What is the benefit if any of moving to the new Gingerbread roms over the CM7 that I am currently using?
I am pretty happy with CM7. It seems like everyone is pretty excited about them, but doesn't CM7 offer the same 2.3.3 with a bunch more niceties?
better battery life, better camera, and (probably) more efficient USB sharing to PC
BUT there are caveats at this point in time
1) no reoriented kernel (yet)
2) no clockwork mod recovery (yet)
3) ugly distortion on boot unless you flash new bootloaders (never a fun thing to do as it could brick)
What is a reoriented kernel? Does it have to do with the orientation of the screen?

Yes. Kernels from the I9000 rotate the screen 90° (among other things) when on a captivate reoriented kernels have been fixed so this doesn't happen.

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 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
I have been using I9000 rom with speedmod kernel and 850 modem for i897 device for a long time.
I installed different kind of i9000's Captivate kernel. None of the i9000 kernel's Captivate work on Tango and Fring video chat. I always get black screen on Tango video chat and Fring always crash when video turn on.
I tested on i9000 rom with Cognition 4.3's kernel and I897UCKB1 modem. The video chat work, but this I897UCKB1 modem is horrible download and upload speed while using video chat. That's why I didn't like to use I897UCKB1 rom because the 3G speed limited by AT&T. If I use any i9000's modem with Cognition 4.3's kernel, the voice call will not work.
I think i9000 kernel for Captivate must disable or remove front face camera function in order to work on Tango or Fring video calling.
Anyone know how to fix this?
Captivates have no front facing camera.
That's why need to disable front face camera on the i9000 kernel's Captivate.
And Cognition 4.3's kernel able to use video calling, but not on any i9000 kernel's Captivate.
They gave a proximity sensor and a light censor on the front that is often mistaken for a camera. As for moderns and kernels, I would recommend reading the modem thread. It will put you on the right path.

I'm pretty sure the op knows there isn't a forward facing camera, what he is saying is that the video chat works on kb1 but not on i9000, like the i9000 kernel makes the app look for a forward facing camera and then it doesn't find it and crashes or shows a black screen due to no camera. He wants the kernel to have the app go to the rear camera like it should. Right?
I knew Captivate never have front face camera since I have this phone.
The only problem i9000 kernel still contain front face camera code.
The Cognition 4.3's kernel seen like wasn't or because it is base on Captivate rom.
Either modify or disable front face camera code inside i9000 kernel or use Cognition 4.3's kernel with hsupa enable modem.

My apologies. I misunderstood.
Have you tried using the kb1 roms (cognition, fusion, torch ) with existz kb1 kernel? As far as modems, there are only 3 I think for kb1 roms (KB1,JJ4 AND JI6). If the modem doesn't match rom and kernel, weird things happen (no bluetooth, no call volume, static). I hope this helps a little, eden if it doesn't solve your problem.

All are Captivate modem (KB1, JJ4, and JI6) worked with KB1 rom except I don't have HSUPA speed which is I don't want to use AT&T modem.
i9000 rom + i9000 kernel for Captivate + i9000 modem: need to fix kernel only use back camera
i9000 rom + Captivate kernel + Captivate modem: everything work except no hsupa speed
im not sure if you will get what you want. it would require a lot of knowledge of the sources and mixing captivate and i9000 sources from a 2.2 kernel and a 2.2.1 kernel. not that it is nessessaily hard, it might be easy for an experienced dev. the devs dont really know till they try but im not sure they will mess around with it. most of the significant kernel work is being done on irc chat and in the i9000 forum, most of it is not i897 centric but latter ported to i897. it may tak a while to get something like this done and after the source for 2.3.3 is realeased im not sure that it will ever get done. problem is that noone requests it. i understand the need for hsupa in combination with video chat. without a 2 way connection hsupa is almost useless. many broadband isp's dont provide an equivilent to hsupa upload speeds. well right now atleast you need to choose between slow choppy video calls on hsdpa or no video calls at all on hspa making hspa fairly useless. what a conundrum
have you tried using a pure i9000 rom and not a captivate port? like strait out of the i9000 forum with a reorient kernel? because they may have something in the settings apk to swap the active camera for that.i dont know for sure though.
edit, forgot but you can triy the ursa minor kernel. it is the i9010 kernel but it is 2.2. there is also the i9088 2.2.1 kernels from kp2 and kp5 but it is hard to find and you might have to settle for a stock kernel in that case.

well try the andromeda rom or the ursa minor kernel from andromeda thread.
i really suggest trying andromeda if you are gonna use a 2.2 kernel. not much sense in 2.2.1 without the kernel. andromeda has some fantastic battery life for most users and alot more, i suggest changing the modem though jk4 doesn't work well for me or many other captivate users. calls suck. kp1 and kc1 are two that i can verify work well.
there may also be a kp5 dump around here somewhere with the kernel but you wont have voodoo anything. still you get a 2.2.1 kernel for the captivate with hsupa
edit: http://forum.xda-developers.com/attachment.php?attachmentid=531565&d=1299080836
this should contain a kp5 kernel with voodoo injected in. it was the origonal kernel used in dragon. dont think it has voodoo sound just lagfix
edit edit: http://forum.xda-developers.com/attachment.php?attachmentid=558036&d=1301688592 this is the ursa minor kernel for andromeda built from i9010
sources. as far as 2.2 kernels for captivate go this is the one to have! 2.2.1 may benchmark a bit better but this is a seriously fast kernel with hsupa support. use kc1 modem you will be happy.
Edit 3: I use glitterballs' kernel v.5. It is a pain in the arse but it is jpx/y 2.2.1 like the other i9000 kernels and is working for me on fring with dragon rom. I just downloaded fringe and did a test call. I can see the image from my rear camera in the lower corner. Glitterbslls really knows what he is doing. He needs to come back to the board. If you use this kernel disable all lagfix first and convert to ext4 after to include the /system partition. Also flash with neldars app. You will have problems flashing in recovery because of steam. You can also extract the zimage and .tar it for odin flashing.

we spent a long time on that rom. it started its inception in December and made its debut on XDA in January.....you will be hard pressed to find any REAL issues
if there is a rom to flash and use long term andromeda is it. i had andromeda 1.something for almost 2 months i didn't change the kernel or overclock it and i didn't even have the stock rom for that long. but switched because i was curious about the roms from the i9088. would go back but dragon keeps getting better and i want to see what dagr8 produces for the final release, he was a dev on andromeda. i think the whole andromeda team komin dev group does top notch work.
I recently flashed my Captivate (I897) to stock leaked 2.3.5 I897UCKK1
I am trying to understand what my options are for rooting to regain wifi tethering capability. Unfortunately, I really don't understand the kernel interaction and the potential compatibility issues. Normally, I understand I just need to stay on a kernel that was sourced from the same version (in this case KK1).
Anyway, I am hoping for some information on what kernels might be OK to use with my current ROM. My wish list in a kernel at this point would be BLN, EXT4 Lagfix (Voodoo or new CWM) and Root. From reading, it sounds like there is a lot more support for KK4.. Maybe I need to move to a KK4 ROM as well?
Thank in advance for not flaming the noob (I hope)

I suspect you're right. KK4 does have a good following since it is the newest leak, and there are several KK4 based ROMs out there in active development that support lagfix.
You won't find BLN on any i897 ROMs, though. There's no source code from Samsung so there is no way for the devs to add it in. For that, you would need to use an i9000 ROM or a 2.2 i897 ROM.
Thank you!

The benefits for me are the tablet mode, safe kernel, and ability to switch internal and external sd card. The rom is also much smaller. However you will not be able to run some tw based applications. You need to try it out.
Tablet Mode/UI is incredible. Safe kernel was important but since franco and speedmod came out with the workaround, they are safe. ROM size varies. Asylum is very small compared to CM9 itself and ParanoidAndroid. But they are all CM9 based.
You will NOT be able to run Samsung apps, like S Note, S Memo, S planner, anything to do with the S pen button, etc etc.
