replacing rom...replace kernel too? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

i went from ktoonsez ROM to liquidsmooth ROM today and now i want to go back to ktoonsez. While I was on liquidsmooth I installed the most recent ktoonsez kernel...when I restore my ktoonsez ROM do I also have to reflash my ktoonsez kernel, or will it stay from the liquid smooth flash?
does the situation change depending on whether i factory reset or not?

When you switch ROMs, it is always advised to do a clean wipe. I believe that will clear your kernel as well, so you should reflash it. This is the best way to ensure smooth performance with minimal complications.

Most ROMs come with a kernel, flashing another kernel on top of it is not advised unless you want a certain kernel.

When flashing ROM's it will always be replaced. Each ROM has a boot.img, and that is where the kernel is stored (to my brief dev'ing knowledge). So reflash the proper kernel version appropriate for liquidsmooth and you'll be good to go. You should also back up your kernel tweaks via KTweaker so that you can just do a quick restore if you've done a lot of undervolting like a lot of us. Makes flashing ROM's a breeze.

Kernel and ROM Mix/Match

Can you just mix and match a kernel with a custom ROM? Or how do I know if they are compatible, without nandroid+trial+error.
I was using stock/rooted jellybean ROM + franco kernel. I just flashed AOKP which includes it's own kernel (tuna-faux), but want to go back to franco.
Thanks for the help. I did try searching but did not find this information.
as long as the kernel supports the android version (4.0.4 or 4.1.1, etc) of the rom you are on, you're fine.

And are they backwards compatible? Can I use a 4.1.1 kernel with a 4.0.4 ROM?
Thanks for the reply!

Trial and error I'm afraid. I had AOKP and flashed Franco on top and it broke a couple minor things, like Settings - Storage would FC every time with this combination. So I assumed there is a reason AOKP came with tuna-faux, it was tested on it and made for it.
aokp and cyanogen come with a kernel for their code, i think you can't flash other kernel

You might be on Alpha 29 or a lower version based on the timestamps on Morfic's site:
http://www.derkernel.com/ics-d2.php
I am on A43, I think A37 introduced tweaks in color, I would recommend upgrading to that atleast.
Make sure you choose the proper kernel, ICS or CM.

How would i know the proper kernel i need, ics or cm... is it if i have a cm rom than i need a cm kernel?

Yea you got it, CM roms need CM kernels, Stock roms need Stock kernels.
If you are on the Wicked Rom, it is based off the Stock Rom, so download the stock kernel:

Need help picking a ROM / kernel

I've rooted my HTC Evo 4G (not LTE). I tried to set up a swap partition and learned that i need a different kernel. Regardless of whether or not i use swap memory, I'd still like to find a good ROM/Kernel. I'd love ICS, but they all say that 4g and the camera doesn't work yet. I have trouble finding the most up to date information. Recommendations on ROMS / Kernels / combinations?

Okay, I found the kernel ... now I need to find the rom, right? because if I flash the kernel into the stock rom it will freak out ... so it's just a matter of executing two zips from recovery, the rom then the kernel? or am i forgetting something?

As long as the kernel matches the stock rom you can use it. It needs to be a git gingerbread sense kernel of you are on 2.3.3 or 2.3.5 stock if you're on 2.2 stock needs to be a froyo kernel. If you go to something like cm7 or decks reloaded, anything aosp based make sure you use an aosp gingerbread kernel. If you try ics and want a custom kernel or jb make sure to use matching kernels or you'll end up in a bootloop and need to reflash the rom to fix the kernel
Edit: when flashing make sure to do the proper wipes. For a rom wipe everything but the SD card, for a kernel or a modification wipe only cache and dalvik cache. When flashing a rom and a kernel at the same time, wipe everything but SD for rom then wipe.cache and dalvik and flash the kernel

Yes cm7.2 is a rom, I always used tiamat 4.1.0 on cm7.2. The kernel will add different governors, clockspeeds for overclocking, change the scheduler and allow for undervolting. The kernel is what allows the rom to talk to the hardware and vice versa, it contains all of the drivers for the hardware.

I've searched the kernal's original thread and found people giving a solution of "clear caches" Well I've been there done that.
I've let the black screen stand for about 15min hoping it was just loading the new kernal slowly, but its stuck for sure.
I've tried clearing cache's before and after the flash with no success.

Your ROM could be using a base that is before 10/14 making the newest KT incompatible try flashing aosp jb kernel before 10/14 after doing Full Wipe. If not working still your ROM maybe incompatible all together.

Crap I'll pm him a link to mine. I thought he had one already or I would have passed it along a while ago.
Yep make sure the version of the kernel is compatible with your rom.
I flashed a PA rom and the kernel agrees with that so thanks for the input. It wasn't compatible after all.

Glad to see you figured it out. Some phones will not accept KT kernel whatsoever as reported in his thread. So consider ourselves the lucky few able to flash it

[Q] AOKP kernel help please

Just a quick question because im not familiar with terms used.
i installed Official AOKP JB M1 on my ATT S3
will this kernel work with it or brick my phone?
AOSP JELLYBEAN: Download CWM flashable zip kernel
i dont know when to use the touchwiz jb or aosp jb version please help
Not to sure about the question here. Is that the ROM you flashed? Or the kernel? You always have the potential of bricking your phone flashing anything to it. I know this from experience!! Make a nandroid backup through recovery an flash what you want. I am currently using AOKP by task650 and ktoonsez, accompanied by the KT747 kernel. Cant go wrong with that setup!!! Hope this helped.
Same as above, don't really know what you're asking. If you are wanting to install the KT747 Kernel (by the sounds of it), then you would need to install the AOSP version after installing the rom (flash in recovery). Sorry I can't help you much, didn't really understand the question.
I highly suggest you do a little research before flashing anything else to your device. If you don't know what something is or does, don't flash it until you do. You dont need it. Unless you would like to brick your device.

Just for your information aokp(android open kang project) uses the same kernel as aosp(android open source project). If you are unsure about flashing kernels then by all means don't flash it until you do a little research about it, usually when installing a new kernel you should...
1install ROM from clean wipe(wipe caches,system)
2install kernel
3wipe caches, davlik cache, and fix permissions after you install kernel.
You should be fine after following these instructions.
Now if you plan on tweaker your systems performance via ktweaker read this before as it explains undervolting and the effects it has on your phone.
