[Q] Replace Kernel in Cognition v2.3b8?

Hi Guys,
I just got my Captivate couple days ago. I were able to unlock, root, get a new ROM (Cognition v2.3b8) and install some apps. I'm looking to get a new kernel for the ROM. How would I go about flashing it to a different Kernel like SpeedMod K12I ? Thanks.

Sgs kernel flasher app in market
To be safe always disable lagfix prior. App is very easy to user and quick

I am a noob here. But I am wondering what are/is the benefits/risk of replacing the kernel that comes with Cog v2.3b8 with another. I recently flashed Cog v2.3b8 from stock (batch 1006), and find this is pretty much as stable as stock. Only issue is with GPS (which was hit and miss on stock). So do the benefits of replacing the kernel in Cog v2.3b8 outweigh the risks?

Well kernels have different features and abilities in them. It depends what you want from your kernel. Some might support BLN while others will have OC/UC or just OC. Various combinations of options. You just need to make sure that the kernel/ROM/modem are from the same family, etc. I9000 or Captivate. If you flash a i9000 kernel into a Captivate ROM you might have issues.
Cog v2.3b8 is a Captivate ROM I believe. You can flash Kernels which are for it.

cog runs fine with an i9000 kernel so long as you also use an i9000 modem. i can't run the i9000 roms because of service drops but this set-up is still very good.

If you want to install a new kernel over the existing kernel,
1. Download the Kernel from http://forum.xda-developers.com/showthread.php?t=893880
2. Go to CWM recovery. (directly or through ROM Manager)
3. Choose the zip from SD
4. Flash and Reboot.
Make sure that there is atleast one boot after the ROM is installed.
To confirm,
check Kernel Version in Settings-> About Phone
You should see something like

Well each kernel has it's own benefits.
For instance, Speedmod uses sztupy's Universal Lagfix unlike other Kernels that use Vodoo Lagfix.
The main differences would be in the speed and battery. Samsung uses 250hz (as default), firebird kernel uses 300Hz and Speedmod uses 500Hz. Doesn't change battery consumption much but provides more smoothness.
Then the RAM Available. It varies from Kernel to Kernel from 300-350MB.
Cappy Kernels are for Captivate Only because of reorientation fixes and button mapping.
Hope this helps

[Q] Best oc/uv kernel

So I used to use the super optimized kernel for it's oc abilities, but since I've flashed darky 9.4 I can't use it anymore for some reason, so does anyone know another kernel to use?

Have you tried DamianGTO's Kernel? I do love this kernel. Although I'm on Doc's ROM, I think it may work on Darky's 9.4, since it's also based on JS8. It has both Odin and CWM flavors.
Have a look here: http://forum.xda-developers.com/showthread.php?t=959696

[Q] New Firmware, ROM?

Hi...
I've only made a couple posts on the forum...
Updated my phone a while ago using the xda developers and had great success but reading through the lastest posts, im a bit confused and lost as to the best available updates...
I'm currently running an update from keis...
Firmware 2.3.3
Baseband I9000XXJVO
kernel 2.6.35.7-I9000XXJVO-CL82937
build Gingerbread.XXJVO
My main desires would be a new rom with root, a lagfix (there are so many?) and a battery lifes mod of some sort (never used these...)...
Has anyone got any advise / recomdendations??
I'm a bit of a lamen, and no programmer, but I'm confident to flash and use odin etc....
Thanks in advance

i recommend juwe's smart edition 5.3, it has ram script,excellent battery life. it is a complete rom. if you have any other questions post them on my thread "Ask me anything, i have the answer" ,it should among the top

Jetpack is new, clean, professional, fast, smooth and battery efficient so if you want try it!
Sent from my sgs
kernel: galaxian
Rom: jetpack

Darky's 10.2 extreme edition with darkcore kernel and voodoo sound and lag fix. Full flash tutorial is on the darky thread, fast stable and decent battery life. Everybody had their own personal favourites, read up on the roms and pick what suits you best. This is on a gb 2.3.4 base

You can use Martux rom.
Its a good one for starters. Download base JVR from here - Matroux Rom Flash it via Odin. Clear instructions are given there.Then flash any JVR kernel preferably semaphore 1.5 via odin. Then copy Martux Rom to ur sd card and flash via CWM.

It's only about what you prefer.
Myself am flashing a new ROM each day just to try them out.
I think I'll keep Hybrid.

[Q] New on android and I had problems with kernel talondev

Hi all,
I'm new to android and some things I do not understand, for example I have the galaxy captivate with the following characteristic:
Rom Android 2.3.4 I897UCKH3
boog_kh3_kernel3
su-2.3.2-efgh-bin-signed.zip
I updated my cellphone using these files, and all works fine but I wanted install a new kernel the last talondev, but after install it I think that my sgs is on soft bricked, displays the logo of AT & T and then starts "loading talon...", but then restarts.
This kernel can be used with the rom? it is compatible? or What should I do to choose a kernel?
Best regards

Talon is I9000 port kernel you are using native I897 rom. Use Samurai, Corn kernel or Boog's kernel. Actually Im not sure there is a corn or samurai kernel for KH3. I know they have it for KJ roms.

I have to find kernels for KH3, right?
Thanks

Correct. Or update to a newer leak like KJ3 as a example.

And I can change to a custom rom? or that such the cm7 rom?
I talk to do this to exit the soft brick and have it back.
thanks

CM7 has its own special instructions. I haven't kept up with it so go to their thread and read. But ya you can change to custom roms like Fusion IX, Fasty and others that are based of a newer firmware version.

You need to flash back to boog kernel. If this does not work it is best you re-flash to stock KH3 with the one-click solution here. http://forum.xda-developers.com/showthread.php?t=1300843
Choose the one WITHOUT bootloaders since you already have those on the phone. It is safer that way.
Regarding CM7 ROMs. You must know they are completely different system compared to the normal Captivate ROMs. Read this thread before flashing:
http://forum.xda-developers.com/showthread.php?t=978150
Don't get me wrong. THEY ARE VERY GOOD CUSTOM ROMs...absolutely. But you cannot mix and match.....Follow CM7 instructions strictly.

thanks for the replies, I will be reading information about their opinions.
thank you very much , I'll let you know the results.

I am not amused by your phones performance

[Q] Which rom should i use?

What rom is best and most stable?

JVT stock rom with the semaphore kernel.
or wait for the F1 Innovation ROM Version 15 which is gonna be released tomorrow:
http://forum.xda-developers.com/showthread.php?t=1058814

thanks for the reply ill wait for the f1 and see

ICS 4.0.3 rc2.1 onecosmic
ICS 4.0.3 rc2.1 onecosmic
love these rom

ICS from onecosmic ist really cool, but think about the problems.
Some Apps dont run with this rom. For me, there ist no connection with MyPhoneExplorer. Also problems with unsing external SD, because it is rooted to mnt/emmc.
After flashing GOA 6.0 and some other custom roms, i am at the moment on doctorz rom 13.1 with no FCs or any other problems. It ist smooth, all apps are running..for me the best rom at the moment.

First thing you should decide if you want a 2.3.x ROM or a 4.0.x release. Then you can decide which ROM is right for you.
Check the screenshots and see what you like the most. I can advice MintBerry which is very fast and good looking, but since it's not based on a Samsung ROM you're gonna miss the Samsung Apps (as far as you can miss them).

Stable - any stock ROM or Stock Rom based; you can speed it up by using a different kernel (try semaphore) and/or tweaks (Thunderbolt's). I don's advise any ICS based ROM: they are still a little away from what I call ''stable''.
As for best... well, it depends on what you think. My advice is to try several ones. Each user has it's thoughts on what they think it's ''best''.

i want 2.3.x because i know ics isnt that stable and alot of things dont work still..
currently im on jvq 2.3.4 flashed with odin ( i don't have cwm because i dont know if it will void my guarantee :/ )
and a user above suggested jvt but i also saw jvz and im wondering which is better ( both 2.3.6 )

I have tried lots of roms, I found galaxydroid 3.3 gave best battery life, but 5.0 lost it. I am currently using mitrerom, and this seems very stable, nice tweaks, boots very fast and thus far have no issues. I am avoiding any 4.0 rom, as they are still all in beta stages and can still have issues. Best thing to do, is see what you like and flash, flash and flash. You cant do any wrong if you read the tutorials and take your time, oh and dont touch the bootloader!!

Buttwad. Why not to post a link to that "mitrerom"? I can't find it anywhere.

can someone post a download link for odin please ?
i cant find it anywhere

GingerReal2 R2.0.0 + Semaphore 2.4.0 i the best

Myhm... someone can.... first post here...

if i want to flash semaphore with odin i put it in the pda ?
it wont break stock jvz?

ANY kernel in Odin -passes as PDA.

JW1 with CWM-Kernel or SauRom ....

so stock jvz will work fine with semaphore 2.4?

bump :/ this is my last question
