The original SpeedMod kernel, now available for AT&T Captivate users! This kernel aims to be fast, compatible, stable, and have good battery life. It makes our Galaxy S run the way it should.

This kernel is for the AT&T Captivate (SGH-i897)

The forum thread for the GT-I9000 version is here: http://forum.xda-developers.com/showthread.php?t=822756

WARNING: Before you try any lagfix, make sure that you have enough free space on your Internal SD. You should have at least more free space than data+dbdata+cache combined.

Latest K13E (12-Apr) - Voodoo Sound v7. Lowmemorykiller fixes. Improved display sharpness using AMOLED processing mode in MDNIE. Support for voice calls through headphones. Check here for more info and downloads.

Thanks to sasovics and rpicaso for the I897 boot logo!

FOR BEGINNERS:

This kernel is based on sztupy's Universal Lagfix: Lagfix and root options are accessible by booting into the Recovery Menu.

To get the best speed, it is recommended that you enable all Tweaks from the Recovery Menu. Tweaks are under SpeedMod features. Info on Tweaks: http://forum.xda-developers.com/showthread.php?t=813309

Hardcore - since you're one of the few still using universal lagfix, I have to ask if you've messed around with Steam at all? I have it booting perfectly on JPY, some issues with filesystem conversions, nothing major. Seems to work perfect on 2.2 ROMs so far.

Glad to see it come together hardcore! ... big thanks!...testing now

EDIT
Im adding my Quick FAQ to the first page so everyone can see it....

(Some of this is taken from Hardcores FAQ...READ IT!)

[Q] What do all the tweaks in CWM mean? And which tweaks should I use?
[A] The speed tweaks in CWM is taking from Hardcores Startup Speed Tweaks here, http://forum.xda-developers.com/showthread.php?t=813309. You should use the first 4 tweaks, as the optional tweaks are only support for TUN and CIFS, if you dont know what they do then you do not need them.


[Q] After I flashed this kernel my screen does not rotate correctly..
[A] You have flashed the wrong version, there are 2 versions of this kernel, one for the Captivate and one for the i9000, the correct one will say i897 in the file name, make sure its there

[Q] After flashing this kernel, I have static, crackling..etc using bluetooth or during phone calls
[A] Chances are your using a Captivate modem, this is an i9000 kernel tweaked to work on the Captivate, so you need to use an i9000 modem, theres quite a few to choose from (JK3, JK4, JL2, JL3..etc) Theres a link in my sig, under the modem I use, where you can download

[Q] Im using JPY or another i9000 rom, do I need to flash the Captivate version or the i9000 version?
[A] You need to flash the Captivate version. This kernel is an i9000 kernel but the Captivate version is reoriented so it works correctly on the Captivate, the i9000 version is for the actual i9000

[Q] Do I need to disable lagfix coming from a previous version? (ie. K12K to K12L)
[A] No, you do not need to disable lagfix when switching to a newer version

[Q] I am currently using a Lagfix. Do I need to remove the lagfix before changing kernels?
[A] If you are using a loop lagfix like RyanZA's One Click Lagfix (OCLF), you *must* un-lagfix first. But if you are upgrading from another Universal Lagfix Kernel or Voodoo, you don't need to remove the lagfix. However, it is always safest to remove the lagfix before changing kernels.

[Q] Which lagfix do you recommend?
[A] I recommend EXT4 All lagfix, with the SAFER ext4 mount option. Other lagfixes have a high risk of data loss if the phone crashes or is suddenly powered off or rebooted

[Q] Whats the difference in the "warm" and "cold" versions?
[A] If you screen is to yellow, flash the cold version, it makes it more blue to even it out. If your screen is to blue, flash the warm version, it makes it more yellow to even it out.

[Q] Whats the difference between the 250HZ version and the 500HZ version?
[A] HZ is an internal timer value used by the Android/Linux kernel. It affects the timer granularity of some kernel functions. The higher the HZ, the smoother the User Interface should be, up to a certain point - too high a HZ value will make CPU-bound tasks slower. However, the differences are very minor.

[Q] When I try to go into recovery I now have 3e and says ..

Code:
[COLOR="Red"]Install from package
Finding update package
Opening update package
Verifying update package
E: failed to verify whole-file signature
E: signature verification failed

Applying Multi-CSC
Installing Multi-CSC
Installation aborted[/COLOR]

[A] Follow my guide here, takes about 2sec and your good to go.. http://forum.xda-developers.com/showthread.php?t=909213


Thats all that I can think of right now, if theres anything else that I forgot let me know and ill post it...

Right when I thought I was set to flash a new kernel (Nandroid backup, Titanium backup, SMS backup, everything on SD ready to flash), you throw this at me... What to do what to do... >.<

Yea, I was actually just thinking that when I read the op for the 3rd time :) thanks for the possible red flag though, possibly saved me a head ache ;-)

Sent from my GT-I9000


You CAN run this with an i9000 rom, its built off of an i9000 kernel...just tweaked to work correctly on the captivate

Read the 1st post again, "Built from JPX sources"

    Updated test: K12Q-T7:

    This version is unbelievably smooth!

    Android Logger (logcat) disabled by default.
    Kernel debug messages have been disabled.
    Fixed the super loud notifications with Voodoo Sound.

    Changes from K12P:

    - Disabled Android Logger (can be re-enabled via Tweaks)
    - Disabled all kernel debug messages (printk) for efficiency
    - Changed boot logo to I897 logo for AT&T Captivate version
    - Changed /cache to ext4nj in recommended ext4 lagfix to fix large Market downloads
    - Optional IPv6 Privacy support in Tweaks
    - Voodoo Sound v2 compatible
    - Fixed loud notification problem with headphones
    - Fixed popping / clicking noise when music and FM radio is stopped / started
    - Better FM Radio sound:
    - - Really removed the high pass filter and DRC from FM Radio (restores full bass)
    - - Turn on 4FS mode for ADC in FM Radio (smoother high frequencies)
    - - Turn on 128x oversampling for ADC and DAC in FM Radio mode
    - Adjusted volume of FM Radio and Media Playback to be similar
    - General sound quality improvements:
    - - Maximized digital mixer output to improve SNR and resolution
    - - 128x oversampling option in Voodoo Sound enabled by default
    - - Explicitly disable DRC and NG during media playback, if +1.5dB mode is NOT selected

    For the AT&T Captivate version, ignore changes for FM Radio.
    8
    Reserved for future use.

    Test version K12S-T3:

    - Added 3-pole headset calling support: voice calls go via normal stereo headphones if attached, otherwise they go via the earpiece
    - Fixed mic problem, now the mic works
    - Voodoo app headphone amplifier control also controls headphone output level for headphone voice calls
    - Voodoo Sound v3

    Credit goes to xcaliburinhand for some of the source code changes.
    Unfortunately xcaliburinhand's patch didn't work out of the box - the mic didn't work. I had to modify the driver further to get the mic to work.

    *** Note: The voice call sound doesn't automatically switch between the earpiece and headphones if you plug-in or unplug the headphones while the call is in-progress. You have to toggle the speaker mode to make it switch.

    SpeedMod + Voodoo Sound test version!

    K12L-T5:

    Changes from K12K:
    - FM Radio sound quality improvement: removed Dynamic Range Compression
    - Voodoo Sound v1: FM radio bass fix, controllable headphone output via app
    - rear speaker volume +1 for media
    - light sensor polling interval changed to 2s instead of 0.5s
    (saves battery, more stable brightness levels)
    - light sensor sensitivity adjusted so that the screen doesn't turn bright so easily
    (saves battery and reduces screen burn)
    - adjustments to IO Tweak (super smooth now!)
    - changed battery level polling interval to 60 seconds, from 5 seconds

    Note that you need Supercurio's Voodoo app to adjust the headphone level. If u don't install it, the default level is the same level as K12K (+1 from Nexus S, or +3 from SGS).

    PS. The FM radio sound is really awesome after those voice filters have been removed!
