Hi!
I installed Icecream sunday mod (which is great btw) but I have an issue with fm radio (it enables bluetooth and also outputs some noise loudly when starting.
I saw that there are some issues in cyanogen related to some kernel version (coolya kernel). I also read that there is a ketut kernel. I am kind of lost in this kernel stuf... Which are these? Where can they be downloaded? Doesn't these mods include the entire kernel already? How can I find which kernel version I am running? I found that many kernels (including stock) are called by abbreviation (which can be confusing)...
Is the mod performance/stability impacted by the previous firmware installed (stock kernel version)? Which parts of the original kernel stay and which are overwritten?
Sorry for the newbie post but I could not find this anywhere...
I don't remember but I think Ice Cream Sunday use Ketut's kernel.
You can find your actual kernel at Settings>About Phone>Kernel Version

as jusada said default one comes with ketut's kernel...
previous firmware does not matter much modem/radio/baseband are things that are used from them.. if anything is unstable like signals then you can flash other radio...
as you can see zip file contains boot.img to be flashed its thing which changes kernel stuffs

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?
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.
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
I want to inlclude latest Siyah Kernel incl. CrtOff and 3Way EPM into OmegaRom v37.
I extracted both Roms and copied/overwrote boot.img and flash_image in Omega /indie/ with the Siyah ones. Then I compressed the files again, put them on my exSDCard and flashed the image.
It seems to work. Did I forgot something to change/include?
What's the question?
The question is in the third line of the first post. You should add "Hit me if I deserve it in your sig."
As you are hacking Indies rom why not ask him .
It also looks like you have used and posted a devs work without any indication or probable authority from the dev .
jje
If you want to install the latest X-kernel (or whatever mod) in Omega the best thing to do would be to install the ROM and then come to our forum.All compatable kernels and mods are avalable in the Omega files kitchen app that comes installed without all this fuss.Hit my sig below and come to the forum.
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
