Hi
Since the CM version of Aero isn't available as a single zip, I was wondering whether somebody is using Aero Kernel from Quarx's CM11 on other AOSP custom ROMs.
Do I just need to take the boot.img or do I need other files, too? For example Phantom Kernel also has Wifi files included
Edit:
Ok, I extracted the boot.img and flashed it using Flashify, but Wifi didn't work. So there is indeed something missing

When I install a custom Rom which works with custom Kernel do I install the kernel automatically too? Or I need to manual install the kernel?
Normally the kernel is included in the ROM. If not flash it manually
The kernel will be included in the rom you flash. Whether or not its a custom or stock kernel is down to the developers preference. If the kernel included is not to your liking you can flash a different one.
Thank you!
I don't really understand roms with built in kernels. Say you flash a kernel then flash a rom with a built in kernel. Does the built in kernel replace the previously flashed kernel?
And do all roms have a built in kernel?
without kernel the ROM can't work. It is a bridge between applications and the actual data processing done at the hardware level.
- you can always have one kernel to the same time
- every ROM has a kernel included
- you can flash different kernel after flashing a ROM
See the picture here http://en.wikipedia.org/wiki/Kernel_(computing)
Ok so a built in kernel always replaces the existing one?
if you flash a Custom ROM you have the kernel which is included in the custom ROM
And after this you can flash a differnt kernel if you want
Hi all, I've searched and can't find an answer to this, I would like to be able to flash a stock kernel without having to flash a complete ROM, at the moment I've got the latest OTA from Asus which I've rooted and put CWM on - all is very stable and I'm happy with it. However I like to experiment with custom Kernels , my point is, where can i find a stock Asus kernel (blob or zip I don't mind ) that I can flash using CWM or dd etc... ? My current build is 9.2.1.24 with kernel 2.6.39.4 [email protected]#1
Many thanks

It's better to backup the whole ROM since most kernels come with their own modules and/or libraries. Backing up only kernel and restore it may cause some issues e.g. Wi-fi not working etc.
Ok, thanks for that
i am not overly familiar with many things regarding different kernels and how to work with them, so i was wishing a few questions that i had could be clarified by someone who knows:
1. when a kernel is flashed? i mean except for the times when we flash kernel.zips via recovery, is it flashed whenever we install a custom rom? or is it flashed with bootloaders when we flash firmware?
2. I am using CM12 official nightly and facing camera frizz issues. I came across a post in the official CM12 thread where they said flashing a modified kernel supposedly fixed this problem. Now my question is, after flashing a custom kernel, is there any way to go back to the stock one? by stock i mean either the one i was on right before flashing the custom kernel or stock moto g kernel provided by motorola?
that also begets the question, can kernels be backed up like roms using recovery?

1. The kernel is first flashed when you install a ROM. You are supposed to flash a custom kernel after flashing a ROM otherwise the rom zip will overwrite it. It doesn't matter if you install it in the recovery or the boot loader.
2. To go back to the stock kernel just take it from the zip of the ROM and flash in the bootloader
where can i find the kernel inside the rom zip?
and if i want the stock motorola kernel that comes with factory firmwares
how can i collect that?
A ROM.zip contains the system folder and a boot.img
The kernel is in the boot.img
So if u flash a different kernel and still facing problems then flash the ROM again.

flashing only the boot.img of a rom wont bring back the default kernel?
and is there any way to make a flashable zip of a kernel from that particualr boot.img?cause all the kernels i see (like donkey kang/customized cm12 kernel) there are all distributed in .zip format.....
So the situation currently is that I have flashed CM 13 to my Galaxy S4 Mini and I also flashed a custom kernel (from a different person) after. I am experiencing some multi-touch issues when using the antutu multitouch test. I wanted to see if it was the kernel that was causing it and if the stock kernel would fix the issue, however, to do this I need the original stock CM 13 kernel but I don't know where I can find the zip file to flash it. Can anyone help out?
Please and thanks!!
EDIT: Never mind I've figured it out. If anyone is in the same boat, simply extract the boot.img from your CM13 ROM zip file (this is the image file which contains the respective kernel) and use Flashify (requires root) to flash your stock CM13 kernel that you just extracted from your ROM zip file.
