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!

Mahdi Rom
Do I need to add the kernel off the op page or just use the one I already have in twrp, it is the Franco kernel r4. It is the same one that is on op page I think. I see some people talking about dr87 twrp. I just have the stock 2.7.1.0 twrp installed. Do I need the dr87 twrp? Sorry for the noob questions just trying to it get right. Thanks

It doesn't matter what recovery you have prior to flashing, flashing dr87 twrp will override whatever recovery you were using before. Fastboot flash it or use the flashable zip to flash it. Up to you.

MAHDI ROM
I flashed the dr87 Franco kernel today and never got past the one+ screen on boot up. I was just wondering if I needed to flash Mahdi rom first and then flash the dr87 Franco kernel? I did get the dr87 twrp installed and all is well with that. I re- flashed the Franco kernel r4 and I'm still on the stock cm rom and everything is good. After reading the MAHDI ROM forum it seems they are having problems with this.

Simply follow the steps in the MAHDI OP post.
Its pretty much.
1. Factory Wipe
2. Flash MAHDI then gapps or kernel (doesnt matter if u flash gapps or kernel first).

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

Hello guys,
I'm new to Nexus 5 as well.
I have been using Chroma for few months now/

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.

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
