[Q] change from CM11 to FRANCO KERNEL

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!

Its AOSP with CAF stuff in it. Just flash one and if it doesn't boot reflash the ROM and flash the other.

Thanks

Make a backup, flash. If it doesn't boot then it isn't compatible.

make a backup in recovery and just flash the darn kernel. if its not compatible, it wont boot. then you can either flash a known booting kernel or restore the backup you made in recovery. that's the quickest way to find your answer.

Haha this really is a good question though. I myself didn't know either. I had been under the impression it was full AOSP.
Last time I ran Franco kernel on it though all was fine.

Quite a few ROMs say AOSP but have CAF parts lol. Rarely are ROMs full CAF though, the only one that I know of is CM of course. Some AOSP kernels work with hybrids and some only do after modification.
An AOSP Dalvik will only boot up on full AOSP ROMs so it the Z2 Dalvik boots, it's full AOSP. If a CAF Dalvik boots, it's either hybrid or full. Nice way to tell

Ah thanks. I never really messed with the custom dalvik because I didn't see anything other benchmark gains.

Some people say general usage is slightly better, some say it doesn't help in general ui. Experience varies. Lol.

I ran mahdi rom for a long time use aosp kernel caf will not boot

Franco Kernel on OPO?
Any update on whether Franco Kernel is compatible with this CM based Mahdi rom on the OnePlus One?

How i can make my nexus caf ?

can i convert aosp kernal to caf ? and how ?​

Flash a CM based rom. CM is caf.
You can't run a caf kernel on an aosp or stock based rom.... As far as I know.
There's custom kernels for aosp or caf... But again, you need the correct kernel for the rom you're using.

Build the ROM/kernel from CAF repositories or cherry-pick a whole lot of CAF commits from them.

Can't help there. Never heard of that. No longer own an N5.
Did you look through or search the cm12 thread for similar issues?

Kernel for Exodus

Which kernels is there for Exodus? It's AOSP but it doesnt have sultans caf kernel so I'm not sure which to look for? cm13 or caf? or is there none that work?

Stock

......I wouldnt ask if I wanted stock. Phone gets too hot with normal use and there isn't many tweaks I can make to make it cooler.

The kernel is cm based.
Btw. there is no aosp kernel for the oneplus one. We have 4 different types. Based on CM; based on Sultans CAF kernel; based on omnirom; based on Color OS.

Lightning Kernel v22 (updated to 23 now) and Lightning kernel based on Linux kernel v3 works for me with exodus. Personally prefer the latter. Boeffla didnt boot for me with exodus and i didnt try any caf kernels.
If you have heating issues you may want to try the 6th June build if you arent using it already

Heat issue does exist in build may 23 - june 1.. Even if you change the kernel.
Check your current build.. Update to the latest one

AOSP vs MIUI

Quick question, can you install AOSP Kernel to MIUI Stock ROM?

Some kernels like DPA are compatible with both MIUI and AOSP

Generally, no, you can't -- unless otherwise stated by developer or tested by a significant number of users.
