i got a rooted phone. how do i remove a kernel from my phone without flashing another rom?
Flash another kernel.
why do you remove kernel??
if you remove it must be brick.
You mean "change" kernel??

well, i want to install the unity v9 kernel on my rooted phone running virtuous unity. in case something goes wrong with this kernel, i want to be able to remove it. but since you say you can only change it, how can i revert back (or change) to the kernel i had previously on my rom?
Make a nandroid backup so if you want to revert to your previous setup just restore the backup. You could also download the original kernel that came with your rom so you can flash back.

What are you wanting to adjust? The only way to adjust a kernel is ti do it when its compiled from source code.
You cant remove a Kernel. You can ONLY change it.
Make a nandroid backup of your current kernel and flash a new kernel.If anything goes wrong just revert it.

If i remove my kernel how work my arc s ?
Flashing the rom over itself (without wiping data) will keep your user apps intact and restore the kernel that came with the rom.
In the future it's a good idea to do a backup any time you flash a new rom or kernel. You can always delete old backups to save space.

If you're talking about overclocking, undervolting, governors, etc. read the Unity v9 Kernel thread. I also recommend reading droidphile's excellent cpu tweaking faq/tutorial:

Take the ROM you originally downloaded and use 7zip to extract the contents. Inside here you should find the kernel (boot.img) but not always in .img format so if you don't see it let me know.
Then use fastboot to flash this kernel to your phone, more info on that here

cant i flash that PA kernel in CWM recovery?
Sure if there is a recovery flashable .zip out there, you'll have to search for one or create your own. If you search my other threads i have one on creating flashable .zips but it will be more work than just flashing in fastboot.
Let me know if you need a hand either way

It depends on your phone model. Because you mentioned flashtool I'm assuming you have an Xperia device. You can't flash kernels from cwm.

The post above answered your question and the answer is NO.
OK and thanks.
Thank you very much for the information
Hello everybody,
Please bear with me a little and if you would like to answer, please give as much details as possible.
I have and Xperia Acro S, with unlocked boot loader running a custom rom with stock kernel 4.0.4, and I have root access, and CWM installed.
I am trying to install a cyanogen based rom, with a custom kernel obviously.
I have downloaded a zip file which contains a boot.img file.
The developer asked to flash the boot.img using flashtool first, then to flash the rom with cwm. And here's my question(s)
As I understood, this boot.img contains the kernel, do I need to use flashtool if I already have CWM installed, or would CWM install the kernel also?
And let's say i extracted the boot.img from the zip file and flashed it, wouldn't this remove CWM from the phone?
And then, should the boot.img stay inside the zip file while flashing it with CWM later? or should i remove it because CWM can't flash boot.img?
I have successfully installed cyanogen roms on nexus s, with CWM alone, and the phone booted normally, and I suppose it replaced the kernel correctly, or it didn't?
And please if you could explain what exactly this boot.img is, and how is it different from a normal kernel file inside the zip, does it also contain a recovery? you get my point.
Thanks for reading so far, and thanks in advance for any answers.
i have xperia tipo and when i go to flash vengeance kernel with flashtool says:you need to be root and e.g.
i have unlocked bootloader and rooted phone!!!!!!!!please help me!!!!!!!!!!!!!(sorry for my bad english)

Oh no no. You are going the Samsung way I guess. In all Sony phones, we dont have a recovery partition. That means that we can't flash kernels from CWM. The only way is fastboot. So no way to include kernel in your rom zip file. Sorry. At the most you can only recommend users to use a particular kernel.

OHHHH!!... but in the tutorial by nero young on how to build a custom rom .. he has a sk17i and he uses his own custom kernel when he builds the rom... http://forum.xda-developers.com/showthread.php?p=26283930
so if i cant use a custom kernel .. how do i extract the kernel.sin into the rom?
Basically you just can't flash kernel with the phone.
Usual practive in our phones is to include th boot.img in the rom file and ask it to be extracted and flashed via fastboot through pc.
Hope it helps
Don't know about the tuto

You don't have to worry about the kernel when building a rom on stock rom. Just work on the system and you should have a proper working rom.

Yes. Kitchen requires a kernel for the working folder. Btw why do you need kitchen? If you need any help for developing your rom, just pm me.

Dude you can directly add root and busybox.and whatever you want. Check your pm.

Hi,
You can use the attached META-INF folder. It has only the basic stuff like basic symlinks and permissions required for the rom to work properly. Just check the comments in the updater-script to know where to add your tweaks.
Good luck developing

How do I extract a kernel from one rom to another rom?
I did do a search and from what I have read you can download both zips and extract the boot.img from one rom and put it in the other rom. Is this correct, a step by step on PC or phone would be nice. Or just extract boot.img from one rom then install the other rom and flash the other boot.img in TWRP on top of that rom. Again a step by step guide would help me. If I could get the source is there a easy way to make a flashable zip? Or if there is another method.
EDIT: I'm S-Off and 3.16 without touchpanel and trying to take one CM10 kernel from a rom and place it in another CM10 rom then flash.

Have you tried this? : https://play.google.com/store/apps/details?id=com.joeykrim.flashimagegui
Are you s-on?
If so, after extracting boot.img got to your folder that has your fastboot and adb exes in cmd and put your phone in fastboot usb and place your boot.img then issue the command: fastboot flash boot boot.img
Good luck!

If you are s-off you can use the same commands or flash custom kernels, depending on the rom version you are using you just need to place the zip in your sd card and flash through twrp... Can you give more details of your setup and what kernel rom are u using or which one are you trying /want to flash?
For 3.16 you can use either thicklizard's Arc Reactor Kernel or flas2's Bulletproof... And depending on the rom you are running overclock/underclock - change schedulers or change voltage values using scripts or apps like setcpu, android tuner, etc...

I just gave up for the time the being tried all the CM10/AOSP roms on here and Evervolv kernel/rom is only rom that bluetooth on my vehicle like the Sense roms I used. I tried to use Flash Image GUI and it extracted the kernel I think but it put ChameleonOS on boot animation and would not load. Then I took the boot.img out of the Evervolv rom and replace it in the ChameleonOS and flashed and it would not load so it is either not compatible or I am doing something wrong.
Sounds like they aren't compatible.

You have to flash the kernel (boot.img) before a custom rom will run. Extract the boot.img from the rom then flash it via fastboot. Then go back to recovery and flash the rom.
