So I understand the i897 roms have to have i897 modems and vice versa with i9000. I've been searching for about an hour, but can only find that same answer I already just posted. My question is, can you use an i9000 kernel with an i897 rom? Since its an i897 rom, I would need to keep an i897 modem correct? Or would I use an i9000 modem due to the kernel. The reason I am asking is I would like to OC/UV. I liked the speed I got from Firefly, but not the battery life. So I went back to stock Froyo. I'm just going to stick with stock, root, remove bloatware, OC, and call it good. I just use it to play with when I'm bored in class and text/call, and stock does that just fine for me. Just want OC. TIA.
There are Froyo I897 kernels that support OC/UV, BLN, Voodoo, etc. I believe froyo is less picky and it is possible to mix and match i897 roms with i9000 kernels but that is not possible on GB. But as I said before you can use a I897 kernel if you just want OC/UV. (good kernel is Design Gear's Cognition 4.x.x kernel)
And since u r gonna use an i9000 kernel, u need to use an i9000 modem to avoid problems.
Kernel and modem need to be paired--i897 with i897 -- i9000 with i9000... (in order to not have issues)

what would be the best kernal and modem combo for this rom i really want good battery life I just got my captivate 6 days ago and out of 3 roms i like this one just want to know the best choices.
Speedmod k12t kernel and KP1 modem.
Take a look at my signature, results speak!!
Nothing against what any particular person will state or tell you to use, not all combination's will necessarily have the same effect from phone to phone. This is really the same as which ROM is the best because what works well on phone "A" might not work the same as phone "B". Just try different combos to find what your phone likes because these phones are very finicky.
i've been reading and this is what i come up with looking at the rom i flashed this is what is says.
model #sgh-i897
firmware 2.2
baseband i9000ugjk3
kernal version 2.6.32.9
build # gingerr5
off this info which kernal would i flash the one for captvate or the one for galaxy s i9000.i just dont want to do something stupid sorry for the questions.
You would flash an sgh-i897 kernel.
Here's a link to hardcore's kernel, http://forum.xda-developers.com/showthread.php?t=893880.
you can use sgs kernel flasher to install it.
The link is at the bottom of the original post in the attached files box
not to ask more ? but is that because my phone is still based on captivate but with just a base rom.and what is really a base rom 2.2 mod to work on captivate?
Yes, the captivate sgh-i897 doesn't have 2.2 froyo yet, because it hasn't been released yet, but developers used the leaked version of froyo to base their roms off of. An i9000 rom is actually a rom from an i9000 galaxy s phone that was adapted for the captivate. But basically, all you have to worry about is whether or not the numbers match up.
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.

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

Kernels have to match modems. kb1 to kb1, i9000 to i9000.
So is running a i9000 kernal better than using a captivate kernal?
if so what are the pros and cons if any?
rom kernal match
Look. I've tried different kernals with stock froyo 2.2 and learned the hard way with sticking with stock modem. Call quality was crap and battery life severly dimished with having a improper mix of modems and kernals. Since those mistakes I run continuum 4 with onix kernal 2.05 and jvk modem and have great batt life and call quality and download speeds are phenomenal. The best way I have found without going flash crazy is to see what the experienced people are using on their phones. The have it listed in their stats at the bottom of each posting they make. These people have been modding for awhile and know by experience what works best. Try that and you should have no problems getting the best combo for your captivate. Hope this answers your question. Good luck!
hsupa is over rated the phone already has hsdpa. hsupa may be good if you want to video chat or teather. but if you must get hspa in full you want to flash a different rom. no one has figured out a workaround for the brokn bluetooth calling with a rom/modem mismatch on a north american captivate rom.
as for the kernel, well i haven't tried an i9000 or i9010 or i9088 kernel on kb1 but they all should work. also i haven't tried changing the modem without changing the kernel but i believe that should also work. even if it is not recomended. i have never adhered to the notion that modems and kernels should match and had good luck with modems for t959d i9000m and i9088 on i9000 i9010 and i9088 kernels without major problems. it does seem that the older modems do not work all that great on the captivate with call volume or quality problems regardless of rom and kernel. but the kp1 from i9088 and kc1 from i9000 are both great on the captivate, i think i give kc1 the edge. if it weren't for those two and maybe others that i didn't try i would recomend leaving it all kb1 for the simple fact that a phone should make good phone calls.
the adage that the modem and kernel must match is true. ie. i9000 kernel/i9000 modem i897 kernel/i897 modem....it is absolutely true you must match those. if you use an i897 modem with an i9000 kernel or vice versa, you will have data but no voice. its not just a myth

This actually seems logically possible.
If we can use a reoriented i9000 kernel + i9000 modem on a captivate rom, why can't we use a matching captivate modem+ kernel on an i9000 rom?
I thought the important thing is to match the modem and kernel...

You're right. As long as they match it's fine.

Well, accidentally I ended with this configuration:
ROM: Apex 9.2 (JVR)
KERNEL: Talon 4.4.22 (JVR)
MODEM: KH3
Teoretically this shouldnt be happening but everything seems to be working O.K. No Force Closes, WCDMA 850, average battery life, WiFi, etc.

you have always been able to run mix/match, until you need to make an actual phone call. no voice.

Yes I ran that combo until I got a phone call and the other person could not hear me and the volume was cutting in and out flashed back to JL2 all is good again
Running Dlevs 5.0, and latest talon kernel, modem JL2
As you can see from my signature I am still running 2.2 ROMs. I just prefer the stability, and have zero issues with both that I am using now on different captivates. One of them, Continuum 4.1 is and i9000 rom, using Onyx kernel with jk4, the other is the i897 Cognition, cog kernel, kb1.
I think, based on what I am reading here, I will try to intall the i897 modem and kernel on the Continuum 4.1 ROM. I really like this ROM but REALLY prefer the sound quality of the i897 roms because of the Audience chip.
I will experiment this weekend and report back. As of now, I prefer not to do this kind of experimentation with the GB roms. Anyone else interested in seeing how this turns out?

Hi Jack man,
if you are still considering flashing i897 kernel & modem , my captivate is still Froyo 2.2 stock (rooted), with the uckb2 modem and kernel 2.6.32.9. I already have a dump of the kernel (I checked is working) and could send you a dump of the uckb2 modem (unchecked, I'm unsure about flashing this one back, since I have the 100% battery shutdown issue and still considering a RMA) if you are willing to try.
Let me know,
Angel
Well, I experimented. Here's what I used and how it went.
I installed Continuum 4.1 (a froyo 2.2 rom) then flashed the Exist kb1 kernel along with the kb1 modem. I thought everything was going to be fine. Calls worked fine, data seemed ok but slower than I was expecting, but when I went to turn on wifi if just didn't work. I made sure it was't the router - my wife's phone was working fine on the router, along with a laptop on it.
it would also not connect to the neighbor's router either. Flashed back to Cog4.5.3 - wifi worked fine.
Too bad, because I really like the small features of Continuum 4.1
If anyone has any ideas to fix the wifi in this setup let me know. I would love to keep it.
I'm considering switching to ICS, but I'm wondering is there an ICS kernel that is based on I9000 sources? Like how we have JVU, JW1, etc. I9000 kernels? It seems that the most popular is Glitch, but Glitch is I897.
I also need a modem for ICS that doesn't give me the roaming message since I'm on Fido. Since modem works with the kernel, this means that if there are no I9000 based ICS kernels, then I can't use a I9000 modem.
glitch (and all cm kernels) are reoriented from the I9000 to work properly with the I897, they aren't based off of captivate anything, so you HAVE to use an I9000 modem, if you look all the modems posted in an aosp format are I9000
I'm on glitch with jk4
And also your phone wouldn't work quite normally if you flashed a real i9000 kernel
