Hello community,
I am a rookie in the subject of kernels/roms and I would love to have some precious help from any1 that knows even the smallest of information. I recently installed CM kernel and CM nightly 0422. The thing is, I read in many forums (in here as well) that there is a kernel that can boost battery life to its max, Franco Kernel. But I also read that it is somehow incompatible with CM 10+ and causes bootloop if you install it with CM already in phone. What I can't understand is why can't I just simply replace CM kernel (like stock kernel was replaced by CM kernel) by Franco Kernel? What is the fact that I am missing?
ALL (and I mean ALL) help will be highly appreaciated, thanks for your time

first off.. there is no magic pill to give your phone for battery life. battery life mostly depends on your personal usage, your personal setup, your apps used, and most importantly the quality of your phone/data connection. everything else is minor for battery life, including kernels.
cm uses CAF as its base now, they went away from aosp(like most kernels here). so everything that is aosp based is not compatible with cm anymore. franco kernel is aosp based(most kernels are). there are a few kernels that are CAF based built just for cm and cm based roms.

Thanks for your time and your answer
First of all, I know for myself that there is no magic pill about battery life, I just read in too many threads that FK added a good portion of battery life (with same use of phone like when it had CM) ! Moreover it allows you to overclock (my) Nexus5 beyond 2.2GHz, something that CM doesn't allow you too (I know that overclocking kills battery, I just want to test something). What I don't understand is how can FK mess up with CM when both are different kernels and by installing FK over CM means that FK replaces CM. There is no CM in the end, only FK. Or not...? What have I understood wrong?
Thanks again

yes, franco would replace cm kernel if all worked right. but what you are doing is replacing cm kernel with franco kernel, but cm rom stays on your phone. franco kernel is incompatible with cm rom. since franco is aosp and cm is caf, your phone would never boot up all the way.

So, if I am getting your point right, since one is aosp and the other is caf THAT is the reason why CM doesn't uninstall and will exist together with franco? Is there a way to permanently delete CM in order to install franco? Maybe to go back to stock kernel then install FK?

its not about the kernel, its about the rom. they are different things. when you flash a kernel(any), it replaces the kernel thats on your phone(kernels come with roms, cm kernel with cm rom). cm rom includes cm kernel, both are built from caf source. franco kernel is aosp, it is not compatible with cm rom. it has nothing to do with cm kernel, it replaces cm kernel when flashed. but you will never boot up your phone because it isnt compatible with cm rom.

ok, finally I got it, thanks to you Last question... is there a way to get FK now or am I just locked to caf due to CM "for life"? which way (if there is any at all) in your opinion is the best way to go from CM to FK? maybe go back to stock rom/kernel then flash FK? Will this work?

no, they arent compatible at all. you can not use franco kernel with any cm based roms. you can change roms and use franco kernel with it, any aosp rom or even the stock rom. but cm isnt compatible at all with franko kernel.

If your looking for a good CAF kernel to run with a PAC or CM based ROM. I'd recommend the ElementalX CAF kernel. It's very stable, rich features, great performance and great battery life. Make sure to read the OP for directions and if you decide to try it out download the ElementalX R38 version with the aromma installer (not the express version) As with running any new kernel run it for a few days minimum to allow for it by on settle in.
There is another option for you to explore too - http://forum.xda-developers.com/google-nexus-5/development/cm11-users-heres-how-aospnon-caf-t2626961
This allows you to run a script that will basically De-CAF your rom and allow you to run a AOSP kernel on CM11ROMs.. Be sure to read the OP. It works with many CM11 and CM based ROMs, but not on all the newest versions. Definitely worth checking out.

Thanks for your interest and time! I will sure check both your ROM and the De-CAF script soon and post my opinion/experience ! For newbies like me that are reading this post, here is a quite enbrightening thread about CAF and qualcomm processors (although it's Reddit, it's quite explanatory).
Peace!

So, do you need a specific ROM for specific kernels? Or can you download kernels without a ROM?

I know I am sounding like a total noob right now, I've flashed ROMs many times but don't know much about kernels
@jongonzalez716705
Of course you can flash a kernel without a rom.
Make sure that the kernel is compatible with your current rom.
Profits about a kernel;
+ Some kernels let your overlock your processors
+ faster boot time
+ some kernels have some other advantages.
Which phone do you have?

I currently have a Samsung Galaxy S 5 SM-G900T.

I know but I've downloaded a ROM before that had its own custom kernel. Had fun overclocking but spent more time underclocking. Is there somewhere where I can download certain kernels?
Yes,you can flash Kernels.
Why are custom kernels android useful?
Ans:Kernels are the brain of your Android device and communicate between software and hardware. Therefore, they are responsible for managing things like CPU / GPU clocking speed, screen sensitivity / colors or voltage. By using a custom kernel you can not only improve battery life, but also increase system performance.
Many custom ROMs already come with their own kernels. This is done to implement software communication of the custom ROM with the hardware of the device and also to ensure a better performance. Nevertheless, you are often also able to flash custom kernels to custom ROMs. If you decided to stick to a rooted version of stock Android, flashing a new kernel can offer you additional performance with the convenience of a stock OS.
Always make sure to check compatibility of the kernel with your ROM and device, because flashing a wrong kernel can brick your phone!
You can use this apk called as Franco.kernel. The app is available in playstore.
Yeah I was wondering this too....
Is it possible to take my original rom kernel (built for mediatek 6582) and use it on say cyanogen ?

Praise God! The AKLU kernel has arrived on the Galaxy Note Edge in the flavor of NOUGAT!
NOTE: I highly recommend turning off THERMAL CORE CONTROL! Use THERMAL TEMPERATURE THROTTLE instead. Thermal core control has been known to cause random reboots on this kernel before when gaming or during heavy use. You can use Kernel Adiutor to adjust these settings.
TBLTE AKLU KERNEL for AOKP 7.1.2!
MAY work for other LineageOS based roms, e.g., RR, PAC,AOKP, LineageOS, etc.
Download:

- Updated kernel to include kexec hardboot for MultiRom support.
20170316
-Update for OMS support.
20170217
- Fix WiFi hot spot error for Nougat.
- Overclocked the GPU from 600MHz to 633MHz
- Overclocked the CPU from 2649MHz to 2688MHz
- Added governors: Bioshock, Lionheart, Nightmare, Darkness
- Removed input boost, use cpu boost instead
- Added I/O schedulers: FIOPS, ZEN
I haven't loaded up AOKP yet but this kernel is working beautifully with RR and the data fix. You rock man.

Thanks for the thought, but I do not accept donations. I just tinker for fun, and have my own rewards. Besides, guys like @Mickey387 did all the heavy lifting, I just try to put the device trees and vendor blobs to good use, with a few edits here and there. Glad to know that my work is appreciated, though.
The slim 7 aklu kernel appears to be slightly unstable at this time. Please use with caution.
EDIT: Updated the kernel and fixed a few bugs that I missed in the first build. SHOULD be better now. Please turn off thermal core control for best performance!
Also, if you flashed superSU in Slim to root it, you need to flash the kernel, then immidiately flash superSU, then reboot.

I have noticed that many of these processors on the note4/edge are of a good bin.. Mine can run about 45mv off from stock.. Have you ever considered adding CPU Voltage control to help a bit with battery longivity?

On my MM kernels I did implement UV, but the way I did it in MM fails to pass in the N kernel. Not because it doesn't work, but rather that new build standards don't allow it. With the recent birth of my son, I have not had time yet to go back to it and figure out what was wrong yet. Are you familiar with kernel work? You could look at my github and my kernel source, perhaps you could show me where I went wrong?
If I can get passed that, I can implement the UV again. I also have the same problem for GPU voltage control, which I used to put on my MM kernels as well.
Perhaps when life slows down a bit, I can look back into it.

Oh I see, i honestly never looked at the structure of Nougat kernels. Any time I want to implement a change somebody does it better and beats me to the punch.. I will look at it just in case I see something..
On another note, these things however fun (development) not being trully important, may your family be blessed by the big guy.

You can use some 2 years old device specific builds with old OC Kernel only.
UA doesn't have a theme manager - it's almost pure AOSP and won't have any extras added in future (maybe an integrated Updater only).
