I am new to the android world, and reading about what to do with my shiny new Galaxy.
I read about roms, JPa, JPM, JP6 and so on. What is the difference between all of these roms, and why should one use these, rather than the official Samsung versions?
Next, I read about applying cf-root kernels. What is the benefit of this?
If there is a nice peace of reading on this, I would be greatfull.
Thx.
All Rom tweak the sgs in there own way. Some don't like how sgs is and changed that.
There also custom kernels.
This is often to speed up the sgs.
They can tweak some settings or converting the filesystem to a better one.
I do preferred original firmware with a custom kernel.
I use my own kernel and use ext2 filesystem to make the phone fast.

Pretty much as DamianGto said its a personal choice i also go for stock firmware jpa in my case from samfirmware with cf root kernel. Custom kernels do various things from spead tweaks to colour adjustments. I'm running stock jpa with cf root kernel this gives you root with 2e recovery then i just used oclf from the market for the lagfix had this combo for a while and works perfect.
I would stay away from cf-root kernel. Its way to big and a bad way to root.
Oclf was good, but its an old way to lagfix. You should use a kernel isteed. Its smother and all is faster.

Thank you.
I'm not sure what is the firmware and the kernel. And not yet sure what all those different jpm, jpa, jpk, jp6 versions mean and do.
Furthermore:
I have flashed froyo, using odin, with the JPM version.
Now I found out that I have that gps problem too. The default *#*#1472365#*#* option does not work on my sgs. Any sugestion on this?
Ho.
Jpm is not the latest firmware.
In froyo you use this *#3214789650#

hello, i want to flash my sgs to froyo, i am looking in the custom roms do you guys recommend any custom roms or kernels... i dont want to use the stock ones cuz i know there is always something you dont need and you dont use...
Do you think is better to use OCLF or voodoo with ext4?
thanks!
Well its a personal taste what you use.
I only use my own kernel to speed up the system and get more memory. The rest i use mod i se and like. I have not seen any rom that have things s want.
Oclf is old and you should use kernels with lagfix.
Use ext2 if you want a fast filesystem.

Browse around in the android dev subforum, I'm using doc's rom, bunch of other people use darky's.
If you use a custom kernel, those usually have a lagfix inbuilt which you enable in the recovery menu, you don't need to use voodoo or OCLF on top of that. (Custom roms usually have custom kernels)

So which one is the latest (stable) version?
so you reckon darkys is one of the best custom roms to get? is it stable?

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
hey guys,
im using the voodoo kernel at the moment but i want to know whether the speedmod kernel is better.
what's the difference between those two ones? which is more reliable? which is the faster one?and which has a better battery life?
my second question is wheter a lagfix is still needed for the kernel. i heard the lagfix needs more battery.
ty in advice
Its a matter of personal preference.. You should try both kernels and conclude for yourselve..
but can you say something in general? there should be some differences...
ty
i'm using Stock JS3 with voodoo 5.2 and there is zero lag, and battery life is fantastic (after removing most of the samsung bloatware).
I really don't see any need for any of the extra 'fixes' the other kernals add
You can read the differences on both kernel's pages.
Which is better: apples or bananas? It's all based on opinion. Flash one, if you don't like it, flash the other.
I prefer voodoo,
At the moment im using the advanced kernel v666.2, and its bloody awesome.
Supercurio says voodoo doesnt increase battery life, so rock on!
Speedmod, whilst good as never been as smooth for me, even 500hz versions.

I think either kernal is good. Have used both and not much difference between the 2. My personal opinion- speedmod feels a little smoother than voodoo. Was using voodoo for a couple of months but now on speedmod.

One difference is voodoo is compiled by supercurio and the other by hardcore.

ty guys. i think i will stick to voodoo. actually i have the 5.2 version istalled on my gt-i9000.
but is there a thread in this forum where i can check for the latest voodoo kernel? i didn't find it...
5.2 is the latest version.. You should check project-voodoo.org for updates or folkow his voodoo sound thread
ty a lot. now i'm fine
Seems to me voodoo is bit smoother and speedmod has maybe better battery life.
You should get CWM Recovery and try for yourself since it's so easy to switch, I am on Darky's Ron and currently using Voodoo. But I was on Speedmod before 9.1 and I can't find any difference in their smoothness. The batterylife is more depending on your Rom and settings.
Happy flashing

I switched rom and kernel at the same time. So I can't fairly compare both kernels.
I appreciate Speedmod's kernel because it has tun support for Openvpn.
for me, I use speedmod as it has better battery life
I use SpeedMod, for the performance tweaks. I did briefly use supercurio's kernel, but then switched over to hardcore's, chiefly because of how it was geared at performance and efficiency, or so it said, anyway.
To the extent of my limited knowledge, I can summarise their technical advantages as follows:
Advantages of SpeedMod
Various optional performance boosts - promises battery and speed improvements, but I haven't actually done any tests for proof
Customisable lagfix - can choose from different file systems (ext2, ext3, ext4, ext4nj, rfs, jfs) and where to apply them (data, system, etc)
Advantages of Voodoo
Simplicity - lagfix (and other tweaks) automatically apply on boot, no need to ever go into recovery mode
Both have colour and sound tweaks (SpeedMod uses Voodoo Sound), and generally are very stable. You might also find less of a need to update

You don't say...
I guess voodoo is much better. I haveused both of them but speedmod has a lot of problem like screen brightness which will never be fixed! althou hardcore claims to have done so. about the battery consumption you can not say which of them is better cuz it depends on your rom. on Darky voodoo saves more and speedmod drains ur battery. that is why Darky switched to voodoo in his latest roms and if you install darky rom configurator you will see that voodoo is recommended.
I prefer the speedmod kernel because you have the choice in regards to optimizations and lagfixes. The latest kernel (k12u) really speeds up my gps fixes!!!
Stock XXPY + JPA WiFi driver, rooted, speedmod k12u 500hz
Speemod kernels are being updated almost daily,so the easiest way is to get used to using cwm recovery!
Is there a thread or site where all the different kernels are compared?
Thanks
Why don't you start one?
There are a few:
1. Hardcore's Speedmod kernel
2. Supercurio's Voodoo kernel
3. Lastufo's Super Optimized kernel (based on Speedmod)
4. Trasig's kernel (based on Voodoo)
5. DamienGto's Steam kernel (based on sztupy's original Steam module)
6. Tegrak's kernel (onenand mode)
7. Zenkin's YA-OK kernel (based on raspdeep's oc kernel) this should be discontinued already.
There you have it.

wrong. i don't use Sztupy kernel as base. i use Sztupy steam module in the recovery.
the kernel is all modified by me.
**DamianGTO Steam kernel. 350MB Ram. 500HZ. Ext2 on all partitions. js3 base**
Hm, it would also be great to have links to all of those kernels, their details and source code... Eg.:
SpeedMod - details http://forum.xda-developers.com/showthread.php?t=822756, kernel http://forum.xda-developers.com/attachment.php?attachmentid=511980&d=1297145484, cwm http://forum.xda-developers.com/attachment.php?attachmentid=511983&d=1297145637, source http://forum.xda-developers.com/attachment.php?attachmentid=512228&d=1297167793
Voodoo - http://project-voodoo.org/
...
I've used Hardcore's, Supercurio's, and Trasig's. Right now, I'm using Voodoo 5.4.1.
In my opinion each of the three (EXT4 lagfix applied) have their own benefits.
Speedmod is the best on battery but the worst of the three for speed. It's still fast, don't get me wrong, but the real benefit lies in the speed to battery-usage. Keep in mind, Hardcore's update schedule, it's; test, stable, test, stable, etc.
Advanced Voodoo is the fastest due to the overclocking ability. Truth be told, I didn't have this kernel on long enough to really test battery life (went to Darky's 9.2 and I read that some people were having issues pairing these two). I did, however, have a bit of fun with benchmarks when on stock JS3 and the word "niiiiiice" just seemed to pop out here and there. This one isn't updated as fast as the other two.
Voodoo, I find to be a good, stable, and decently fast kernel. It's between the two in terms of speed and has been a kernel that I have used and trusted for quite some time with my SGS. Supercurio has, as of late been putting out a lot of updates though, primarily for Voodoo sound. If you have the time to flash a new update at least once a week, you're good to go.
Hope I helped you guys out.
I use Speedmod K13A with JS2, and I am really pleased of itt...it only scores 980 in quadrant, but it is very smooth and fast and has a good battery life
i use speed mode always

from what i hear, speedmod is the best kernel when it comes to battery life.
i was thinking of using lanight rom for captivate but it has devil kernel. can i flash speedmod kernel to it? which is better considering that i give most priority to battery life.
also, what are the advantages of different kernels?

LANIGHT is not a Froyo ROM (2.2), therefor it won't work with speedmod.
When choosing your kernel, make sure you they support the same firmware.
To know more about each kernels, read their OP and changelogs.
