[Q] Kernels and Modems - Captivate Q&A, Help & Troubleshooting

I am in the process of developing a ROM, and I would like to know what kernel options I have if I am using a 2.3.5 Gingerbread (JVT) based ROM

If you're building a ROM you should know what you're doing, including what is compatible with what base your building from...
Kernels (in no particular order):
Xcal
Talon
Darkcore
Sephamore
Any I9000 modem will work, jk4 is the "go to" as it seems to work the best for the most users.
now, go play and enjoy your bootloop

Thank you, I just had some confusion with which kernels and modems were compatible with each other.
I will enjoy every bootloop until my ROM is done!

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 .

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,

[Q] Flashing/Porting i9000 ROMs

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?

[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.

Why would you send him to the nightly page and not the 7.1 stable current nightlys are a bit broken.
I am not amused by your phones performance

[Q] Which kernel for Galaxy S?

Hi there,
I'm using CM7 on my Galaxy S with kernel 2.6.35.12-gdf10700 [email protected]#1
Can anyone please tell me if this is the "recommended" kernel for CM7?
I've read that Hardcore Speedmod kernel is meant to be the "best" but is that still the case?
Can I use any of Hardcore's latest ones listed here:
http://forum.xda-developers.com/showthread.php?t=1044519
http://touristinparadise.blogspot.com/2011/10/samsung-galaxy-s-download-speedmod.html
because apparently they are not to be used with CyanogenMod?
Many thanks
Stock kernel is the best if you want to avoid bugs.
Do NOT flash any other kernels than those which are made for CM/MIUI.
Here are few:
Glitch: http://forum.xda-developers.com/showthread.php?t=1041532
Fugu: http://forum.xda-developers.com/showthread.php?t=1112568
Zach's kernels: http://forum.xda-developers.com/showthread.php?t=1053304
You can try those, but for me stock is the best.
Many thanks.
I was just a little confused because Cyanogen's own wiki suggests using the Speedmod kernel:
http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S:_Full_Update_Guide
so I wasn't sure whether stock kernels are compatible with CM7.
So... the stock kernels (http://samsung-updates.com/rooted-stock-kernels-for-samsung-roms/) are fully compatible with CM7 then?
Thanks
It says flash speedmod because by flashing that you'll get CWM which you need to flash CM.
And no, do not use those kernels. Those are for STOCK ROMs.
When we said "stock", we meant the kernel that is included by the CM already.
Go to developement section and find topic with [Kernel][CM/MIUI] or something like that. Those are compatible with CM.
Just check links I gave you.

Got it, thanks - when you said "stock" I thought you meant the ones from Samsung directly.
In that case, I'll just stick with what CM includes and I won't mess around with them.
Thanks.

Just hit "thanks" button if I helped.
I add that to my sig.

Best choice Samsung Galaxy S I9000 CM 10.1 + Kernel + Modem

Hi everyone!
I installed last nightly build of CM 10.1 (31/03/2013) on my Samsung Galaxy S I9000.
I also use the standard kernel that comes with CM distribution and Semaphore's ClockworkMod Recovery 2.7.4
Everything is working great, my old phone is reborn! Except for the excessive battery drain...
I read that to solve that problem one possibility is to flash a different kernel (such as Semaphore's one or Devil's one) and to change the modem. Anyway answers on the web are neither organic nor clear.
According to you:
- which is the best kernel to use in order to solve the battery drain problem? (please give me the exact version)
- which modem should i install? and where do i find it?
- [noob question] if I flash a different kernel and then i upgrade to a new nightly build do I have to flash the different kernel again? I mean, if I upgrade to a new CM release my kernel is replaced?
Thanks a lot for your precious tips!
currently I'm using this http://forum.xda-developers.com/showthread.php?t=2024269 with the updated 4.2 devil kernel, quite fast, not having much luck with the modem though as the supplied one didn't seem to work, flashed a few from this thread http://forum.xda-developers.com/showthread.php?p=30588173&highlight=nz#post30588173 and finally got signal, but I'm unsure if these were meant to work with cm10.1 or not as it was an older thread for cm7/9 etc.. and I can't seem to find any info on cm10.1 modems specific to NZ
as for your kernel question; it kinda depends on the ROM, if it's an update then you will keep the kernel you had earlier, but new ROMs usually come with their own, I like to try out a few different ones and decide for myself what works for me, just make sure your kernel is made for the android version of your ROM, eg: there are devil kernels for 4.1.2 that will not work on 4.2.2, you need the 4.2 specific, also applies when flashing gapps..
Mackay and Infamous are really great and smooth. The built in kernel is very good. Set deep idle on but there is not much difference between cm10.1 kernel.
