Hi there , I just need some info about some stuff about ROMs, kernels and modems.
I plan to flash the latest firefly ROM on my rogers Captivate (SGH-i896) and need a but of clearing up. Some question will be thrown your way
1- if I do flash the ROM, what and modem gets flashed with it? Or do I have to flash them separately?
2- whats the difference between speedmod and suckerpunch #59?
3-Is the lagfix included in the ROM or kernel (if it gets flashed with the ROM)?
4- what the heck is vodoo?
Thanks guys ....I did a lot of reading on different threads and somethings are worded differently and confuses me .

1. The ROM includes the modem so there's no need to flash one separately. And if I remember right, Firefly uses the JK4 Modem.
2. Suckerpunch includes the ability to overclock and/or undervolt which affects battery life and overall performance. I personally use speedmod because that's what was included with my ROM and I haven't decided to flash a new kernel.
3. Yes, the lagfix is included in the ROM and the kernel is (if I'm not mistaken) what controls the lagfix.
4. Voodoo is another set of custom tweaks and enhancements that improve a number of things including speed, audio, and video.
Hope that answers your question.

Hi,
for what reason do I a kernel flash? Are the rom included kernels better then a lonestanding once? can I flash any kernal to any rom?
what is the benifit of flashing an other kernel then the once ued in the rom?
thanks
When you change the kernel you choose a better kernel then stock.
They are more tweaked and habeas more support fir different things.
**Using my own JPX kernel, z4mod, 345MB Ram and ext2 filesystem**
- Different file system (better battery life) (I'm still experimenting with finding the right one)
- Access to the kernel allows you to use the led backlights on the buttons for notifications.
Those are currently the main reasons why I flash diff kernels.
You can have direct acces to one of the most advance lag fixes around(voodoo) better performance ,overclocking ,color correction for ur display,more user accessable ram and so on

Good question.
Samsung open-sources their released ROMs from time to time and many of the "kernel-hackers" (I'd call them plain hackers, what's with the prefix?) here utilize it to add/provide features and fix bugs (bugs are overlooked by people, its normal).
For instance, SpeedMods' kernel provides an Overclocking support for your Phone's CPU, if you want that extra juice. Likewise, Voodoo provides a set of visual enhancements among other things.
HTH
Another important reason is to regain 2e recovery if you lost it after flashing a stock firmware. This assumes the kernel you choose includes this feature
Fine, thank you all!
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?
Thankshttp://media.xda-developers.com/images/icons/icon7.gif
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

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
i'm still relatively new to the whole rooting experience
about a month and a half ago i picked up a captivate..since then i have rooted..upgraded to 2.2..and flashed cognition v3.02 rom
everything works great..but now i'm interested in flashing a new kernel (still running stock captivate kernel) and overclocking to 1.2ghz to add a bit more speed
in my settings i can tell you this..baseband version is I896UXJL1, kernel version is 2.6.32.9
from what i've read your modem version matters when flashing new kernels
i also understand that odin is used to flash kernels and such..but i have no idea how to use the program and all i can find on google are methods to revert back to stock firmware
do i need to upgrade my modem?
what would be a stable kernel that allows overclocking that you would recommend?
how do i use odin to flash that kernel?
i don't really want to do anything without full knowledge so i can reduce the risk of bricking my phone
i would greatly appreciate any help and i fully support the amazing things you guys are doing with the android platform

jl1 is your modem version right now. if everything works for you, why you want to change?
suckerpuch is a kernel allows oc and it has a CWM version to flash.
oc usually will shorten your battery for the daily usage.
The easiest why I found to flash kernal is to use SGS kernal flasher you find it on the market lets you flash different kernals from within android. Once you get a different kernal with cwm you cab just flash modems from within the recovery menu as long as the modem is in a cwm flashable file

I have installed COG 3.03 and find it great.
I want to unleash the power of the Wolfson DAC , and for that it seems I need a compatible kernel.When I installed the Voodoo App I got the message to do so.
Now I have search many, many, many threads, and I am MORE confused if anything; can someone point me towards the correct (and clear! 100 pages long threads make it very confusing to see what is the consensus) info for the following questions:
Which kernel should I choose?
How do I install it?
Do I HAVE to change my modem if I change the kernel?
Will the kernel swap have any incidence on future ROM choice I might do?
Will changing the kernel do anything to my reception (which is super great)?
Any help is appreciated; again, I tried understanding what to do by myself like a big boy, but I got to read so many threads in some many directions, that I can't make a clear choice....

Hmmm, isn't this what Supercurio is doing with his kernel drivers? Some kernels in here already have supercurio's code in, and you also need to use the app he made.
I think almost all recent kernels support it. If it says supports voodoo sound there you go. Try hardcores kernel.
Sent from my SAMSUNG-SGH-I897 using XDA App
Supercurio's audio thread has a link to all the kernels with Voodoo Sound. You can also just look for the phrase "Voodoo sound" in the short description.
Unfortunately, AFAIK every Voodoo sound kernel for Captivate is i9000/i9010-based, which means you'll have to switch modems (and lose bluetooth calls, unless you also switch to a different ROM) as well.
I'm sort of amazed no one put this and BLN into the native-Captivate Rogers Froyo source yet. DG said he had a test version of this combo *weeks* ago, but no release thread. And somehow no other kernel devs are interested...
Oh yeah, someone will kill this thread im sure cause it doesn't belong here. Should be in q and a.
Sent from my SAMSUNG-SGH-I897 using XDA App
Yeah, I see this thread being moved or locked soon.
I run Cognition 3.04 with hardcore's speedmod kernel, which has the Voodoo Sound 4 drivers in it. I use the T959D TLJL3 modem which gives me great reception and killer data speeds.
When you flash a new ROM, you'll probably be wiping and reinstalling everything anyway, so chances are you would have to flash whatever kernel/modem flavor you choose again anyway.
So:
Which kernel should I choose?
Any REORIENTED i9000 kernel with Voodoo Sound 4 will do.
How do I install it?
Most of them have the option to use either Odin or Clockworkmod Recovery. Since you're already using Cognition, make sure the Clockworkmod Recovery that you use has RED FONT. If you're installing the speedmod kernel it will be GREEN FONT thereafter.
Do I HAVE to change my modem if I change the kernel?
Since you're probably going to be flashing a reoriented i9000 kernel, i9000 modems will work best. I've had no problem running the JJ4 Captivate modem, but others have. Also, like I said above, the T959D TLJL3 modem is great.
Will the kernel swap have any incidence on future ROM choice I might do?
See above.
Will changing the kernel do anything to my reception (which is super great)?
This is certainly more affected by your modem than your kernel. I haven't seen kernels have any great effect on this.
HOWEVER, it's worth mentioning that i9000 kernels will chew up more battery than Captivate ones. Don't count on more than 20 hours of battery life... if you can even get that on a stock phone, LOL.
To flash a new kernal you can either use CWR or SGS kernal flasher from the market to install it. You do not have to change the modem when you change the kernal and when it comes to picking one that will work with voodoo you can usuall find that out in the original post.

I am using cog 3.04 with the firebird 2 ver1 and jk4 modem to use voodoo control. I flash back to stock cog.3.04 kernel & modem when I want to use bluetooth. Speed mod kernel caused my phone issues. Seems to be trial and error with each phone, good luck with your set up
Hey everyone, just a general question about flashing i9000 ROMs. Obviously they have quite a selection over there, and I was just wondering how one would go about porting and flashing them?
You'll need a reoriented kernel. Not too hard to come by, look for exaliburinhand's threads in captivate development
Sent from my SGH-I897 using XDA App
What if I'm flashing a 2.2 ROM? I don't want to mess with Gingerbread at the moment.
Xcal also has a reoriented kernel for 2.2. You can dl out from dev thread, or from SGS TOOLS (kernels are under rom tools).
Awesome. How would I use the reoriented kernel with the i9000 ROM? Just flash through CWM? And what if I want to flash a different kernel? (Onix, SpeedMod, etc...)
Put the redbend_ua and zImage files from the kernel in the updates folder of the rom zip. Overwriting the others. And flash the whole rom in cwm. One stop shopping.
I was thinking SGS Kernel Flasher (which I've used several times with good results).

extra step thats not needed if you know what kernel/modem you want to use in place of whats in the rom zip
Ok, so can someone take me through flashing an i9000 ROM in semi-noob terms?
