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!

Whenever I try and flash Franco R32 to any recent CM11 nightlies or M3, I brick the phone. It boots and sits with the Google logo on the screen. I heard a rumor CM broke compatibility with Franco. Can we expect an update from Franco? it's been awhile since we have seen an updated kernal. Suggested Roms or Kernels to use?

Is Mahdi-Rom AOSP or CM (CAF) based?
I've been researching of this for the whole night last night but keep on finding mixed answer.
and now I'm hoping for you guys to answer me...i wanted to install elemental x but don't know which version to install aosp or cm
and will franco kernel be comparable since its for aosp?
Thanks soooo much to who ever answer this...!

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

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

Franco Kernel on OPO?
Any update on whether Franco Kernel is compatible with this CM based Mahdi rom on the OnePlus One?
How is it going bro's and my name is Pewdiepie
Ok I am Using Cyanogenmod latest nightly I think on my Tab 2 gt - p3100 .
I want to ask should any kernel
I mean many are saying it will fix the battery drain:laugh:
But is it recommended for advanced users or only Developers
And which kernel you think is the best for battery and compatible with CM11
Please help me:highfive:
Peace and please don't hate
No you didn't have to.
I think,stock cm kernel 3.0.31 pretty much has good battery life.
Upstream kernel changes to 3.0.101 did causes battery drain and tried to resolve by devs.
However 3.0.101 have bigger free ram next 818mb, dhollmen 820mb, however agni kernel has same with stock cm kernel.
All those custom kernel offers some features which stock kernel didn't have.
Slightly different with android-andi kernel which purpose to find kernel battery drain for 3.0.101.

Hello guys,
I'm new to Nexus 5 as well.
I have been using Chroma for few months now/
http://forum.xda-developers.com/google-nexus-5/development/rom-chroma-03-31-2015-layers-t3069105
The version I installed on mine is: 8-10-2015 built.
I have been following the post lately,
many people said, 'franco.Kernel' is a good Kernel.
how do I check if I already have franco kernel installed?
I went to About page, it says: 3.4.0-gbebb36b [email protected]#1
also,
if I want to go with franco kernel, what advantages will i get?
do i just need to download this app thru google play to install the franco kernel?

That is stock kernel. Recommend using blu_spark (aka code_blue) over franco.kernel. I won't say FK is abandoned, and it is a good kernel, but it's just not updated for the N5 much anymore. Same thing happened to the N7 2013. When the devs move on, you should also.
What do you get with a custom kernel? They say battery, performance, etc. Most of it is negligible at best. You'll need to read the kernel OPs.

Better battery life? Negligible.
New features like color control, governors (highest impact on battery life), S2W, DT2W, USB fast charge... It varies for each kernel.

I suggest you to read (again & again) the kernel threads on XDA before flashing anything. Franco is a well known kernel but we have other awesome kernels.
so my nexus 5 is stuck on the bootloop or the chroma logo...
I flashed:
1) chroma_hammerhead-ota-2015-10-05.zip
2) tk_gapps-modular-nano-5.1.1-20150927-signed.zip
then the nexus 5 was able to boot fine, and I saw the phone already has SuperSU came with the Chroma ROM
3) I went ahead download the BusyBox, and installed
4) reboot to recovery , and flashed blu_spark_r30-6.0_hammerhead_40fbe53.zip
my phone is not stuck on the ChromaLogo .....
I have also tried,, on the step 3, I flashed without installing Busybox.. It's a no go either..
any help would be appreciated..
Thanks

Here is your mistake: blu_spark_r30-6.0_hammerhead_40fbe53.zip
This kernel version is for Marshmallow.
when i was using lollipop i always went with ak kernel but since ak kernel stopped supporting oneplus one when marshmallow roms began to come i became a bit confused as to which kernel i should use.
so i did a bit of searching with kernels that existed. and the kernels i found that i could use was
1. Sultan
2. Tyr Kernel
3. Andy Kernel
4. Radioactive Kernel
so i was wondering what kernel is the best alternative to ak kernel and if so does that kernel have any problems which makes so i should avoid it?
p.s im open to discussions and even having an idea of what i should do will probly help more then it hurts

It's pretty simple actually CAF kernels usually stated in the title of the kernel thread work on CAF ROMs e.g. Sultan, and any ROM that states CAF in its title works with these kernels.
CM kernel such as Lightning, Boeffla and Andy all state specifically CM12/13 in the thread title and those work with stock CM and ROMs derived from CM source and kernel trees.
Finally Omni based kernels only one works properly (Donkey Kernel) also states Omni in the thread title.
The common denominator is that they all clearly state in the thread title what they are for so there's nothing to discuss on which ones to be used for which ROM. In regards to quality that's a bit trickier as we all like different things in a kernel and personally I'm a big fan of Boeffla when I'm on CM13 cause it works great and the app is very intuitive. I've also tried Andy kernel and its got a good mix of features. I'm on Omni 5.1.1 nightlies so I'm on the stock kernel but when I move back to Marshmallow I can update on kernels

which kernels works with which rom i already knew but i still respect the answer i got. well the main concern i had was about the quality of the roms and which roms is good for what.
It depends on what you want. For example some devs here around merge a bunch of patches to improve sth. Sometimes i dont know what they are doing. I also started with that but soon i have learned less is more. Than there are kernels with gazillion oft features to choose. Thousond hotplugs and governors etc. Than there are small and simple kernels without such experimental features close to stock. I for example dont want to tune 5 days to improve me results i like it simple. So you have 3 or more different types to choose.
1. experimental maybe unstable kernels with lots of patches
2. kernels with lots of features
3. small and simple and more stable kernel close to stock
There is no best or better kernel. Choose the one you like best.
Its your choice.
You also missed the CAF lightning Kernel built off of AK's caf kernel. It's the best kernel for CAF right now IMO. It's basically all of AK kernel's great features just updated to support CAF marshmallow and bug fixes/ latest commits. Works with synapse and all of the original AK CAF kernel profiles.
