Flashing new Kernel - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I need a small clarification regarding flashing custom Kernels. (I've never flashed Kernel's separately before.)
Do I need to do some kernel cleanup before flashing a new kernel (to avoid errors)? Or is it something optional?
I found this on XDA. Is there a newer version which supports Jelly Bean?
Thanks

Best thing is to refer to the install instructions per kernel. Every AT&T SGS3 kernel I know of has them on the first post in the thread.

Any kernel with any ROM?

Forgive me if this is a newb question, but I've searched the forum a few different ways and couldn't find a real answer.
Can I use any kernel with any ROM, or should I only use the kernel (if any), associated with that ROM?
If I download and flash the CM6 Nightlies, do they come with the kernel built in?

Every rom has it own kernel, but you can flash another one if you want

not all kernels are compatible with all roms.
All roms should come with there own kernel however if you choose to select a different kernel make sure it is for the correct version of the rom (ie 2.1 vs 2.2) also some roms have other needs and you may see a separate version for them (ie netarchys has always had a separate damagecontrol kernel). If it matches versions (2.2 to 2.2) and you dont see a note on the page about a certain rom you are probably ok just nandroid before installing jsut in case.

[Q] [kernel] high on android kernel question

I'm looking for or wondering if High on Android is planning on releasing their kernel for t999uvlj4. I would've posted on the dev thread, but I don't have the proper privileges yet. I was just got so used to the little simple features that it offered for so long that I forgot it was a custom kernel and made the mistake of updating to the latest ota.
Or any other stock kernel that at least supports custom boot animations.
I don't think that kernel has been updated in ages. AFAIK all kernels support custom boot animations you just have to change it yourself.
Sent from my SGH-T999
On the SGS3 the .qmg format is used for boot animation, AFIK nobody has found a way to encode a file into .qmg, so the only way we are able to have our custom boot animation is to install a custom kernel.. High on Android has been releasing updates on the kernel for the different versions of baseband that have been released for the T999, well, at least UVALEM and UVALH2. I'm hoping that there was no kernel change in this latest OTA and I can just reinstall the High on Android UVALH2 kernel, but I don't want to find out the hard way.
I just noticed my last post put me over the top so I can post in the dev section now. I asked my question on the High on Android kernel thread, so I should get the answer I'm looking for from the dev himself.

Flashable kernel zips

I've been looking around and can't seem to find any. I wanted to try to use Hashcode's kernel with the SGT7 ROM but I don't see any way that would be possible.
You need a custom recovery first. I'd advise you to read the FAQ sticky listed in this forum, it should help get you started. And whenever you're ready to download that rom, the links to the zips are in the development thread associated with the ROM you'd want to flash.
I think they already have one. Fortunately the SGT7 rom uses hashcode's kernel. Unfortunately, you are talking about the 3.4.y, that is highly experimental and Hash only wants the more experienced people to mess with it, so as of now there is no flashable kernel for 3.4.y. If you are talking about the current 3.0 kernel then im also afraid you are out of luck on that too. There isnt one.

kernel for paranoid 3.99 for n7000

hey guys..new to this website nd flashin new roms.. currently using paranoid 3.99 for my n7000..just wanted to know what kernel should i use with this ROM for a better performance..?? and how to flash the same..sorry for the noob question bt seriously new to these stuff..
thnk yu..
Kernel choice is up to the user... any AOSP based kernel for your device will work with the ROM. You can make a decision by searching the various kernel threads in your device forum, they should also contain information on flashing. In general you flash the kernel via recovery the same way you flash a ROM (kernels must be flashed after flashing a ROM however, else the ROM will overwrite the custom kernel with it's own).

[Q] please help

Hello all. First I want to thank everyone for still being around to help, especially on such an old device.
Anyway, I recently bought one of these and got it rooted via odin. Currently that's all I've done to her. I have been looking over this forum, android forums, and Google in general prior to posting, I want to solve problems on my own, but when I can't, I'm not scared to ask for help. And I need help with a few issues. I will seperate them, to make answering them easier.
1) is twrp not available for this model?
2) if not, the only other recoverys I can find is Phils TouchWiz, and ClockworkMod recovery touch 5.8.1.5. I wouldn't think these are the same, which is suggested? Also Phils Touchwiz was last updated (that I can find) to 4.1.2 which is where I currently am, am I want to go to 4.4
3) I only see 2 ROMs listed on here, and 1 is one of the ones I was thinking of using in Dirty Unicorns. The other I was thinking about was CyanogenMod. Which of these two is suggested?
4) I have no service on this phone, as its my tinkering device. The only thing I need to work is WiFi. That being said, do I need to flash a new modem?
Do I need to flash a new kernel?
Thanks for any help you can throw me. I know there are lots of tuts for all these questions, but frankly they are all very old, and this stuff changes by the day...
1. Yes but this device has recovery and kernel built in together, this recovery is only for flashing / wiping, other than that, it is not usable with other custom roms unless the devs build it to use that
recovery along with the kernel.
2. It's the same as question 1, For Touchwiz Jellybean, you'll need a recovery kernel that supports the android version and firmware, otherwise it wouldn't work or boot up, Agat's Source GB27 for GB27 Touchwiz ROMs. Or specific AOSP Kernels for certain kernel build updates ( versions are compatible with the build date of the ROM's Original Kernel, meaning it only works on certain ROMs that are updated with the same kernel build, for example, A custom 0.0.25 will not work with stock 0.0.26 because there was a major update change in the kernel that'll make 0.0.25 not usable on it. If you use a kernel based on a specific date on an AOSP ROM that frequently updates the kernel, it may not boot up. )
3. The AOSP ROMs that are being updated at the moment are the Teams that do Nightlies. So Cyanogenmod is the only AOSP ROM that's being updated weekly for this device, I have not checked on the other ones.
4. No need to flash a modem if you don't have data service, however it may help either way when using WiFi due to dropped connections, stability etc. For AOSP, use any ICS modem, for Touchwiz, use the same android firmware modem.
Flashing a new kernel is not needed unless you don't like how the stock kernel performs whether if it's power saving or performance. AOSP kernels are kind of limited as the ones out now work with different build dates of the ROMs, Touchwiz has a couple, but Agat63's Source Kernel is recommended by everyone for GB27.
