone in the same state as it was backed up? (e.g. I am on level 14 on angrybirds and I made a backup, wiped my phone, and then restored the backup, will I have to start Angrybirds afresh or I can continue from where I left off, as though nothing had happened?)
Is it possible to have multiboot on the X10? So that Everytime I boot up, I can choose whether I want to load the CM7 ROM or the WB4 ROM?
Thanks in advance.
1 yes, the things you mentioned will be backed up (but not the baseband & the kernel)
2 yes, you can play angry birds from where you left off (but as I said you can't backup/restore baseband & kernel)
3 no, not yet. Before official gb there was a solution for dual booting a 2.1 rom with a 2.2/2.3 rom, but I believe dual booting two 2.3 roms is not possible for now

Thanks for that! Just a couple of doubts here:
As you mentioned, the BB and kernel wont be backed up. How exactly will that affect my device? Will it lead to any compatibility issues if I restore to a backed up ROM?
Do I need to keep a note of the Baseband and Kernel versions of all the ROMS which I intend to flash, and flash the corresponding bb & kernel versions prior to recovering a backed-up ROM? To be more clear, supposing I am on bb .71 and kernel 2.6.29, and I flash a new ROM with a different kernel. If I wish to go back to stock by recovering my backup, will I have to flash the bb .71 and 2.6.29 kernel again?
I noticed Woflbreak's ROM uses kernel version 2.3, but I am on a different kernel version (2.6.29). Do I need to downgrade to 2.3 kernel before using the WB ROM? Won't an older version of the kernel cause a drop in performance?
well to sum it up yes you need to keep a note of kernel & baseband for avoiding any compability issue, the kernel part is pretty easy, 2.1 roms all use the same kernel & 2.3 roms another kernel, If you want to go from a 2.1 rom to a 2.3 rom you need to flash the appropriate kernel (& the baseband) with flashtools, but switching from a 2.1 rom to another 2.1 rom or from a 2.3 rom to a 2.3 rom shouldn't be a problem kernel-wise, you just need to pay attention to the required baseband & flash the right one if necessary
what rom are you on?
& by the way 2.3 on Wolfbreak is not the kernel, it's the android version
the bb and kernel are in a 7zip archive linked on the page for wolfs 4.0 along with the newest patch. it explains how to do it all on the page. You must take into consideration when trying a new rom the basebands that it is made for.
Basebands can be found here.
Most newer roms will tell you in the post which baseband you need.
Also see if users post other working baseband versions along with kernel versions. how to use a custom kernel with it and a post explaining custom kernels is here.
Ok so i am sure this is noob question I am currently running the latest doom kernel and the T.E.A.M ROM v1.6. My question if I change ROM do I need to go back to the stock kernel first? If so were can I download it i think I found a thread with a list of Kernels once but can't find it again.
Hello
I'm new to this...
I was wondering if I can install the SpeedMod Kernel on my SGS2??
Why this Question:
When I rooted my decive with cf-root and odin I have chosen the Kernel with the same "version" my stock kernel had.
Now I'm not sure if I can install any sgs2 kernel (in this case SpeedMod) or if the "version" is important.
I think that all SGS2 Phones should have the same hardware so I sould be able to use any Kernel. Is that right?
What do I have to be aware of, when I choose a new kernel?
Thanks
Ditschi
Yes you can, don't worry about it. Versions don't care much after all.
Thanks a lot thought that. I'll flash he kernel tomorow.
But what im interested in:
When you say the version doesn't matter why are there so many versions of cf-root? Is'nt that a lot of extra work? Why not useing only one kernel?
Cheers
Ditschi
That's for people who want to stay as close as possible to stock.
The developers compile their kernel to work with any Samsung or TouchWiz based rom.
CF Root extracts the kernels from the specific rom, adds in the goodies and presents it to us for use to root the respective rom. So basically what you have is the stock kernel with root added among other things
ah ok...
That makes sense. Thanks a Lot for the help
Hi all,
I want to know if a rom always contains a new kernel and can you change the kernel without changing to another costum rom?
I'm sure most ROMs come with a kernel that is tweaked, at least a little. That doesn't necessarily mean it will support oc/uc. and yes you can flash a kernel, if compatible with you ROM, at your leisure.
there is no spoon.....
Almost all roms come with a kernel of some type, but I feel like I remember seeing a rom a few months ago that didn't come with any kernel, so you had to flash one right after you flashed the rom before booting up (that's what the dev said if I'm remembering right, I didn't flash the rom).
And yes, you can flash any kernel at any time as long as it is compatible with your device/rom.
Well... if the ROM doesn't contain a kernel (that's kind of common) your previous kernel is retained.
This applies specifically to stock-based ROMs
