[Q] Does a custom Rom come with a Kernel?

Does a custom Rom come with a Kernel?
My specific case :
Nexus 7 32Gb Wifi
Android 4.1.2
Rom : PA 2.54
Kernel : Franco 3.1.10
My plan is to update to PA 2.99Beta6 which is based on Android 4.2.
I'd like to know if I'll also need to flash a new kernel as part of the upgrade process or if the PA 2.99Rom also includes the required kernel.
My guess is that it will be included with the Rom but figured it wouldn't do any harm to ask.

PMSL, how on earth do you think a ROM would actually work otherwise without a kernel.
Sorry but.... #facepalm

My fear was that a Rom might use or expect the stock kernel, cheers for the answer though.
With that in mind, I wonder why Roms don't tend to ship with custom kernels. Franco's seems to be widely preferred to stock.

most roms that are actually developed ship with custom kernels(like cm for example). roms that are just compiled from aosp source that have some mods added usually use the default android kernel(or stock roms with added mods). also, many roms ship with other custom kernels included. anyways, many others prefer trinity kernel

Sorry I may have picked up on your question wrong, but many developers, well in fact most would use custom kernels, some prefer stock, stock kernels are generally very stable but quite limited in what they can do, for example take the pretty amazing Siyah on Galaxy S3 which gives you the ability to dual boot different ROM, s, i had AOSP as my main ROM and a Samsung ROM as my secondary ROM which was great for a while but they novelty wore off for me as I really only used the AOSP ROM, not to mention over clocking , etc, etc, etc.
I use Trinity Seven kernel on the Nexus and i find that the tablet seems to charge faster than with the CM kernel that comes with Liquid Smooth ROM.
Hope that answers some of your questions anyway

Closet to Original Rom?

Hi, I have been looking for a Custom Rom with a Custom Karnel that has a closest look to the original rom. Does any one has any opinions??
tnx

I would recommend the following, because of my experience with them.
1. SaberMod or RasSaber (the first ROM comes with Saber-toothed-Squirrel kernel)
2. Purity (comes with Purified kernel)
You can find those, along with tons of other ROMs to choose from, here: http://forum.xda-developers.com/showthread.php?p=34474641
From your post I'm gathering that you don't want to mess around too much with the settings and just have a solid, stable system. The stock "look" is easily obtained by just flashing a new ROM and not touch anything in the custom settings, after all. Correct me if I'm wrong.

Lots of people are running stock rom (rooted) with a custom kernel... You can even find pre-rooted/bb'ed stock rom like this one:

No such thing as a deodexed kernel. All custom ROMs are deodexed.

My battery life is better on stock. Is that weird?

So I was running stock for a very long time, and I had insane battery life. I usually got 5 and a half hours of screen on time with my usage which mostly included browsing and a bit of youtube-ing and maybe the 30-40 minutes of gaming. I never used it conservatively though, I just didn't need anything else. I had GPS and bluetooth off and I used WiFi only at home (2g, not 3g, when outside).
Anyway, a month ago I flashed PA 3.99 and my battery life has reduced. I only (relatively) get 4 and a half to 5 hours of screen on time. Is this normal? I thought I'll get better battery life with a custom ROM. I'm still running stock kernel BTW.
PA is giving me too many issues including random reboots so I've decided to flash either CM, PSX, Carbon or PACman (help me in deciding from these?). Should I flash a custom kernel too? I'm leaning towards Faux for the battery life but I'm scared it might reduce it!
PS : I just flashed the PA ROM, so I'm still running the stock kernel, right? The thing is, on my older phone, some devs bundled the ROM with a custom kernel. My kernel version says 3.4.0-perf-g04b6fae. Sorry for the noob-ness.

There are just too many factors, the coding, apps installed, kernel, optimization, the user usage pattern, signal quality. It wouldn't surprise me though, but if it work for you stick with it.
Kernel alone doesn't determine the whole picture. I don't use PA, but I don't think it use stock kernel since stock usually ends with "mtv.corp.google.com".
You can check these battery life benchmark for kernels if you want to try, however, I don't go by them: http://forum.xda-developers.com/showthread.php?t=2449982

I did exactly the same, and feel exactly the same... I have the same apps, same usage, and I feel like I have a few hours less with this ROM (and same Kernel). I'm planning to give Franco a try, I think, although according to that benchmark it won't give a great battery life either... Have you already tried anyone?
Just a noob question, I haven't yet completely understood that thing about builds. When I was completely stock I was in JWR66Y. Then I only flashed PA 3.99 RC2 (for that build) and now in settings it says JLS36G. It now means that I have to care that kernels get on well with JLS36G? I thought I would stay in JWR66Y.

there are two versions of 4.3..one is stock (JWR) and one is AOSP (JLS)
the AOSP build is more latest in a way..AOSP build has more speed but has random freezes for 2-3 seconds (should be fixed in most of the roms by now) while stock JWR build is not as speedy as AOSP but doesnt have those random freezes.
And yeah you would now have to flash a JLS kernel rather than JWR..and if you want a kernel with good battery life..try hells core kernel which IMO has the best battery life and performance

after trying multiple different ROMs, kernels, etc.. I found that I wasted a lot of time getting geeked-out over nothing special. Sure, it's fun.. exciting... learning.. some minor features that are cool.. but, I do desire to have those hours of life back. Also, I experienced many more downsides than positives. Battery, lock-ups, random reboots, etc. A rooted stock device has served me very well..

Thanks! I had read about the difference between AOSP and stock, but didn't know/remember that JLS always AOSP. I think I felt this one better than stock. I've already been 4 days with it and I'm really comfortable being able to change dpi individually, custom it and use Pie, too, and stability is just as in stock, I think (I only got restarts in both of them while using Skype :S ). I didn't even worry to try CyanogenMod (in all my previous phones I had used it, always).

That's my concern in trying with new, custom kernels. Right now I'm just fine (although I'd like to have a little better battery life), so I'll keep reading and see if it's worth changing the kernel .
Thank you!

the hassle come with flashing a new rom because you have to do a factory reset..with kernel though its pretty simple just wipe cache/dalvik cache flash kernel then reboot. So just try the kernels you think are interesting and if youre not comfortable with it then flash another one..i know its a hassle with rom but not much with kernel.
P.S you guys should really try hells god kernel. Ive been personally using it for 3 months and the battery life is just amazing

I'm getting good battery life with KitKat.

Yeah, I've already flashed kernels in other phones, but never had this risk of compatibility issues due to different builds.
I've read that JSS kernels in JWR roms cause problems. Is the opposite not true? I mean, right now I have a stock JWR kernel running in a AOSP based ROM (JLS). Could this compatibility problems cause boot issues too? Of course, always with tested kernels. Or I'll always have the opportunity to boot into TWRP and flash a new kernel, until one works?
And one last question. When I look for AK's 4.3 kernel I only read JWR and JSS. Why doesn't it say JLS? Is it the same as JSS, then?
Thanks!

I can vouch for the above statements. I'm liking Hells core kernel. It's fast and has great battery life (as good as stock, maybe even slightly better). FWIW, I'm using Carbon ROM now and it's MUCH better than PA.

Sorry i forgot to mention that JLS and JSS are the same build JLS being the latest one..so there is no difference in JSS or JLS. You can flash a JSS kernel on a JLS build no problem. But if youre build is jwr then your kernel build should also be jwr because yes it causes compatibility issues if you flash a jwr kernel on a jss/jls build or vice versa. In every ROM the stock kernel is matched with its build number. If its a jwr ROM then the stock kernel would also be jwr and vice versa.
Flashing a jwr on a jls/jss rom or a jls/jss kernel on a jwr rom might cause the phone to be in a bootloop (not going past the bootanimation) and even if you get it to boot up the performance would be lacking and it might cause random freezes, graphic glitches and or random reboots.
However there are some roms that are a hybrid which means its a combination of jwr build and jls/jss build. In that case you will flash a jwr kernel only nothing else.

smooth and fast in nexus 6p

Wich ROM, mod, kernel or combination of two of them give me the best experience in android?? I m looking for an Android system fast, smooth and best battery life. Thanks to all

If something was the best, nothing else would be used as there's no point in using something that's inferior when you can get something better.
There is no best, I suggest you read each thread and pick one that suits your needs. Saying X ROM and kernel is the best is like saying a specific vehicle is the best...One may say a Ferrari and another may say an F-350. But who's right?
Some people like roms and kernels bloated with 1000 customization options filled with placebo "optimization and enhancements". Others prefer a clean, minimal ROM without all the useless bling that they'll never use.
P.S. there's probably 10 threads like these, and possibly 11 by next week that you could've read through. I'll just copy and paste this same post on the next one.

Currently using PureNexus nougat with ElementalX kernel. The experience is pretty good.
Using the phone for SMS/MMS, YouTube and web browsing. I can get ~ 5/6h sot with a full charge on WiFi and ~ 3h30 sot on 3g/LTE which is enough for me.
Also using custom CPU governor profile in EXKernel Manager helped me with battery life without affecting performance (at least not that I noticed). You can find more infos here:

F2FS + Dark ROM + FLASH kernel ! That's the best combination and I am a serial flasher

These people that are saying there isn't a best ROM, I don't really understand the reasoning behind this. There most certainly is a best ROM kernel combination. Otherwise all these ROMs and kernels would be exactly the same right? Sorry to say, some are better than others. This is just a fact.
If you want speed, smoothness, glass, breakneck speeds, great battery life, there really is one only choice.
Uber rom by Chad and faster kernel by Chad.
Why?
On f2fs, (trust me, you want f2fs) I have yet to find kernel or ROM combination that beats this.
Its the only rom that's built with GCC 6.3.1, and the only rom built with clang 3.9.1. Coupled with f2fs, this rom FLIES.
I have flashed every single ROM on this forum and then some, and I'm telling you this is the best combination you can possibly hope for:

Uber rom by Chad I definitely agree is the best. I tried using his faster angler but it caused problems with mods like viper4arise so I am sticking with flash kernel. Uber by Chad is definitely the best rom though and I have tried so many roms like pure nexus, resurrection remix, dirty unicorns, sixRom, lineage, cyanogenmod, nitrogen, Cortex and so many more.

Is the stock camera working on either Uber or Dark ROM with f2fs file system?
Thanks

There's no such thing as a best rom fact, but only best rom opinions, which isn't a good idea to ever discuss here. [emoji14]
As for battery, that all depends on you as a user to manager your battery life your way. I get 4+ SOT easily and I listen to a lot of music and text a lot.
As for what I'm using, I'm running ABC Rom with franco.kernel, root, and V4A. ?

I basically just wiped cache and dalvik/art cache and flashed the rom and kernel and all my mods. I also made sure to do stuff like rename audio effects and everything I did to make it work with flash. I use stable 2.4 deutronomy aroma installer. I was talking to someone else on this rom and kernel and he said he had the same problem too so it might be hit and miss or maybe you flashed it different than us. Please tell.me what you did to get it to work. Thanks

What partitions do you guys convert to f2s besides cache? Data as well? Everything else remains ext4?

Running stock has been great for me lately. Downgraded to 6.0.1 running Xposed for pixel mods. Amplify and greenify. With exkernel has been a great experience so far. Near 7h SOT yesterday. Will be going back to 7.1.1 soon, as the February update is out.. I heard lineage OS has good battery life. Will be trying that out soon in a few days.
Read the threads on XDA and good luck!!:good:

[Discussion] Favourite Kernel and Why ?

We have another post for ROM. Why do we not have another post for Kernel ?
As we can see, we have more than 5 kernels that are from XDA developer or someone else. But which one is really good for your ROM and which one still keep updating ?
I have been using OP5T for 2 months. Have used so many kernels but i still got stuck in those and do not know which is more stable. I am planning to use the kernel from Blu_Spark. Is that good ?
Post your favourite kernel and tell everybody why you use that. It will help newbie to pick what they want.

I am using Flash kernel at the moment but I have already tried Blu, franko, arter, ElementalX etc, but honestly for me it's difficult to see any difference since this phone have already a great battery life and great speed. On my previous phone (S8) the custom kernel gives a big advantage since the phone have tons of bloat and and isn't running stock like Android.

I have tried Blu and Franco for now and both have been very good. I really think kernel performance depends on the combo with the ROM as well as your device. I'm on Liquid Remix with Franco currently but I may give Resurrection Remix a try with Flash. If I had more time, I'd flash every ROM with every kernel to get a feel for all the possibilities LOL. :good:

For me Franco and flash kernel are the Best.... Now with ob3 with Franco kernel
Enviado desde mi ONEPLUS A5010 mediante Tapatalk

Did the Franco improve battery or performance? Someone Tried the Boeffla?

At the moment, both Flash Kernel and RenderKernel are great options in my opinion. I have tried most of the other kernels on xda and if you are looking specifically for smoothness/speed, these are the two you should test first. I do not run battery cycles; everyones daily use scenario really differs too much.
Flash Kernel currently has some kernel features I need (Kcal support & wakelock blocker) while RenderKernel does not have these features quite yet. While it lacks in some features, RenderKernel is undoubtedly the smoothest kernel for 5T right now.
I am on a 5T with OOS 5.0.3.

I like Franco but recently some custom ROMs have WIFI cannot turn on problem after I flash Franco kernel.

With it's options to adjust for extreme brightness, it quickly became a favorite a couple years ago and I've just stuck with it since.
Now most devs are adding high brightness to their kernels.
I guess I can start checking other kernels out.
I do like that ElementalX stays very stockish, reliable.
I can pretty much flash it and feel confident nothing weird will pop up over the next few days.

ElementalX, Franco, and flash were all my go-to kernels back in the 6p days (just a few months ago, lol), so it's hard to pick, especially since they all ended up on the 5t. Right now I'm on exkernel though I am partial to flash. Battery life is amazing on all 3, but the overclock on ex just adds that extra bit of smoothness that I've never experienced before. Call it placebo but I just love this kernel (exkernel).

any more input?
im curious to know if fsync affects battery performance at all, can someone also test this out if you are on a kernel that enables disabling the fsync feature

Tried it but didn't notice any difference.
Technically it should improve performance when using the phone, but it won't be noticeable.

simple and steady, close to stock for daily using.

Does flashing a custom kernel solves Google play services battery drain?
Do I need custom recovery and root to flash a custom kernel? I'm not willing to play with kernel adiutor so I'm not really interested in rooting

Custom kernel has nothing to do with google play services. You need custom recovery to flash a kernel, but most kernels for op5t are "flash & forget" which mean there is no reason to change the setting of the kernel.

maybe not Google play services specifically, but with my latest phone (zuk z2), kernel was directly related to deep sleep
stock OOS/kernel has a serious issue with Google PS in terms of deep sleep. Besides that, I dont feel any need to flash a custom kernel. SOT is incredible already, and performance is really fluid.

If you are OK then there is no need to flash a kernel. If an app is crap (like Google services or facebook) the kernel can't do miracles and its not kernels job to control wakelocks of user apps

I keep changing between blu and new kernel
Not sure which to stick with but I think new kernel gives me a bit more battery
