Hey anyone that's got some noob time, I was curious what exactly is a kernel, why are there different kernels, when to know if you need to use a different kernel and lastly instructions on how to flash a kernel. I am pretty experienced in dealing with my phone and I'm capable of bringing my phone back from ANY software brick with ODIN and I have been flashing ROMS for about 5 months. I recently was reading up on the Epic 4g forums because I was going to root my epic when I buy it and I noticed much more about kernels in the epic 4g forums. Any knowledge would be appreciated! Thanks!
Roms, Basebands and Kernels, a basic overview
The baseband is only the 'radio' part of the phone that makes the calls, the 3G and Wifi connections, GPS connections, etc. As you thought, it is totally separate from a ROM. Updating a ROM will not update a baseband and going back to an older ROM will not 'downgrade' the baseband either. Upgrades to a baseband my improve signal strength, call quality, maybe have software tweaks to improve battery life while on 3G/Wifi, etc - things like that.
Kernels are the core software code that allows CPU to over-clocking and controls voltage controls. Think of it like Bios settings on your computer (PC, that is)..that's really all they do. Now, a kernel can be completely separate from a ROM, but a new ROM contains a kernel in it so it will run. So, a kernel can be both separately applied from a ROM, but is also part of a ROM.
The ROM is basically everything else but the apps and the two things above. It's actually the OS, as well as any stock apps that come with it - and any new improvements, features, etc. The increasing build numbers reflect bug fixes, known issue solutions, feature improvements, etc...thing of them like windows service packs and/or any software update.
Some of the other phones modifying the kernel may be done more because the phone design and limitations
Hope that helps
Very helpful, I was sure to click thanks. I'm curious how to change the kernel on my phone and when should i consider changing it. Do I use ODIN to change the kernel? Also can any kernel work with any ROM? If not, how do I know which ROMs a specific kernel is compatible with?

Most kernels can be flashed just like a ROM, very few require ODIN and if it does the dev will specifically say so. Also not every kernel works with every ROM. However they are usually made to work with any ROM base don a version number. For example if a kernel is made for 2.2 than all ROMs that are made from 2.2 will work with it. The version number a kernel is meant to be used with is always in the OP of its thread.
And one last thing, if it is a kernel that has to be flashed via ODIN could someone give a step by step? I've got return to stock via ODIN memorized and I've done it plenty of times but not sure about the procedure for kernels.
Put the kernel in the PDA do not repartition, On a side note, when you are flashing things especially adding new kernels etc, It is better to go to recovery manually and do it from there. Sometimes the custom stuff or CWM have conflicts and it doesn't flash and you have to go odin back......... that's been my experience
so just use adb to get to stock recovery and then choose install packages? forgive me for my extreme detail

Have you been using 2.2.1 ROMs?? I always have to ODIN from 2.2.1 ROMs cause I can't wipe data from CWM on them. So when it gets to that part of flashing the ROM it freezes

New SG2
Home home, it was running 2.3, did a OTA check, it said 2.6 was available. Didnt do it, researched on here first. Noticed alot of battery issues with it.
Rooted with superoneclick.
Flashed Sihyah kernel with odin
Flashed STOShock
Flashed ICS Theme
Charged to 100%, wiped battery stats
Now its my first day running the phone. The battery is really sucking right now. Its been dropping like 1-3% just when i reboot the phone. Seems to drop about 5-10% an hour of the phone doing nothing/turning screen on for 1-3 minutes a couple times to check notifications every hour. I checked wake locks etc, nothing is holding it up.
Now i noticed the version of the system is UCK6 and the kernel is 2.6. Dont these versions have problems?
Is there any other suggests Kernels or roms to flash? I'll even goto a stock rom if its battery life and performance is near the top for all roms. All i really care about is a solid stable long lasting phone with a ics theme and having root.
Perhaps the crappy battery could be from this being my first charge too and the battery not going through any charge/drain cycles yet?
there is no version 2.6 for android....
kernel version and android version are not the same thing. 2.6.x kernel is normal for EVERY version of gingerbread.
what you need to do is have a look at the threads, specifically one called [REF] Known identified battery drainers and check at what apps are eating up your battery.
Doh, what i meant was 2.3.4 to 2.3.6 i believe. And i followed that thread, there are no wakelocks keeping the phone up.
Maybe a better question is. Should i be running UCK7 and not UCK6? Im reading it has some wifi bug that drains down and i use wifi alot
Im thinking of maybe going stock. As long as i can be ics themed.

shostock is a great rom, i have had excellent battery life.
try unnamed 1.3.2 and see if it works out better for you.
Alright ill give that a try i suppose.
Does it matter that im running the latest Siyha kernel? I dont have to reflash any kind of different kernel do i?

a kernel will be included with the rom.
you can flash any kernel you like, but it could be whats causing your battery issues.
I see, i thought you had to flash a custom kernel first before flashing a rom. Because on the SHOstock page for installation it said "You must be running a kernel with CWM."
So i thought i needed to flash a kernel first.
But anyway, if roms include kernels, which im guessing the rom is optimized specifically for that kernel thats included. Whats the point of having them seperate to flash? So you can run a different kernel for some reason after you flash a rom thats using a different one?

You only need the kernel beforehand for CWM. The mentioned roms have kernels included in their package, so it'll be changed upon flash. After flashing the rom, you then have the choice to change to the kernel of your liking. The kernel included is typically the developer's choice for what they think is the best for their rom (perhaps PirateGhost will chime in on this part). Your experience may vary though, which is why you might change to something else.
Gotcha, totally understand. I looked around trying to find a thread that explained the different Base versions.
UCKK6
UCKH7
GWK74, etc,
Im trying to understand the order of oldest to newest release, and what the differences are.
Also, im guessing these bases are official samsung coded items right?

Hey guys, I'm not gonna ask the dreaded question "Which Kernal is best?", but I am currently rooted and want to overclock to 1.5, but besides that, what else should I be looking for in a kernal?
What about modems (or is that embedded in the kernal)?
We only have 2 options, Entropy or Siyah and they do not include a modem.
Check the dev section for kernels & modems.

Both kernels we have offer oc abilities.
Personally I would look at stability and battery life but that is just me. Try both and see which suits your needs.
Modems are not associated with kernel and depend on your area. Whichever works the best where you are.
We have two choices here and both are incredibly stable and allow overclocking. You can't go wrong. Basically the biggest difference as far as I can see is the recovery that comes with it which is almost entirely preference.

So if I find a ROM I like but want to experiment with the other available Kernal, is it as simple as flashing my ROM first, then once booted up go into Odin and flash the other kernal i want to experiment with?
Or is the kernal that comes with a ROM the one your stuck with?

Just use CWM to flash the zips provided or Mobile Odin if you prefer it that way.
No need to use a computer to change the Kernel.

Thanks for the quick response chris,
I guess what I'm asking is if I have a rom with the Syiah kernal, is it possible to keep that same ROM but swap kernals, sorry, I just wasn't clear on what your answer meant.
I'm guessing your saying it is indeed possible and just flash the .zip for a different Kernal on top of an already installed ROM.
Sorry, I'm tired...
Changing the Kernel on 2.3.4 & 2.3.6 roms will not break anything.
For CM7, CM9, MIUI etc you have to stick with what is included or see what works with it.

For example, latest Siyah with touch recovery. Awesome for flashaholics.
Your talking of version .14 I assume, if so, doesn't it say in .13 description that .13 would be the last for Gingerbread?
Obviously it works if your using it, so i'm gonna download now...
Okay so I am sort of confused between what a Rom and kernel is. I have flashed saurom rom rcvi on my phone and it comes with a kernel.
I just want to know what they exactly are.
I know a rom is basically like the operating system and their are different roms. What is a kernel tho? I have dags oc kernel though i havent oc yet. But what is it and what does it do? I assume it has something to do with the internal hardware and performance. How do you flash a kernel by itself, Can you even do that or does it always come coupled with a rom? Lets say i wanted to get the holonote kernel by itself would it be possible to do that? Can you mix and match roms and kernels?
Also where does theming come into play? I know that theming well basicallys themes and decorates your device. But how does that work? Do certain roms have themes, or can you put any themes on any roms? How do you flash a rom? Also themes shouldnt affect the performance right.
You may want to search the forums, specifically Q&A or development. People are going to flame you.

http://en.wikipedia.org/wiki/Kernel_(computing)
In the simplest terms that I can think of, a kernel is a component within an operating system that acts as a bridge which allows software to communicate with hardware. I think Saurom is bundled with Hololight's kernel, and the two Collective roms are bundled with DaG's 0.2 OC kernel. You can flash an alternate kernel, as long as your ROM works with it. You can also flash just a kernel without flashing a ROM.
As for themes, most of them are designed for and require a specific ROM. The thread for the theme will be very clear as to which ROM is required to run it.

Follow up to OP's question: Where does the kernel "live"? Is it in the boot partition?
I ask, because with all the flashing and at times wanting to go back, does a full nadroid restore (I see it restoring the boot partition, then system, then data) restore the previous kernel also?
Thanks.
If you are curious where stuff is... Take a cwm flashable zip, open it with 7 zip on your pc, follow the folder path in "meta-INF" til you get to a file called "updater-script" pull that out, open it up with NotePad and look and see where its writing to.
the kernel is written to

I recently picked up a GP 4.2. I immediately got it rooted so now I'm running a 2.3.6 stock rom with root. What's the next step in terms of getting a recovery installed and maybe moving up to an ICS or JB rom? I've kind of poked around a bit but it's some what confusing with all the other types of GPs in the same area. Does anybody have a recovery and rom they'd recommend? Is using rom manager to push CWM feasible?
I would recommend the ChaOS ROM/Kernel which includes CWM. It is one of the few available ROMs for this device right now but offers a lot of great features. You can also install an S3 or Jelly Bean theme with the ChaOS ROM. Here's the link to the ROM: http://forum.xda-developers.com/showthread.php?t=2279806. I do not believe using ROM manager to push CWM is feasible on this device. Also, CM7 will most likely make it on to this device very soon. I would recommend watching for that in the near future. I know it can be a hassle trying to weed through the Galaxy Player forums to find 4.2 information but it's all we've got. Hope this helps and welcome to the SGP 4.2 community!

Thank you for the info Meta. I'm somewhere around the mid-high mid level with flashing and rooting but slogging through trying to find the right info for a GP 4.2 was getting a bit hectic. I think part of it was the way some people abbreviate the model compared to others. I just wanted to make sure I didn't brick the device.
I got it mainly for a perm, in-car music and GPS/navigation provider instead of always looking to my phone to do it. One thing I noticed about the rom, it mentions installing it via CWM. If I don't have CWM yet, can this rom get pushed by odin or do I have to get CWM first and then flash the rom?

Ok thanks. I also have a question regarding flashing kernels. In the linux world (and other os world), randomly changing your kernel is a big no no that would lead to major compatibility issues. I don't understand how people can mix and match kernels, roms, firmware, bootloaders, recoveries and everything else? There won't be conflicts?
Regarding the kernel available for the 3.6: what do I do if I encounter stability issues with it and, say, the upcoming CM7? I wouldn't be able to go back to my original kernel because I didn't have CWM to back it up in the first place. Won't I be stuck with a potentially faulty kernel?

In changing kernels in the android world, you have mixed results. There are times a kernel can cause some issues but for the most part (we're talking like 98%), if an XDA dev posts a kernel and lets you know you can use it, you can trust it. These devs no matter the device spend painstaking hours ironing things out. Also, many of them have a select group of people testing the kernel for faults and issues. In a very active community, if a well known dev posts a kernel, you can trust it. HOWEVER...no matter what we think or believe or what we're told, every device is a unique and beautiful snowflake. Back up back up back up BACK UP BACK UP BACK UP your stuff. If you want to be super ULTRA safe, take the back up and download it to your PC or somewhere safe.

Ok thank you. However, will this work with YP-GS1?
But about kernels, on the webpage where I downloaded the stock rooted rom http://tau.shadowchild.nl/attn1/?p=166 it says specifically that the Wifi module in system and kernel must MATCH. This is what I'm talking about in regards to kernel compatibility with roms. How do I know if a kernel I'm downloading will have changes applied to it that will work with another rom like with this stock rom/kernel?
Well in order-I used odin to flash CWM. Once it rebooted, I saw the Galaxy SII boot anim. Used Rom Manager to have it boot to CWM. From there I flashed wifi fix, the rom and then the mod pack. My build number is gingerbread-ueld3. From what I can tell, I think I'm all done. At first I was like hrmmmmm. Doesn't look much different. When I hit the toggle bar though, I could tell it had changed. The process was all very simple after I got headed in the right direction with CWM. That was my only confusing start point for this.
Edit-my bad. The rom didn't take on the first flash. I could tell by the build number. Reflashing the rom and the s3 addons. Hrmmm. Might be boot looping. It's going through the comet and coming up to the white samsung, vibrates a few times after a bit and goes back to the comet with no sound.

Poop. I think I bootloped the sucker. I can use Odin to reflash the stock, rooted rom just like I did when I got it first rooted right? Do we have another rom for the 4.2 I could try flashing? Not sure why it has bootlooped. I even went back into CWM, did a factory reset, flashed only the rom (no addons) and same thing. Possible bad download? It is flashing from the internal SD as my CWM is not seeing my external SD.

I have been meaning to post this on the dev thread for awhile. I thought this problem might only be for certain people but I think it applies to US and maybe non-EU devices. I believe that the ChaOS ROM will bootloop on US (YP-GI1/XAA) devices if you do not install ChaOS's Enhanced Stock ROM (http://forum.xda-developers.com/showthread.php?t=2279450) for whatever reason. I spent days trying to install his ROM and bootlooping.
The way I successfully installed (if I remember correctly):
-Do a factory reset of rooted stock ROM
-Boot to CWM (meaning you have already flashed the custom kernel) and install ChaOS's Enhanced Stock (put all install files on internal SD)
-Boot to CWM, wipe davlick cache under "advanced", wipe cache partition, and install the ChaOS ROM
-Wait a little while and your device should boot up properly
I hope this works for you. If it doesn't let me know and I can help you further. If this does work for you too then I will post this on the ROM's thread for other users.

SerkTheTurk said it very well, you do not need to worry, but if you also want to do a backup before you install the custom kernel you could use the adb tools on the computer to backup the device. I'm sure you could learn how to do that with a quick Google search.

I have been meaning to post this on the dev thread for awhile. I thought this problem might only be for certain people but I think it applies to US and maybe non-EU devices. I believe that the ChaOS ROM will bootloop on US (YP-GI1/XAA) devices if you do not install ChaOS's Enhanced Stock ROM (http://forum.xda-developers.com/showthread.php?t=2279450) for whatever reason. I spent days trying to install his ROM and bootlooping.
The way I successfully installed (if I remember correctly):
-Do a factory reset of rooted stock ROM
-Boot to CWM (meaning you have already flashed the custom kernel) and install ChaOS's Enhanced Stock (put all install files on internal SD)
-Boot to CWM, wipe davlick cache under "advanced", wipe cache partition, and install the ChaOS ROM
-Wait a little while and your device should boot up properly
I hope this works for you. If it doesn't let me know and I can help you further. If this does work for you too then I will post this on the ROM's thread for other users.

ell there's not really much point in backing up the kernel when I've already downloaded it on my computer.
I've since flashed KingOS rom and don't really notice any differences at besides a few color changes... what's all the hype about?

Xen-it seems GPlayer development is still fairly newish. the work you see from devs now are all ground work. For the 4.2 and 3.6, they seem a little less dev populated than the 4 and 5. People will build upon the work of early devs and eventually get kernels that can OC and maybe ICS and JB roms. At this stage, we likely won't see anything like ZOMG earth shattering until people spend time with the devices. Seems Serk is on his way to doing the best he can for 4.2 but I am not sure who is tackling 3.6
It's weird how roms for devices go. I learned this when I had a tbolt and shockingly saw a FUNCTIONAL JB rom for my old Eris while the tbolt was still hanging back in ginger land with not even a really good ICS rom let alone JB. I asked the Tbolt community-why? How is it the dinosaur Eris has JB and not us? It all depends on what the devs can do with the sources provided. Sometimes certain hardware points are sticky. you can have beautiful JB rom for a device that can't talk to the camera if the hardware source isn't made available (reference the HP TP for many years)
For now, flash what you're comfortable with and and learn what you do and don't like. Also learn if you want to play things safe and not experiment or take on potentially beta builds. For the tbolt, tackling an ICS rom was too dicey so I never did. On my new Rezound, I eat up JB roms as they are in much better shape
If I was to install, say, the Liquid Smooth ROM onto my i717 (I have a good amount of experience with flashing ROMs, so that much I know,) specifically, the KitKat version, it lists kernels in the download links. Would these kernels be included with the ROM files themselves, i.e. install at the same time as the ROM, or would I have to flash the kernel separately before flashing the ROM? Thank you VERY much in advance

The thread should tell you if the kernel is baked into the Rom our not but the stock kernel usually comes with it. I'm pretty sure you're talking about a beefed up kernel tho. You'll just have to read the thread and if you're still not clear about it, ask in that thread to be sure.

there is always a kernel included with a rom. most alternate kernels are made and or flashed to combat a side effect or incompatibility with some folks devices. its not that provided kernel doesn't work, just that every device is different and the alternates can sometimes be more compatible.
however, I would suggest you give the original kernel a chance to settle, at least a day if not two. if it just flat out is not working for you, then flash an alternate onto the rom. wipe you caches ( not factory) flash kernel by itself and your good
never want to discount reading here as Gimmeitorilltell suggests. reading educates you and puts you in a better position to help yourself first.

In general stick with the kernel that comes with a ROM unless you have a reason to change, like stability, overclocking, etc... but you do flash the kernel after the ROM; anytime after the ROM flash really. You don't need a clean flash before kernel switch.
The dev probably did not test his/her ROM with every kernel possible so if you want support your best bet is to be on the kernel included. For the 1st install of a ROM if you are unsure you should definitely use included kernel; as sometimes you just can't predict what changing it will do.
That said there many of us do switch kernels when installing updates, I certainly do. There are not alot of kernels for our phones as only a dedicated few devs continue to support the Note but you have a few choices. All kernels I've seen allow performance/governor control to some degree. If you read through the various ROM threads you'll find that some kernels are preferred by users but for the most part kernels like Uber work well with most ROMs.
P0llution's ROM patch allows you to switch kernels after flashing a ROM (BeanStalk, LiquidSmooth, etc....) and even before 1st boot. It also has patches for various KK problems. It is in the Beanstalk thread 1st post.
Thank you so much for your replies! Installed LS and flashed Uber kernel and running with no issues.
