[Q] (Q) ROMs and Kernels

Hey,
So sorry for what probably seems like a dumb question. I'm usually a Vibrant guy, but I'm helping a buddy out with a G2/looking at the feasibility of getting one myself. I know at least for the Vibrant our normal kernels don't play nice with our version of CyanogenMod 7. I was curious if the same held true here? Or can I flash any kernel? Also, I see that there are different types based on the type of ROM, which is a new thing to a Vibrant owner. So can anyone recommend me a kernel? I'm pretty decent on flashing and all that, and recovering a brick (at least with my Vibrant). Basically I want the best bottom-line performance. I don't need extra bells and whistles, just a nice high clock frequency. Thanks!

If you're looking for a kernel for CM7, the kernel included is quite snappy though I personally run pershoot's kernel as he undervolts and has some other tweaks which improves responsiveness *and* battery life, at least for me.
Sent from my HTC Vision using XDA App

CM7 already comes with its own custom kernel (which also supports some overclocking), so no need to flash a separate kernel if you don't want to. But as already mentioned, pershoot's works well too.
You can't flash any kernel. Some are Sense specific, and some are for non-Sense ROMs. Flashing the wrong one for your ROM can apparently brick the phone, so read thru the threads for the ROM and kernel you are interested in, to be sure. The ROM developer will usually have kernel recommendations, or you can see what kernels users of that ROM have tried.

Like stated above you will need to read the instructions and notes on the kernel thread. CM7 has special requirements. Other Roms don't need. but be very careful on what you flash!

Stock kernel vs custom kernel

Are there any advantages/disadvantages for using a stock kernel vs a custom kernel? Thanks for the responses.
Sent from my Modded Classic Evo... It's easier this way.

Stock kernel usually does'nt clock over 998MHz and you are'nt able to over or undervolt the kernel for better battery life.Also on custom kernels there are more governor options(smartass,etc.).Custom kernels can go up to 1118MHz sometimes higher,depends on the CPU.

I am aware of those differences. Basically, I'm wondering why I see so many people wanting to use a stock kernel (especially the one in the new OTA) and I was wondering why. Like what are the advantages of using the stock kernel over a custom kernel? Is it more stable? Are there any other things I may not be thinking of that would make a stock kernel a better choice? Thx again!
Sent from my Modded Classic Evo... It's easier this way.

I would think stock kernels to be smoother because they are designed for that particular rom/build,when a custom kernel is designed to run on different roms/builds,then when roms are updated or changed,the custom kernel does'nt,unless changed by the developer,hence the lag and FC's.I hope thats the answer you were looking for.

Custom kernels are made universal for several devices and roms. Although they yield benefits over stock, sometimes they can be unstable on certain setups. like mentioned above stock is made specifically for said device bout somewhat limited, though very stable

Thanks clicked for both of you. Reason I ask is because I am running the new radios that were released with the newest OTA and wanted to know what to look for when I finally give the new kernel a try. Has anyone used the new kernel HTC released with the OTA yet? Has anyone a comparison they could share? Thanks.

[Q] New to GN! Kernel Question

Hi everyone!
Well, I finally switched over from my Driod Charge last week. Prior to that, I had the Fascinate for about a year. So, while I am new to the Nexus, I am certainly not new to Samsung, Android or flashing... as of now, I have unlocked and rooted my phone, but other than that, I am completely stock (and not minding it actually) I am sure I will get around to custom ROMs very soon though. But in the meantime, I have a couple quick questions:
1) Is ALL flashing now done through ROM Manager or Clockwork Mod (i.e. No Odin?)
2) As said, I am still stock (4.0.2) but I would like a kernel to flash, not a ROM (yet!) that will allow overclocking, wireless tethering, etc... suggestions anyone??
Thats really it for now.... just wanted to say HI to my "new" community here on XDA!
Joe

1 for roms etc, yes (use cwm, not rom manager)! only use odin when cw doesnt work.
2 franco.kernel, trinity, glados, popcornkernel and leankernel are all great
And welcome

1) Yes.
Odin is used for MAJOR **** ups only.
2) There are one or two kernels compatible with 4.0.2 in the forum bit I think Franco's one is 4.0.3/4 only.
I think james bond kernel is 4.0.2 compatible.
3) Flash a rom, there are some nice roms to be flashed. Personally I use AOKP 4.0.3.

Yea, I am sure I will get to ROMs soon enough.... but coming from the Charge, the dual core in the GN makes it feel fast enough so as it is!
OK... so no ODIN.
As far as the kernels... any show better battery life? Really the only downside to the GN, but I do have a spare battery and charge, so Im ok.

I would suggest Imoseyon's Lean Kernel in conjunction with Lean Tweaks. I get good speed and decent battery life with it.

Thanks... but I think it says that Leankernel is for 4.0.3/4... I'm in 4.0.2. I'm assuming I can't use it?

James bond is the only 4.0.2 kernel I know of.
Search around though and you might find another.
If you want a stock rom that's 4.0.3 then flash bugless Pete's rom.
Its pretty much plain stock.

Kernels and your preferences

Alright, pointless gathering of information time! How many of you strictly flash a different kernel after a ROM flash? For example, I'm using liq*id 1.5 which comes with Franco kernel bundled with it. Now, I'm sure a large percentage here may agree, the guys have built a nice stable ROM and know what they are doing, likewise Franco is a dependable dev with a solid kernel.
On paper it sounds like a match made in heaven as they both have plenty of experience and i'm sure the liq*id devs chose it for a reason. However, I always go back to Trinity after about 20 mins. Am I a sucker for placebo effects? Does anyone else religiously go back to a preferred kernel despite the knowledge that most bundled kernels SHOULD/POSSIBLY give the best user experience?
TL;DR do you use a kernel most the time because you BELIEVE it will give you the best experience, or do you give bundled kernels a good run first?
Sent from my Galaxy Nexus using XDA

i dont know.. in my experience custom kernels have usually been better than bundled kernels, with cm being an exemption since the cm kernel is very important to cyanogen. on most the other roms, most of the developers really focus most their attention to the rom. anyways, i will usually run/try all the kernels(need to know what is out there and how it compares to trinity), but always go back to trinity since that where my heart lays, and home is where the heart is

Through some sort of sorcery and probably placebo, I've always noticed best results when I use a kernel that has its own ramdisk.

I'm not much for bundled kernels. I know what kernels work for me and how they work by trying them all out.
Currently, GLaDOS kernel is the one that acts best for me.

Franco Kernel... it's what I'm used to and I haven't had any problems with it so why change? plus.. I bought his app, so I'm dedicated to it.
And no I don't use bundled kernels. Just because the kernel comes with the ROM doesn't mean its optimal for that particular ROM. But it may come with ROM settings that are for that kernel (such as AOKP and "GNParts")

If you want to use AOKP 4.2.1 which is MR1 build 1 I suggest just upgrading the kernel they chose to go with...It wtill has some battery issues but if helped at least 30%

I use CM 10.1 with the CM 10.1 kernel. Best combo for me and my usage pattern

I don't use bundled kernels either!Last 3 months using AK Purity Kernel and it's really solid and does the job perfect!

I've been running CM 10.1 with the Air Kernel. Its been working great for me so far.

[Q] Need help with my VZW Galaxy Nexus!

Hey Guys!
I have a VZW Galaxy Nexus rooted and running on CM 10.2 (Have no clue what kernel it's running). The phone is great but i'm having a lot of issues. My battery life is very very bad! I know the phone's battery already is terrible as is but mine is really bad. It's becoming more and more slugglish. I barely have any ram free.
My question is what do ya'll suggest is the best ROM, Kernel, etc for me to have on it. I know its off of preference but what i'm looking for is an increase in performance overall. There is a lot ROMs and Kernels out there but I just don't which ones are the best to use. I've thought of a lot of things but don't know what I should do. Under-volt the CPU? Change the kernel? Run a lighter ROM? Basically what ever it takes to get my phone running like most of the newer phones till my contract is over lol. :fingers-crossed:
Thanks,
Alex

The best combination I found prior to getting my new phone is Shiny rom and leankernel

I ran aokp milestone (4.2.2) and either franco or AK. Right now on faircts PA 3.99 with franco. Unless you know what you're doing with kernels, I find franco to be an easy/good kernel to run that requires no tweaking. Also, disabling halo helps lag/speed

I accidently posted it in the wrong section so I posted it in the right section and didn't know how to remove it.
Thanks for the help

Ahh, I was looking into that kernel and rom. What do you think about paranoid? It looks cool but it looks like it will not run very smooth on the Nexus. Thanks for the suggestion.

I'm not huge in halo and PIE which is why I like aokp better than paranoid but since aokp is still on 4.2.2 ....
that being said, I like fairct's a lot. It's quite fast with franco (couldn't get golden to play nicely) and is usually smooth though I have to reboot every few days (standard for me). I tried a few other 4.3s and I definitely think fairct's is the best thus far. I also really like the cm-10 file manager which you can get on aokp but I can't seem to get it on paranoid.
I'll move onto aokp and/or illusionrom once it gets to 4.3 (illusionrom can't get the home button working...kinda dealbreaker) since I don't really care for halo. I'm using halo now but it's not doing much for me
