A lot of times i see people say that they flasha different kernel on a custom rom.
I just download a nighlty and go from there, but people say they use that same rom with a different kernel.
How do i do this?

The same way you flash ROMs. You download them and install through recovery.

So I've been flashing various roms, kernels, and radios onto my Nexus S since the release. I've never read to deeply into the exact procedure for flashing these items.
I know you are suppose to wipe device, cache, davik, ect. But then are you suppose to flash the rom, reboot the device, and then flash the kernel and radio?
What if you wiped the device and just flashed a rom without a kernel? Does the kernel you have previously take into effect or is it built into the rom?
No, Roms come with a kernel. If you don't flash a kernel you will have whatever kernel the developer uses in his/her Rom.

Wha? Not all ROM's come with kernels... if you flash one that does not have a kernel then you will be left with what you had before (stock).
I just learned about the kernels for the XL and was interested in having the s2w feature. Can anyone advise the most stable build I can use with stable CM10 on the phone? I am new to kernel flashing and in a few threads, it appears the kernels are either CM10 nightly enabled (past the stable -- incompatible) or for Sense ROMs (also incompatible).
the kernels in the android development are sense only. since you want sleep2wake the only real option for you is rohan's kernel, its meant for aosp roms like cm10, and is the only kernel for jb roms that has s2w.
And for future references, if I am running on Rohan's kernel and flash a Sense ROM over it what would happen? Are you suppose to flash the kernel with a Sense kernel before going back to a Sense rom?

Yes, non sense kernels will not work with sense roms. Reinstall stock or one of the other sense kernels when you switch roms.

I should be more clear. If I had Rohan on my phone and went to a Sense ROM before flashing a Sense kernel, would I brick my device or would the kernel just 'not work/disable itself'?

You would just soft brick and the phone would be stuck in boot loop. Why would you even try?

So if you are on CM10, how would you flash the Sense kernel and a Sense ROM? What would the order be?

First make a full wipe (factory reset, all that), then flash your rom using the typical procedures, then flash a sense kernel. Same goes for AOSP, make a full wipe if coming from another rom, flash the rom, then the kernel.

No this could be wrong. I am assuming OP is on 1.14 hboot. Older hboots allow you to flash kernels. With 1.14, kernels will not flash in recovery. Either use fastboot to flash kernels or use flash image GUI app found in the themes and apps section. After kernel is flashed then flash your ROM in recovery as normal.

Thanks folks. Just what I needed to know for future references.
What the other guy said is true, but that was actually what I was hinting at when I said "typical procedure." I'll be more specific next time... Also, your very welcome!

in this process, when should you do the full wipe? before or after flashing the new kernel using the fastboot method?
Guys i have two question..Whats the difference between All other ROMs and Custom IO control (CM tweak)
links from https://docs.google.com/spreadsheet/ccc?key=0AntDDKv-lS6IdEt6NWVkX01vNmpfbEh4MHo4eDRCbXc#gid=0
And the second one is to flash the kernel i must first flash kernel and then the rom or first the rom and then the kernel??Thnx
Cm tweak is for cm based ROMs, all others is for, well, all others. Flash kernel after flashing ROM.

How i will find which roms are CM based?
Read the thread about the ROM you are interested in. If I'm not familiar with a ROM, i generally read the first page and the last few pages. That way I see what the dev says about it, and see more recent reviews/comments about the current version

U can go to setting-->about rom and read the information of your rom
Sup, so I'm still quite the noob at all the rooted stuff, like flashing etc... I have franco kernel and im running cm, when i update my kernel am I supposed to flash the kernel again or will it actually be updated?
For which phone n its not necessary to flash again n again unless u flash with custom rom

(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

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
