Kernal ??

Is it necessary to flash a Kernal after flashing a custom rom ?
I am thinking of flashing CM 9 or Liquid Rom. Which is the best kernal to flash with them.

-The correct spelling is kernel.
-It is not necessary to flash a new kernel with a rom. In general roms will package the stock kernel unless they note otherwise.
-I am personally a fan of leankernel because of the mission statement behind its development and the accessibility and speed of its update cycle.

Nope. Custom roms have kernels included, so you are not required to download a separate kernel. However, some kernels run better (ie, more fluid, less heat, reboots, etc) than others on the same device. It all depends on the silicon in your phone. If you plan to run cm9, I recommend sticking with the default kernel. If you're going with Liquid, use imoseyon's leankernel (the default) or franco kernels.
Edit: BTW, I highly recommend franco's kernel app, especially if you are new to the scene. It can download & install either franco or imoseyon kernels, making kernel flashing stupid easy. It also lets you overclock & undervolt, change governors and tweak color settings. And it is the easiest way to keep up with nightly/experimental builds. Not to mention it shows your support and encourages more development.

i say try them all, but for cm9 i recommend fugumod.

Thanks you all for your suggestions ...
finally going to try Liquid Smooth 1.25 (http://forum.xda-developers.com/showthread.php?t=1555667)
along with Franco.Kernel (http://forum.xda-developers.com/showthread.php?t=1367341)
...... One last question Which Franco Kernel to flash there are Milestone 2, Milestone 1, Nightly ??? Whats the difference between them ?

Also when installing extras for liquid smooth do i need to wipe everything again .. I am new to this flashing stuff
and does Liquid Smooth comes with a kernel if so which one ?

Latest milestone is the most stable. Nightlies are experimental. And no need to wipe.

Liquid + franco is a great choice. Liquid is an extremely polished rom. Very, very smooth with absolutely ZERO lag (it is called Liquid Smooth for a reason) and lots of customization & tweaking options. franco kernel pushes the smoothness to another level. Liquid & franco are both awesome devs who have been tinkering with android for a long time, and they both know their stuff.
Liquid comes with imoseyon's leankernel, which is a solid kernel (obviously, or Liquid wouldn't have included it in the rom). imoseyon is another well-known & respected dev that churns kernels at a dizzying rate. He must develop in his sleep. A lot of people prefer his leankernel, and you really can't go wrong with it. But like I said before, it really depends on your device. Your phone picks the kernel, not you. Milestones are the most stable versions. Nightlies are bleeding edge experimentals with the latest patches & tweaks that may or may not improve battery or performance. Since you are new to flashing, you might want to go with milestone 2 for a few days and see how it feels. On the other hand, you could jump in balls deep and go with the latest nightly/experimental
And you don't need to wipe anything before flashing the extras package.

doesn't matter,
infact if you flash yakju then you will get OTA as well. if you are in japan you can flash a japan radio on top of the rom.

Kernal?
I have been researching the many different kernels out there all day. I have been running GummyNex ROM's since I rooted my GNex. I really do like the options he has. I forget which version, but the battery life was amazing (which included the baked in kernel). I flashed to .0.9 and recently 4.0.4 1.0.1 and the battery life is like a V-12 Lamborghini. I just flashed a Franco Kernal and am hoping this fixes my battery drain issues.
Something has to give......

I'm running Liquid 1.3 and am using Franco nightly #143 and, so far, my battery life is really great. I was at 89% after 2 hours. I also want to try Milestone 3, that just came out yesterday and see how it performs.

Not possible the builds that made both of those kernels possible are different from the ground up. From video, wifi, data, etc. If your so concerned about battery life from your device why dont you buy a larger battery.

is there any other kernel that works with cm9 and supports undervolting?
maybe the Mjolnier or what he's called?
edit:
to answer your question:
because the stock kernel + stock rom has good batterie life...

best rom cm9 / cm10 / cm11? battery friendly?

Hi guys
I have this galaxy w which I had the stock rom with gingerbread.
I was searching for a custom rom for the phone and saw that there were cm9 cm10 and cm11.
I installed the new cm11 by arco68 but I'm having problems with the battery with greenify already installed.
During the night when I was asleep in 3 hours used 10% of my battery.
I'm new in roms and android development, so can anyone help me and tell me the differences between each cm version?
Any version is more lighter with the battery?
What can I do improve the battery use?
Thanks in advance

For me now the best battery saving ROM + kernel is CM 9 and hurtsky's kernel, it is just awesome, if you need battery then this is the right combination for you

Just wondering, since Kitkat is optimise for low RAM, does cm9 consume large amount of ram?

Hi, I am new to installing ROM, I have study about 3 days and decided to apply darkCM11 with khan kernel, as you mentioned,
I installed CM11 and it worked, but The device was warm and battery drained fast, I installed it again with following tuterials and format sdcard0 this time, it get better but the main problem is to install/flash another kernel or update like khan kernel or philz touch, they are failed with status 7 ,
I tried to removed assert line from updater_script but it didn't work, It seems the os is now heavier than these works and I am confused right now,
please help me :
1- what to do first, should I install CM11 from scratch ?
2- for istalling khan kernel should I install Philz touch? and if so, what I should to do with the status 7 problem
I have installed CMR 6.0.4.5 and it works,

(Q) Which Kernel?

Which kernel is best and most stable to use with stock ROM as I'm new to this device just seeing what other users opinions are that have been using it for some time.
Also does Odin have to be used for flashing is can it be done threw the standard procedure of going into recovery and flashing via install zip?
Thanks in advance

Most stable is the kernel by arco68 made for rooted stock roms.
Yes, some kernels can be flashed via CWM provided they are the correct format.

You're looking for stability so that's the most stable.
I'm personally using f4ktion's 1.3.6 but that version is currently only for AOSP roms. Sticking with Samsung stock roms you only have f4ktion's 1.3.0 to play with but some have reported that its features (BLN) are not working.

Vikinger Kernel is based on arcos modified stock kernel with the extra of bln-feature. Should be as stable as arcos. Never faced unstability and I am using it since release

Are you talking about his kernel? http://forum.xda-developers.com/showthread.php?p=47893414
Sent from my GT-I9195 using Tapatalk

yes

My favourite would be F4ktion's, and I spent the last week on it.
Unfortunately the wifi seems to be broken - works at first, but sooner or later (typically within a few hours) something happens, phone becomes hot, wifi can't be switched off, and everything becomes laggy.
Battery will last two-three hours once that happens and the phone will blame wifi for 90% of battery usage.
Only reboot fixes it, until it happens again.
During the last week I was experimenting with different solutions such as using stock's configuration files (the stuff under etc/firmware/wlan/prima) as well as trying to replace the prima kernel module from other kernels. Nothing helped.
(well, most of my attempts made wifi not work lol, the few that worked didn't fix the problem)
If anyone has any ideas what else to try, it would be great -- the kernel was great otherwise (after lowering minimal frequency down to 160-ish MHz battery prediction exceeded 6 days, and that's before I undervolted anything).
In the meantime I'm on Vikinger's kernel - not because I use its features but because installing it was the easiest way to get wifi working again,

Does Vikinger's custom kernel support performance control where you can change clock support etc?

No
No clock change beyond what stock has, no undervolting.
It doesn't have any interesting governors either.

like I said. It's just arcos kernel with the extra of bln support. you could have get that information from the first post of the vikinger kernel thread. all features are mentioned there

if you debloated and make knox-free, stock rom will have good battery life, better camera, and samsung framework features (things you lost in custom rom)
if you want to try a custom rom, i recommend you try Mokee (stable) with last Fak Kernel, mokee has an amazing saving power feature and is the more stable rom (in my opinion), with fak kernel with right settings and undervolt (see in fak thread, or pm me) you will get the best battery life, my goals are the same as yours (battery life), and i already try almost every rom here (right now iam trying LiquidSmooth, but i did not like it...will try next the S5 proyect, and wait for official 4.4.4 to test, but until now, mokee is my prefered rom
Dont know if last fak kernel is working with mokee, when a try it some time ago it give me FC, but i think last version works, cause iam using it with liquismooth right now, but even with the stock mokee kernel, it has amazing battery life.

I'am using last version, get some random reboots (i think its because of fak kernel and undervolt...) i miss some launcher options like mokee have (i know i can change launcher...) i found the rom a little confusing, the way the settings are in config options, and there are too much thinks i dont use and dont like like (side app bar, pie control...etc) .
The rom is good, its just my PERSONAL taste, i like it clean,iam a big fan of mokee, and stock rom, just go to a custom rom for 4.4.4 and better battery like i like i say, just waiting for official 4.4.4 - the quality of camera we loss in custom rom its a big point for me to go back when its released

Hi guys, first of all let me apologize up front for posting this question without knowing whether it has been answered billion times before. It's my first Samsung phone after having Motorola for a long time and the transition to the new apps and vocabulary is not that straightforward.
I've got an I-9190 running 4.2.2 from a carrier and they still haven't upgraded to 4.4. But when I entered to the website above, there's a 4.4.2 firmware for my country and my device. The upgrade seems rather easy, but I'm not sure whether it will run or not. I would really like to upgrade to 4.4.2 and I'm quite confident I'd be able to do it using Odin, but my question is if that firmware could run on my device. Any tips are welcome.
Thanks!
