Favorite kernel?

I'm running the stock kernel right now with Android Revolution ROM. Anyone have a kernel on their GNex that they really like?

You're pretty limited as most of the kernel developers have gone on to 4.0.3.

Pretty much what he said. Your only alternative is to use MoDaCo's 4.0.2 ROM allowing 4.0.3 kernels. But I'd just recommend using AOKP, its on 4.0.3 and you can combine that with Franco's kernel. Amazing combination and I recommend it.
I was using ARHD but he never updated to 4.0.3 as he's waiting for the binaries for 4.0.3 on Google's part. I don't fully agree with what he's doing so I moved onto AOKP. AOKP offers a lot more features that are amazing and every update just brings on new features that I really like. So you should check that out

If you want the "leaked" 4.0.3 from somewhere, use one of those rom, but might not be stable. I am using arhd with james bond kernel with 1.35 oc uv, it run like better, no crash, stable like stock. The choice is your, stable or not stable. Most of the rom out there are just diffetent name but 99% are the same.

4.0.3 is not leaked. It's compiled off AOSP source. And it very much stable. AOKP is also not the same as the other ROMs. Unique features such as changing color of the clock, adding PM/AM, smaller PM/AM, center clock, power saver are there. This is what separates this ROM from the rest.

Gotcha, thanks guys. There are are a few things I've been wanting to do with 4.0.3 anyway, so maybe I'll bit the bullet and switch to a different ROM. I looked into AOKP and Franco's kernel and they both sound pretty good.

Just took the plunge - AOKP with Franco's kernel. It is sa-weeeet!

ya i donno where you're getting your information from but running aokp has been the smoothest, most stable rom experience I've had.

Using ARHD 2.1.1. Since it's 4.0.2 you're limited in available kernels since most are being developed for 4.0.3. But with that said I'm using Jame Bond Kernel w/ 1.35 oc and uv.
Only had one fc, other than that it's been very stable.

Another quite popular ROM is Bigxie's 4.0.3 based one (http://forum.xda-developers.com/showthread.php?t=1399238).
Along with Franco's kernel, this combination really flies, with great battery life!
I highly recommend it. Franco also has a market app which makes updates more convenient and also offers easy access to options such as overclocking.

Franco's is awesome. He has a handy auto-update app on the market.

Just installed it does this auto-check for you, or do you have to manually open it to check for kernel updates?

Galaxy Nexus Kernel?

Hey guys,
recently rooted my phone (for the first time) and flashed CM10. I've been reading about Kernels and how they can improve battery life and performance and stuff.
I haven't really understood how a kernel would work. Can I just flash it like how I flashed a ROM? Would it 'delete' my earlier CM10 kernel?
Which kernels are compatible with CM10? Which is the best for battery life and snappiness of the processor?
I've heard of Lean,PopcornKernal, and of course, francos.
Thanks,
Sahil

All of them are good. There isn't a best kernel. You should really stay away from asking those questions. And if you don't tune the kernel there is no way to get any difference than from stock.

Im not sure if cm10 requires its own set of kernels but my phone liked the air kernel (ran cooler) and lean (as a bonus removed the purply tint at lower brightness)

depends on the kernel, on the device and on the user.
mpu/core/iva voltages, smartreflex and color control are a few examples.

kernels are like the engine to a car/rom. They're pretty much what manages and drives everything, whereas the rom is like the entire OS.
Every ROM comes with a kernel by default but it can be replaced simply by flashing a kernel on top of it. Conversely, flashing a rom will replace whatever kernel you're running now with the rom's kernel.

Many kernels come with their apps (which can be found in their threads), or some apps might have access to some properties. Also, some roms (cm comes to mind) have access to some properties of some kernels, though there was a recent fuss made about incompatibility so its not perfect.

Franco Kernel
Hey guys! I want to root my GN and I'm a bit confused about what Kernel use...
I have seen this: http://forum.xda-developers.com/showthread.php?t=1367341
Did anyone try the newest version of Franco Kernel (r292)? What's about stability, battery drains, lags... ?

I'd recommend trying Franco's kernel out, it is supported by a nice updater app that can auto-flash the kernel and keep you informed of updates. Doing a bit of research yourself is also always recommended here - this site is for learning about your device. Good luck!

James bond kernal claims to be best in battry life , bt acc. To me trinity alpha 67 with setcpu profiles provide best results.

i747M - Best ROM and Kernel

Hey guys,
What is the best rom/kernel combo you have found? I am currently on slimbean with kT kernel. Looking for what has worked for others :good:

+1
I'm very interested to know myself. I just got the sgs3 coming from a galaxy nexus running aokp. I love the new touchwiz which is ,I find, leaps and bounds beyond the sgs2's version of touchwiz. I actually want to keep it. I want a rom that gives me more without taking anything away. What I mean is a juiced up touchwiz with more customization. No nova or apex. Lte, avcrp and nfc that actually work. landscape mode phablet mode etc. Every rom has one or the other not all.

at this point it really comes down to personal opinion. all roms are heavily supported and seem to be very stable. it depends on what your looking for.
slim is a great rom very smooth and light (only ~80mb in size!) but i've found that i get more random fc's on slimbean than i do on cm10/aokp. so im sticking with cm10 & kt747 kernel for now. i always check out new slimbean updates though, when it gets a little more stable ill probably stay there.
i haven't had much experience with leak based stock jb roms. when the official at&t jb update comes out ill probably stick with stock jb because i do enjoy touchwiz but right now it seems that aosp is better with stability and battery life.
one thing i am sure of is every rom i flash, i flash ktoonsez kt747 kernel. during heavy use i switch to from ondemand to ktoonservative governer and that will really save you battery life.

i think it does come down to personal preference, but what I'm using is the latest Cyanogenmod 10 nightly with Ktoonsez latest kernel (9/23) and it's underclocked and undervolted. Great performance and even better battery life.

Serenity is based on the note 2 software. Milestone is based on the tmobile s3 leak. I tried both and went back to an ics rom (ariel). It just seems more stable and has more of the features that i like.

I really like Serenity v1.1 located at http://forum.xda-developers.com/showthread.php?t=1869300.
There are a few bugs here and there, but nothing that would prevent daily use in my opinion. If you are after super stable then you should probably stick with a stock-based ROM of which there are plenty. If you want to try out JB then I'd give Serenity a shot.

I use kt747 with stock rogers rom, (4.1.1 JB). Aside from a couple of issues with charging for while powered off, everything is working well.

Jedi ROM 2.0.
I've had 0 issues with it, great battery life, buttery smooth (using Nova launcher) and everything works flawlessly.

There is no such thing as best. My phone and your phone are not identical, even though they may have very been from the same production lot. Nor are the individual circumstances under which two given people use their phones identical. Something that performs extremely well on one phone may very well boot loop on another.
Do some research by reading the applicable dev forum, and then try some different combinations for yourself to see if they work for you under your unique set of circumstances.

I am using Cataclysm ROM with the inbuilt kernel that comes with it and I am completely happy with the battery life.
I could get 2 days out of my device on general usage.
You could try that.

I REALLY doubt you will get the BEST battery performance out of stock.

KERNEL.

there is no best combo, there is only the best combo for you and your device. for me its rasbean jelly rom with trinity kernel. but whats best for me and my device might not be right for you and your device.

I've been using cataclysm with Franco kernel for a while and have been very satisfied.
Sent from my Galaxy Nexus using xda app-developers app

Agreed, there is no best. I've had good luck with muzzy's aosp room and Trinity kernels. But you might not like that combo. I'm not interested in gaming for instance, so my needs might be different than yours. Try different combos and you'll discover your own best.

Ok.. got it.. thanks everyone

stock rom is the best in my opinion

I think Xylon (014) with the default lean kernel gives good battery life. Tried the ROM with Franco 358 but i went back to lean.
Also, i make site that my most of my apps aren't running in the background and using up the battery... That's what the FAQs from Franco's OP in his thread mentions.
Sent from my Galaxy Nexus using XDA

I get over 5 hours screen on time and a flawless smooth ROM with heavy usage with both data and WiFi on with xylon stable and ak purity kernel running Wheatley gov. I just addressed this on the xylon thread. Works well for me and some others.. Have a look its worth the flash to see.

Check my sig. I can't use any rom other than paranoid. I've tried many different kernels, but i keep going back to Franco.

Whatever combo I use, no more than 2hrs of screen time and 16hrs of standby.

For me it's I've been on Muzzy's French Vanilla on stock kernal. However, I've read good things about tiny's kernal too but I haven't tried it myself.

As a noob in the android community, and after trying different roms, i like rasbean the most for different reasons, but on choosing a kernel, for example trinity, there are a lot of options. What's the difference? I really not get it :silly:
for example, TNP1536-512-JB-4.1.2-STABLE67
So this one is max 1536Mhz CPU and max 512 GPU i read on derkernel site
So there's a different setting for graphics (gpu)? I always tought CPU was working between 1536-512 Mhz?
And euh, when i have trinity's app, i can change the settings of this kernel to get this one? (TNP1344-384-JB-4.1.2-STABLE67)
So this is the same kernel but with different settings?
Please make me a little bit smarter

[Q] Question about Leankernal+Paranoid Android

Hi!
This is my first post on the xda Forums; I've just been a lurker for a while now. I am still learning the ins/outs of Smartphone modifications/rooting/roms etc, so forgive my noobyness.
I've recently (two days ago) Rooted my Rogers S3, and Flashed Paranoid Android 2.55 Onto it. I'm loving it! However The battery life is something I'm not too keen on, so I've been lurking google for hours upon hours, forums etc, and I'm seeing that a popular Kernal people are using to cut down on battery drainage + Smoothen things up, is LeanKernal.
+
Now, I've poked around quite a bit, and I've read through something like 75+ pages of this topic: http://forum.xda-developers.com/showthread.php?t=1845836
But just for the sake of not Bricking my phone / Digging a hole I'm not educated enough to get myself out of; I'd like to ask:
Is LeanKernal what I am looking for/compatible with, my P.A flashed Rogers S3?
Or any other tips for me?
Much appreciated!

Lean kernel is compatible with AOSP ROMs. The developer should have a clearly-marked download link.
That being said - if you can't find the answer you're looking for by yourself, don't flash it. It's very easy to brick a device by making one small mistake.

Lean kernel is designed for aosp ROMs but the new ones are based on a different Linux version. If you install paranoid android 2.55 with the newest lean kernel it will never boot. You need to either find am older lean kernel or flash the newest paranoidandroid.

All the kernels get updated frequently. I'm using the Paranoidandroid 3.15beta and Tasks latest Underwear kernel and it's working fantastic.
Battery life if device, app and user specific so you'll have to just experiment.

Don't apologize. We all start somewhere. When I get off work I'll look into which lean kernel you can use. Give ktoonz a couple charge cycles to see how it's working before you start tweaking any of the performance settings.
