(But CM has really good kernel)

When flashing a custom ROM the kernel is flashed as well. Most of the time that kernel is an adapted kernel of a widely used one (e.g. Semaphore or DerTeufel), so that it can be verified in conjunction with the ROM. So yes, when flashing the custom ROM, immediately after that flash the kernel of choice. With the right app, you can even configure the kernel and play around with strings and scripts

[Q] Updating Kernel

I was just wondering that if I am going to update my kernel is it necessary to re-install the rom or do I just install the zip with clockwork and away i go? I've searched the forum and couldn't find anything regarding it, I would appreciate the help! Thanks.
you can just use CWM to installed the kernels without installing the rom but there might be some compatibility issues, so check before doing it.
Ok because the reason I'm asking is because I have SupeAosp with the Trinity kernel but I'm thinking on either upgrading for Trinity 12 to 14 or trying out James Bond Kernel and I thought that there might be some prep work involved.

just flash the newer kernel on top. be sure its compatable with the rom. if you do have issues, just reflash the rom(that will bring you back to the roms "stock" kernel).
In this case you can test out different kernels but make sure you have the trinity kernel file in the root folder in case which ever kernel you do flash doesn't work out.
In such a case you would just boot into CWM and re-flash the morfic kernel.

Thanks for the insight, I look forward to testing out many kernels!

[Q] [i9020-T] Trinity UV Kernel Flashing

Hey everyone I'm kinda new to the whole kernel flashing business and I'm trying to flash the UV Trinity kernel to my Nexus S. From what I've read I only need to flash the zip from recovery without having to do any sort of wiping. The main problem when I tried this is that the phone went into a boot loop and wouldn't go past the boot animation for the kernel. I'm not sure if it's because the kernel is based off of 2.3.4 and I'm currently running CM-7.0.3. Morfic's thread indicated that the kernel was made for CM7 so I don't know what's going wrong here.

You have a ROM based on 2.3.3, meaning it's not compatible with a kernel made for 2.3.4.
Try flashing the latest cm7 and then the kernel.

Would it work if I tried a CM7 variant that's based off of the 2.3.4 source? I'm going for a stable phone and unsure about the nightly builds at this point. If not I'll probably just wait CM to update and release the rom.

it should work on any 2.3.4 cm based roms.

[Q] Faux123 stock ov kernal & paul's patch

hey everyone,
does anybody know if these two are compatible to work together or is it something where it's either or? i've been looking through the threads but haven't manage to find any answer for it. i appreciate any answers.
THANKS!
All reports say there is no reason for Pauls patch on custom roms.
oh alright. thanks for responding

Faux kernel is not a ROM. He is using it on that ROM - so the question was not specifically answered.
I had Paul's patch on stock kernel when I first flashed faux kernel, but don't know for sure if it is needed (ie - is the patch of the kernel or something else?).

Let me be more specific in case the OP did not get it. No, you do not need Pauls patch for custom kernels or roms. It is strictly designed for the stock rom to fix a mistake by LG.

The patch was an updated services.jar messed up by lg in the stock ROM. Do kernels also include a services.jar?
If so, then no need when kernels are flashed either, as it would be overwritten. This would be the clarification he (and I) was looking for. If not ??
Note - when I look in a whole ROM zip file - I can find it. Cannot when I open a kernel zip file.

What does that mean.so is the kernel baked into the rom: when we install faux's rom, we automatically get the kernel .

Yes - if you flash faux ROM - you get his kernel as part of it.
But the OP was about using faux (with) stock kernel on the stock froyo ROM. The stock ROM had some messed-up up stuff by LG in the (I have read) services.jar file in the stock ROM.
He asked if he could (should) use the paul patch with this combination. Since the services.jar is (I also believe) not changed by the kernel only, it appears that it should be flashed on top of the stock ROM once (unless you wipe and it is then gone), and then flash the kernel (I did that).
For ALL CM ROMs - different services.jar - no problem. But for EB and other stock based froyp ROM's - I am not sure. If the Dev's built paul's fix into the services.jar -then they are OK. If not, they might be able to use the fix also.
Would REALLY like to hear from one of the Dev's on this. Been all over the forums, and with respect to the kernel only and other than stock froyo ROM's - it has not been clearly spelled out.
its for STOCK roms not custom kernels dont matter in this pauls patch fixes a problem with lg stock rom all custom roms should have this fixed

[Q] Little help installing rom

Atm i have elementalx kernel installed and thinking about switching to franco when i install a new rom. I am on stock rom and will probably flash to Slimkat, will i just have to flash Rom + google apps and then elementalx/franco?
Read the op for slim. If it says to flash gapps then you'll need to do that. Then flash the kernel

About incorrect kernel flashing and camera bug

I have this question about kernel flashing, i tried google but no luck so xda is my last resort, anyway i want to flash a overclocked kernel of another rom, if i do so will it hard brick my device, as i cant try it not until i know that i can boot back into recovery even with incorrect kernel, i really hope someone can answer this. And oh yes i need to ask another question about camera not focusing correctly,i mean it focuses correctly then again becomes blur to take a shot, but when i do video calling in whatsapp, it works kinda ok that what my partner said but idk i have Grand 2 ms013g. Thnx

It is impossible to answer that if we don't know what kernel you're trying to flash and what specific device model number you're trying to flash it on or what ROM you're using(i.e. custom ROM or Stock ROM, if custom ROM, what ROM?)
If the kernel was not made for your device, you can't use it. If it was made for your device, then it is a question of whether the kernel is compatible with the ROM you're using.

Ummm
This is the first time that someone replied to my post on xda i m lucky ig, and thnx a lot for the precious reply, so i have aokp 7.1.2 custom rom, and i think it has stock kernel, i want to flash deds kernel, infected kernel, and some others i need to check, which are compatible with my device but not this rom, it say touchwiz, 5.x, 6.x. and my device is Samsung Grand 2 G7102 with msm8226 i want to install overclock kernel as i m more into gamings even tho i still have some good gaming but not that good those kernel support overclocking upto 1.6ghz, if u need more info i m willing to give it to u.

TouchWIz stuff is stock only, you can't mix TouchWiz stuff with custom ROMs such as AOSP, AOKP, LOS, etc.
Touchwiz can use modified stock kernels that have overclock support built in but you can't use stock kernel or modified stock kernels with custom ROMs.
Likewise, you can't use stock with custom kernels either, stock can only use stock and modified stock kernel.
