And I c on other forums tlking about kernels?
Is it nessasry to install one?
And what do they do?..
Sorry if I'm a noob. Just recently got my g2

You don't need to install a kernel because you already have one its included on all roms otherwise you wouldn't be able to use your phone. kernel is basically a leyer between hardware and your os .you can try different ones if you wanna oc or get a better battery life or wifi calling and so on .and you must make sure its compatible with your rom. also may I suggest you search for kernel in Wikipedia if you wanna get a better understanding of what is kernel and what it does.

Hi all,
I am here to share another [How to] on flashing a kernel. There are quite a number of kernel available in our forum such as Cow Kernel, stock kernel, etc. They have different capability such as UV, OC and equipped with different governors too.
This tutorial will teach u how to flash a kernel easily.
HOW?
To flash a new kernel,
via adb shell
1) Download the kernel
It is as easy as just copy the boot.img from the ROM equipped with kernel u want.
2) Download the Wifi module dhd.ko
Copy dhd.ko from the ROM with kernel u want, it is under /system/etc/wifi
(without getting this, ur WIFI will not work)
3) Copy both files into your phone by using adb shell or simply copy them over from ur PC.
Code:
adb push boot.img /sdcard/download/
adb push dhd.ko /sdcard/download/
4) Flash to your phone
Code:
adb shell
su
dd if=/sdcard/download/boot.img of=/dev/block/mmcblk0p8
5) Copy dhd.ko to /system/etc/wifi/ via Root Explorer.
Reboot. DONE~
via CWM
1) Download the kernel u want from attachments.
2) Boot into recovery mode by pressing power+select+volume up bottons
3) Flash the zip and then Reboot
Just a personal experience, the XXLM8 and DXLM3 kernel give us better visual performance and make ur Temple Run smoother.
Same advice, do at ur own risk. Remember to do a nandroid backup beforehand.
Thanks bro...
How about battery life? Which one is better, Cow's or XXLM8 kernel?
in my opinion Cow kernel is the most performant, best benchmark scores and best ram management. XXLM8 has a better battery life and a good durability.
I personally prefer the Cow one couse of the performance.
In my opinion cow rom are best with benchmark point which is very high but not in real app performance..
I tested temple run on both rom, and xxlm8 just slightly faster than cow
And also battery life is longer with xxlm8..

Terifish is correct. Cow kernel has better benchmark score but that is not true in real application. Overclocking doesn't improve the performance for gaming because that is actually related to GPU and ram management.
XXLM8 has been proven to have better gaming performance. U can personally experience it when playing Temple Run.

Theoretically, cow's kernel should give better battery life as it is undervolted.

U need to use adb shell for flashing it. Not sure whether a flashable zip can be created for this. Any expert can help on this?

And this one too cuz when I using Cow rom a while ago , I put on standby it consume 1% for 4 hours , under normal use (wifi all day long, some call, sms, email , gaming ) still can hold more than 50 hours . . but change to others roms due to FC essue..

LOL~ Seems like XXLM8 is really a good kernel for our SGW at this moment.

really agree with you..
i'm very satisfied with my SGW battery performance with XXLM8
Which governor should be adjusted to save power and still have a good performance on XXLM8?

I suggest using CPU profile scheduler such as SetCPU. Use ondemand for normal usage and set powersave for screen off.

I wonder that too... I'm not familiar with adb yet... CWM rules when it comes down to being "easy", hence safe, if you know what I mean...
I'm really excited to flash this kernel now...
I noticed that inside the nandroid backup folder there is a "boot.img", so, why can't we just exchange it by the one from XXLM8 and just restore it to have it flashed? I didn't do it yet because there is no turning back after messing with the boot.img...
I read this thread, but I'm still not confident enough to do it...
Does anyone know if my theory stands?

No. U can't do that. If u replace the boot.img in a ROM zip, there will be md5 checksum mismatch error. U need to resign the zip again.
okay, if you want to try different kernels without using adb, attached are update zip for Cow kernel and XXLM8 kernel...
just put it on your sdcard, and install it through CWM recovery...
enjoy...
Hello to all, i want to flash the xxlm8 zip using cwm. But as mentioned do i still need to flash the wifi module? or is it already included in the zip file? not comfortable with adb as i might mess things up.

the specific wifi module for each kernel is already included in each update zip file... i tested both of the zip files, and i can switch kernel whenever i want...

Hi, each time I installed any stock based rom my phone wont detect/connect to any wifi network.But the weird thing is, if I leave the wifi on and restart my phone, it connects with the wifi network, however when I turn it off and on again, the issue arises. I had tried :
Rom: Ultimate hd, sparta charge, xperia t rom, miui v4
Kernel: ktg 1.52, lupus v8, rush v6
I had never had this problem with jb roms. Please if anybody know the solution, share it with me.Thanks
Make sure you are using the right kernels and installed the right modules in CWM...

So my Question ,would anyone be so Kind to mirror the doomkernelv22.img file?
It would be very nicee
doomkernel v22 + wifi module

can't believe that even Doomlord himself didn't keep his work...

Did anybody have any 3G/network problems using doomkernel v22. As for me,I had some problems enabling 3G, and sometimes when I reboot the phone, network can not be found - but I am not sure, if this is kernel related?

Strange. I changed to Lupus kernel, data seems ok, when I reboot phone, network is there everytime. But, it is not as smooth as doomkernel. I do get some lag in homescreen, menu. I'll have to try Advanced Stock Kernel then (for Increase Internal Memory script), I hope it will work with that script.

Funny…because I do get a noticeable lag in launcher, and menus, in comparison with DK at same CPU settings
Hello there i'm using CM11 and i want to flash a better kernel to boost battery life... plz suggest me a good kernel... is there any kernel which supports Double tap to wake feature like LG G2???
There is no 'best' or 'worst' kernel at all. Kernel (and ROM for that matter) performance depends on how you use your device. A kernel what performs really well on your device may perform really poorly on another and visa versa.
The only way to find the best for your device is to flash them and test them yourself.

There is currently no custom kernels for cm 11... Only stock 4.1.2 or 4.2.2.
