[Q] Kernel compatibility

Hi,
Can I flash a froyo kernel to an eclair rom and vice-versa?
Will I loose/get fonctionalities?
What I want to do:
flash a 2.6.29 kernel(eclair) to a JPK rom to run voodoo on JPK (I will propably loose some fonctionality since its an *old* kernel)
flash a 2.6.32.9 rev6 (asian froyo dxJP1 kernel) to a JPK rom (to get better battery life and smoother flash since I tried JP1 for a week and it was stable and fast)
flash a voodoo modified kernel to any 2.2 rom to see what happens (but I am a little afraid to flash an oc/uv kernel to a rom not designed for it since it could maybe, under some circumstance damage the phone...)
Any ideas or tests already run?
I am gonna try the JP1 kernel on then JPK rom tomorrow to see if it works and if I got improvements from the JP1...

And you will get a nice paperweight instead of your phone.

Pretty sure that won't work but if you have 3 button rec you should be fine.

I got the 3 button combo (thanks to richthofen and dadonali and others) so if the kernel is not supported I can flash back my original kernel?

Your Phone wont boot, but try it.
2.1 and 2.2 are different worlds.

franklin01, this thread belongs in the Q&A section, not in development. Take a moment and read the "STOP!! Before you post, read this NOW!!" thread at the top of both of these sections, it has clear guidelines for proper thread placement.

[Q] Kernel / Wolfson DAC: not sure what to do

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.

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

Need some clarification please

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.

SpeedMod Kernel with Gingerbread

Hi Guys
I am upgrading to a SGS i9000. Previously had a Motorola Milestone, custom kernel is new to me.
I've been searching and couldn't find anything. I want to load gingerbread XXJVK and use SpeedMod Kernel. Will this cause any problems? If I do experience problems would it be straight forward to go back to stock kernel?

Speedmod is a kernel designed to run with Froyo, not Gingerbread. Many custom 2.3.3 ROMs have you install Speedmod as an intermediary step just to get CWM installed, but it will not work with JVK. You will need to install one of the kernels specifically designed to support JVK.
I STRONGLY suggest you read the many threads posted here about JVK and the process of flashing to it, AFTER you have read the stickies about flashing ROMs on the i9000. Foreknowledge is always better than Support Calls.

Thanks for the advice. I keep going back to the stickies about flashing ROMs to i9000. I guess I will keep reading.

I would wait for the release of Gingerbread . Once its released the devs are going to have a more complete set up to work with .
jje

There's no source to work from... so there's no speedmod as of now. Your best shot could be supercurio's hacked JVK kernel which can convert partitions to ext4. But remember, the rom is still a beta.

My SGS came today. I'm going to look at flashing darky's rom tonight.
I have Cyanogenmod7 RC3 on my milestone at the moment but I don't think I'll miss the 2.3 features.
Again thanks everyone for the advice

hi guys,
i'm a noob.
need some help over here.
i'm using galaxy S i9000.
i rooted my device with speedmod kernel k13e-500hz #36 but firmware is v2.2.
is theer anyway to upgarde to v2.3 with rooted kernel??
many thanks

[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.
