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.
I'm trying to understand my sensation, it's not the same as my G2 as far as overclocking goes and I'd like to understand why. I have full root and currently have Elegancia 1.4 up and running. With the G2, once I was rooted I could overclock up to 1.5 from the stock 800, but when I try to use setcpu with the sensation it only gives me an underclock option, the highest setting it lets me go to is 1.18
Am I doing something wrong, did I not do something I should have, or am I just stupid? I know benchmark scores don't mean much, but when I can get a higher quadrant score using my old G2 it makes me a little sad that I spent money on the sensation
you need to flash an overclock kernel like the one from faux123

Exactly, or you can also use Bricked Kernel by show-p 1984
Thanks for the quick answers. So if I've read right to change my kernel I just download it to the sd card and flash through recovery? I've tried to understand the differences between the kernels but I still don't really get it, what makes faux different/better/worse than bricked?
idk te differences really... i switch between them but you just boot into recovery and flash just like u would a rom
OK, since this was moved to the "question" section I'll ask a straight up question, what makes the kernels different from each other? I've searched and still didn't find any type of "kernal comparison".
How would i got about flashing a new kernel?
im using this tutorial http://forum.xda-developers.com/showthread.php?t=1376027
and will flashing a kernel trip the counter?
are all kernels compatible with all roms?
can i use an att kernel on my 727r?
and which kernel would you reccomend? i hear a lot about Da_g?

Flash the Kernel thru CWM and you wont have to worry about the counter.
no Not all Kernels are compatible with all roms, but we only have four right now any way. and one is a CM7 kernel so you only use that with CM7.
the others are Romracers stockish kernel, Da g's OC kernel, and the Stock kernel itself.
just read the kernel OP it will tell you if its for rogers or at&t.
i personallly dont like to recomend roms and kernels....so my advice is flash away and find one that you like
good luck
thanks for the reply... im interested in the oc kernel, have you tried it? and do you think its worth it to oc? is it stable? i know its has a fast processor on stock so i dont know if overclocking pros really outweigh the cons.

i personally LOVE to OC, but Da G's kernel does have its hikups....and i have been using his Kernels since 0.1 and its now on .43 the overclocking is great, it does seem to make the roms run smoother, but i seemed to suffer alot of SOD's while using his kernel. but they are patches that you can run, like the one in TPCs Rom Thread that may fix that.
but not eveyone experiances the same stuff. again i would just try them and you make like them.
the stock kernel is fast though, but once we get a stable OC kernel believe i will be oc'ing to the max trying to melt my phone.....
Just flashed the CM 7 kernel with the Sky Ice Cream ROM. Now my phone won't go past the Samsung boot screen and I can't get it into recovery. NEED HELP PLEASE!!

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
Been flashing Custom Roms & Kernels insanely these few days trying to get the most perfect Custom Rom and Kernel. I have decided to use ViperS 1.1.0 as my main Custom Rom, I'm now deciding which Kernel best go with it and that's it, I can finally starting doing my stuff on my phone instead of searching for Roms and Kernels everyday to flash. Lol, after rooting my phone, I haven't like used it yet at all, all I did was looking for Custom Roms and Kernels to flash to find which best for me.....
Well anyway, can a ViperS 1.1.0 user please tell me which Kernel is good? I'm looking for a Kernel that has good battery life and a bit good performance. I have tried many Kernels but can't notice the difference between them.
Also how would I change the Kernel's settings? Like if I want to change the Governor, how would I change it?
Thanks in advanced! I'm kinda new to Kernels.

Yeah, I've seen many people say that Sebastian's kernel is best for ViperS 1.1.0. But when I download Sebastian's kernel and install it, it doesn't have an installer for me to choose options from? It just installs it and that's it, how would I like change the settings for it?
You can use a mod that goes with the Sebastian kernel, this is what I did. Its supposed to help battery life. Check out the mods and you will find it. Best wishes.

As some people already said, Sebastian`s kernel is very good. His kernel + as much Undervoltage as is stable for your phone should make a good performance with good battery life I`m plaaying Dead Trigger with Tegra effects enabled, and no lags with -75mV, but you need to find out what UV level is good and stable for you
and BTW guys, what mods are you talking about? I looked at his thread and didn`t find any mods. Do you mean that OC and ZRAM or there are any other mods?

For kernel settings such as govs and uv, you can use an app such as system tuner. It allows you to change a multitude of kernel settings, including clock speed.
sebastian fm is good kernel... +1
I am talking about all from my signature
Sebastians kernel doesnt offer any options to choose as I know.
The same with MOD Take Control - but you may change some things by System Tuner app.
There is a link to a MOD for seb's kernel in the viper thread, posted not so long ago. It allows you to change a whole bunch of stuff for his kernel such as uv and even second phase frequencies. It's a seperate zip you flash after flashing the kernel itself.
