[Q] Kernel Help? (2.6.35.7-g8f2a88c-dirty)

Hey guys!
I recently got a Rogers captivate (I896) and have been playing around with it lately... Currently it is running CM7... I followed these steps to put Cyanogenmod on my phone (http://wiki.cyanogenmod.com/wiki/Samsung_Captivate:_Full_Update_Guide) I've been reading up on kernels, and am pretty interested in changing the kernel... But when I checked the kernel, i had a kernel named 2.6.35.7-g8f2a88c-dirty [email protected] #1... I did some searches but it came up empty... What is this kernel?
I've been looking at Glitch, hoping that it would improve battery life...
Thanks for helping me identify!

With a few quick searches it seems that that kernel is the one that CyanogenMod uses as the stock kernel, I don't have CM7 on mine but take a look in the dev forums and you can see other kernels and read a little about the differences. Then choose the best one for you. And if it turns out it isn't the best one for you flash another.

KK, thanks... I was wondering why it was like that... Does installing roms influence kernels? It shouldn't right? When I followed the instructions it said I was installing the SpeedMod kernel...
Well, thanks for your help! Now I need to look for a different kernel... My battery life is only around a day, if i let it idle.... Thanks again!

Your welcome and hit the thanks button. As to your other question most roms will come with their custom kernel cooked in some will use the stock kernel but almost all roms will change your kernel when you flash something new. Kernels and roms are completely different things but you can't flash a ROM without a kernel. But you can flash a new kernel without flashing a new rom. Just make sure that you read read read. So that you don't end up bricking your phone.

btw cuz i just rooted the other day wat is the best kernal tht i should use

gnufabo suggests stock but i think blades 2 is the best

With the latest firmware update, all custom kernels have become unstable, including blades. People have reported their TF locking up with custom kernels. The only custom kernel that isn't unstable is clemsyn v21. Unfortunately, there's a battery drain of the dock with this kernel.
For now, until the kernel devs figure out what the hell is going on, the best thing for yout to do is use the stock kernel.

I havent had issue one with Roach's overclock kernel set at 1.4

This is certainly good news. What's happening is that different people are reporting different results.

I think blades 2 is OK haven't had problems but I'm just gonna go back to stock ;-)

Using Prime v2.0.6 kernel since Monday and it is stellar. No problems whatsoever. 3300 on Quadrant too!

I've actually been just fine with the Blades 2 kernel... No issues whatsoever - not even any excessive battery drain. OC'd to 1540.

Questions - roms/kernels/themes

Hello, I'm brand new to all of these roms and such, I've got a rooted 2.2.2 froyo g2x/lgP999. I am interested in getting a rom and a kernel. I am interested in getting ginger bread 2.3.3 and overclocking along with more battery life and a theme. Could I be linked to tutorials and suggested roms/kernels, and I have looked around but i really have no idea what im looking at so please don't say you've done nothing and are making us do all your work :\

Hi there,
If you don't have cwm recovery installed on your phone follow the instructions on this thread http://forum.xda-developers.com/showthread.php?t=1056847 to flash it.
Then pick one of the following 2.3.3 roms and flash it following the instructions provided on the thread:

There might be more 2.3.3 roms available in the development section, also you might wanna consider flashing a 2.3.7 rom, if so check out the development section and pick one, or try several roms and pick whichever one you like most. Devs are more active with 2.3.7 roms, so you'll find better support and more features.
As for the kernels, you can usually overclock your CPU with any custom rom (provided you get the appropriate app from the market if there are no OCing options built into the rom), but I haven't used a 2.3.3 rom in a long time so I'm not sure if OCing is available with the stock kernels they come with. If you do go with a 2.3.5 (or above, namely 2.3.7) rom then you can try either:
Morfic's kernel http://forum.xda-developers.com/showthread.php?t=1078049
or Faux's kernel http://forum.xda-developers.com/showthread.php?t=1073626
They're both excellent kernels, Trinity (Morfic's kernel) has a known issue with rebooting, the phone will freeze every now and then when you try to reboot so you'd have to do a battery pull.
Faux's kernel doesn't have that issue, but, for me at lease, when trying to reboot into recovery it does a normal reboot instead.
As you might already know, the G2X has a somewhat crappy battery life, most people can't get more than 24-30 hours of battery life with the stock battery, and from what I read most of the custom batteries aren't as good as advertised, so your best bet is to use an under volted kernel and try to find some battery tweaks in the forums.
There's way too many themes to list here but basically, for CM7 roms you can look for themes in the market, and for MIUI themes you can use their themes app to find something suitable.

A note on overclocking:
Please know that not all phones respond the same when overclocked. In other words, some phones can't handle the same overclock speed as other phones. And also note that overclocking sacrifices a bit of battery life to increase the performance, the extra juice has to come from somewhere. I suggest starting from the stock kernel of whichever rom you choose, see how your phone does on a stock, unmodded kernel. If you want a little more performance, then you can flash a custom one and slowly increase clock speed over time to see how your phone responds. If you want more battery life, then you should read up on UV (undervolting) settings in the custom kernel. The key is to try and find a nice combination of both so you can benefit great battery life and performance, but requires some tinkering and testing to get that right combination. Just something to note.

Phoenix Blood 1.7 with Faux123 048 kernel is the way to go. Do some reading on Google how to nvflash cwm and do a Android backup. Also titanium backup your applications and your golden.
Making bad decision's one at a time.

Thank you all for the fast response.
Now I have a question, are kernels used to acheive anything other than overclocking/undervolting? And are there any for 2.3.3 roms, if so which would you recommend?

Yes, your phone won't function without the kernel (obviously) and custom kernels are better than the stock one in that (in simple words) they improve performance and power consumption (kinda like drivers for computer parts).
I think the following would work for 2.3.3 roms, do a nandroid backup and try it, if it doesn't work just restore

I get better battery life on Eaglesblood 2.3.7 and Trinity ELP kernel (overclocked to 1.1GHz, normal is 1.0) than a stock based rom, like Weapon, will ever get. And on T15 kernel at 1.56 I can still get pretty damn good battery.

Cant seem to find the t15 kernel, not in the kernel list.

I run overclocked to 1.6 with a pretty aggressive undervolt. With the right profiles in setcpu I get better than stock battery and very very good performance.

Go to http://www.derkernel.com/ and look under current G2x kernels for 2.3.5 builds. There's ELPmax, T15max, and TD158. Don't flash any of these kernels if you're on a 2.3.3 rom though. Good luck

That is impressive but i would defiantly not recommend doing that if you are just starting... That can cause extreme instability...
If you want to undervolt start small and work your way up in increments making sure to not have the settings to "Apply on boot" that way if you get a crash (And you will until you find the sweet spot) you wont be stuck with your phone crashing over and over because the cpu/kernel is freaking out
And SetCPU is a great program for OC/UV for any rom

question i cant seem to quickly find about undervolting:
when undervolting in pimpmycpu (SetCPU crashes on me when I go to voltage settings for whatever reason) do you undervolt each setting? Like -50mv for 1.4GHz, -50mv for 1.2Ghz, -50mv for 1Ghz etc etc etc.. or just -50mv for the top (1.4Ghz) setting?
Oh, I'm on Faux's 048 kernel..

You only undervolt the clock speed you're using, you can do it for both min and max values, or just for one. But if you use multiple OC profiles, then you can UV every clock speed you're using.
Either way, UVing all clock speeds shouldn't cause any issues, but it wouldn't help much

[Q] Best Kernel for ICS on G2x?

I've recently flashed to an ICS rom, and I am now trying to figure out what the best kernel is to run with it (I'd really like to see one that maximizes battery life.) If you are running ICS, would you mind please posting what ROM you are using and what Kernel you have along with it. Also, take a second to explain the pros and cons of that Kernel so we may all make more informed decisions as we prepare to potentially flash one...
Thank you kindly!

Mr. Apocalypse uses Harsh's kernel for Genesis. Owain uses Harsh's kernel for his ICS build. x0xhellx0x uses Faux's kernel for Hellfire Sandwich. I think you can use those as starting point. I like Morfic's Trinity kernel because you can OC to 1560.

Everyone is. NVIDIA has yet to release ICS drivers... so there is sub optimal video on all ICS builds.
We await the official release.

i would recomment the harsh kernel 1505 oc i love it smooth nice battery. i'm against faux it's good in battery and fast, but when you try doing too many stuff it starts hanging
