I'm running CM10 nightly, and wondering if I will gain any performance improvement (without OC) and longer battery life if I flash one of the alternative kernels on XDA (looking at Devil and Semaphore as those seem to be the most popular)?
yes and yes, but it all depends on how you configure the kernel options and how you use your SGS...
Sent from my GT-I9000 using xda app-developers app
yes, definitely!
but to get the "best" result, of course you have to let it settle for atleast 3 days..
here is a youtube link on how to flash them: http://www.youtube.com/watch?v=kCBN-_zu5cY
i hope this helps,
cheers
Thanks for the answers. I was hoping for recommendations, do you have any?
Semaphore is looking good to me. Opinions?
I'd go with semaphore for ICS...
But for CM10 I'd use Devil..
But that's just me

If you want stability then semaphore.But if you want more tricks to make your phone even faster it is devil of course. There is one more kernel to try Mackay.
Test each to get the right one for you.
Sent from my GT-I9000 using xda premium
Semaphore is the one you need .
What else from having great speed with stability. Yeah, maybe Devil could provide some more speed, which is unnoticeable, for me at least.( except the benchmark tests )
Sema is the most stable one.
But devil isn't bad too.
Try them. But give your phone about 5 minutes after flashing and don't be frustrated when it's a bit laggy after first reboot.
Last days I tryed makay. --> I prefer sema

I prefer devil. My phone still lasts a whole day (7am - 12pm) and is much faster. I like all the options.
Sent from my GT-I9000 using xda premium
On JB roms i always use the devil kernel even if the Semaphore is a very good kernel, Devil kernel allows me to entirely use my phone's habilities with no more battery drain than Sema
you will instantly notice more speed and smoothness with flashing semaphoer kernel.
+ more speed if you set up liveOC to 114%
Does anyone have any links? I'm using CM10 nightly and need a kernel so that BLM and Voodoo sound will work. I tried the latest semaphore 2.8.0 via Odin but the phone would not boot.

You should read the description more carefully. The 2.8 kernel is for JB 4.2 not CM10. Flash the 2.6.5 kernel.

I have few more questions...will i flash only kernel or i need to flash the rom together with kenrel...and can i use odin to flash kernel?Sorry for all thease questions im noob guy in this area
You don't have to flash a rom if you're happy with the one you're using. And you can download .zip's and flash in CWM if you like, but I've found that the only times I've ever got into a boot loop when flashing a kernel are by doing it this way. Not that it has happened often. But for that reason, i prefer to flash my kernels .tar in odin, I've never had a problem doing it that way, but whatever way you choose to do it take a nandroid first, just in case.

Download semaphore manager app if you haven't already done so. Also, if you used the (s) version, you need to make sure and select the bigmem option in semaphore manager and reboot for settings to take effect. Then you have 403MB RAM.

hello
so here.my friend has samsung galaxy s I9000,and he gave it to me to flash it.now, wont have problems with flashing since im experienced in odin and cwm,but i would need someone to tell me wich kernels and roms should i use.
what i need:best gingerbread kernels,and best ics kernels.ill try many roms in this two days i would have this phone,but my only concern is the kernels.
i am also thinking about to make MegaBassBeats for GS gingerbread users.but i would need your help then.thanks
All ics kernels are great, midnight, semaphore, devil and glitch. Personally I find midnight and semaphore most stable.

Try slim ics, doc master with glitch or devil kernel

ICS is stable and by far superior, slim ICS with devil or midnight kernel. Anyone would love that combo.

Hi!
How do I update SlimICS with Semaphore kernel installed (the current versions when new SlimICS version is out)?
Just clean /cache and Dalivic?
Clean something else?
Then install the SlimICS components in CWM?
Do i have a "clean" SlimICS after that without semaphore components left?
And then optionally reinstall semaphore kernel?
Another question: When i want to test Semaphore kernel.... how can i completly uninstall the kernel after testing?
THX!
Mart
Before updating I always revert all semaphore settings to stock, in recovery wipe cache and dalvik, clear init.d and ns tools then follow update changelog instructions.
If you want to revert back to stock kernel after a play with semaphore, the kernel is provided over at the slim website, check the version though.

I recently instaled CM9 4.0.4 on my i9000 and the battery life sucks. I want to flash Semaphore kernel, but i need some advices ..like what version should i flash etc.
Can someone help me ?
EDIT: I tried to flash 2.7.4 version + .pit file but after that i get boot loop. I've flashed again 2.3.3 and then CM9 4.0.4 ..

Flash a Semaphore kernel designed for ics. See http://www.semaphore.gr/homepage/semaphore-ics which also has links to xda-developers.

I downloaded Semaphore_ICS_1.3.0. That's all i need, right ?
Just choose this file on PDA and flash ?
EDIT: I already did that and worked.
Only 1 thing: after flashing, i had to push the power button to start ... didn't had to reboot after flash ?

Semaphore 1.3.0 is the one you need. You can flash it through Clockworkmod recovery, its the easiest way. Don't forget to wipe cache and dalvyk cache before flashing a new kernel. Besides semaphore you could also try devils kernel 1.0.3. It is more performance oriented. Flash the one you like. The only thing I don't like about semaphore 1.3.0 is that wifi tethering doesn't work.
Reboot after flashing is crucial, but if you have the new semaphore configuration app, you did it right! Just reboot one more time to be sure everything works alright.

but i have a problem, my phone sometime reboot and i can't discover the cause of this.
i try to uninstall my apps one by one but with no positive results.
i thought the problem was the CM10.1 because is a nightly rom, so i've installed the stable version of CM10 but the problem appears again.
so now i have installed again the CM10.1 .

Which kernel you are using?
you may try this,
1) reflash the rom with full wipe.
2) if you are overclock the OC clear int.d and NStool setting or using kernel cleaning script
note: only use one kernel setting apps ( e.g NStool , semaphore manager and +++)
If you are using semaphore kernel try not to use NStool setting and semaphore manager.
Hope this will help. :fingers-crossed:

i think the problem is the app of the sim card, because sometime it disappear from the drawer. This app is named "kit strumenti sim" (in italian) and is a default app...
I kinda have a similar problem with the OP. Except, my SGS (running CM10.1) only random reboots if I'm using another kernel, other than stock (mostly, I tried with Semaphore, diff builds). Any ideas anyone?
I would really like to use Semaphore, due to its deep idle and other options.
Sorry if I off-topic'ed here!

if you flash semaphore kernel(2.9.++ is for 4.2.++ ROM) and reflash the cm10.1 rom yor kernel will change to cm10.1 stock kernel.
so the step should be flash the rom and reboot to recovery and flash the kernel you like. for me flash a new kernel i will clear the NStools settings and init.d directory from advanced clear before i flash any new kernel.
