(Just checked and the same thing happened to me...tested below and it works 100%)

If it says 3e in recovery...then do this..

1)Download and extract the file below

2)Use a terminal emulator or ADB and type.. (or you can use Root Explorer or SGSTools to mount RW)

mount -o rw,remount /dev/block/stl9 /system

3)Use a file manager like Root Explorer and copy the recovery file to /system/bin and replace the one there

4)Now, reboot and you should have a modded 3e recovery with no signature verification

5)Go back to Rom Manager and install CWM

6)It should now install CWM and all be back to normal
[Captivate Android Development] Fortune090:
Guys, Quadrant scores mean noootthiinngg... I applied this kernel over Perception 8 no oc/uv w/Voodoo and immediately I noticed DRASTIC speed differences. This kernel is AMAZING. Major props, man! I love this kernel!

Something random, I was starting to get unexplained FC's on startup before. It would hang on the Perception startup screen for a few seconds, then the force close would happen and it would start normally. No idea what it was... But I flashed this kernel and it's gone now, sooo. :D

But really, thanks! Gonna be keeping this on my phone for quite some time. ;)
[Captivate Android Development] androidRIOT:
I appreciate all the help. Recovery is back and this kernal is extremely fast. I still have the i9000 boot screen but whatever. Only thing left to figure out is why I can't reboot via the side key. I either have to pull the battery or use rom manager. :/
[Captivate Android Development] Fortune090:
The I9000 Boot screen is there because this is an I9000 kernel. That boot screen is part of the kernel's boot process.
[Captivate Android Development] amtrakcn:
Works great here, cannot recall if the older versions of ULK change /system to EXT4?
[Captivate Android Development] diablo009:
Installed this over Doc's ROM v7 through CWM. So far so good. Will report back later on how the battery is faring.
[Captivate Android Development] MisterAnthonyxD:
So, do we have to backup and restore every time we change the. ULF's settings?
[Captivate Android Development] diablo009:
There is this line in change log "Removed test code from wifi driver.".

Does this mean the wifi battery draining bug is not present in this kernel?
[Captivate Android Development] hardcore:
I thought it'd be only fair to the Captivate crowd to release this.

Test version K12L-T3:

Changes from K12K:

- rear speaker volume +1 for media

- light sensor polling interval changed to 2s instead of 0.5s

- light sensor sensitivity adjusted so that the screen doesn't turn bright so easily

- changed battery level polling interval to 60 seconds, from 5 seconds

- adjustments to IO Tweak (super smooth now!)

In this version, on auto-brightness, the screen doesn't turn bright so easily.

I haven't tested it enough to see if I've gone too far with the values, although it should still hit max screen brightness at the same brightness in the original settings.

I'd be interested to know if you think it should go brighter sooner or even later.
[Captivate Android Development] existz:
As always, much appreciated!..been watching this closely in the i9000 thread, any difference in battery life?
[Captivate Android Development] joeshmoe08:
Want to know how it compares in battery life with version i. Also what does - changed battery level polling interval to 60 seconds, from 5 seconds" mean?
[Captivate Android Development] Barbarian:
Sweet. Going to give K12L-T3 a run.
[Captivate Android Development] jaxf250:
Downloading and will test out tonight and tomorrow - thanks HC.;)
[Captivate Android Development] Majortom420:
Alrighty thanks, I figured out the etc/wifi copy paste part but what is the META-INF?
[Captivate Android Development] smitty5569:
How do you install this? I've never installed a kernal before.

Could someone post me to a tut or tell me how?

Big thanks. :)
[Captivate Android Development] bamonkey:
Thanks Hardcore, testing the new kernel now!

was MIA due to being an overnight worker so ive slept since then:p

modem is currently something of a debate really. Ive personally loved using JK4 and JL3*current using*...to be honest i keep both modems handy to flash because i sometimes i see a difference and then other times not:confused:

results could vary so i can only give an opinion

EDIT: to your above on the meta folder...its just for the update script on CWM so for your method they are not needed...just the files in the update folder

there are references AND im going to assume youve flashed a rom before *not completly new* and have clockwork recovery. basically download the file from here that ends in CWM and reboot to recovery.. choose the file on your INTERNAL sd card and boom..done.. there are other ways (i probably flash a new kernel every 3 days) but this is the easiest way to flash hardcores kernel....enjoy
[Captivate Android Development] mengbo:
I would suggest to change the i9000 boot screen to something else. I believe there must be some better screen than it.
[Captivate Android Development] :
Im d/l this straight from my phone and then selecting open (so it auto reboots/installs with this file) and its bombed out twice saying 'signature verification failed'.
[Captivate Android Development] bamonkey:
well hardcore does use the i9000 galaxy S phone so i imagine hes not to concerned with it LOL:D

I have pondered making my own boot image for this kernel...but ive still got tons of xmas games that keep me preoccupied right now:p
[Captivate Android Development] mengbo:
Put the cwm zip file into your sd. Use Rom Manager to recovery mode. Flash that cwm zip file from the menu. Reboot. Done.
[Captivate Android Development] existz:
If it says 3e recovery then use the guide I posted in the first 10pages in this thread (dont know exact page) or the guide in my 3e recovery modded thread

The zip is setup to flash via cwm, thats what meta-inf is for, just extract the zip, in the /zip/system/etc/wifi directory copy those files to your system/etc/wifi directory or flash via cwm, its the easiest and takes 2sec
[Captivate Android Development] jhernand1102:
I assume that I can flash right over the top of K12K ?
[Captivate Android Development] existz:
Yes, you can just flash over using cwm, odin or kernel flasher
[Captivate Android Development] jhernand1102:
Thanks.......:-)
[Captivate Android Development] arcardinal:
Hardcore, been running k12l-t3 since you posted it up. Everything is running fine. One thing I've found is necessary is clearing the dalvic cache after each new kernel flash for no problems. If I skip this step I seem to experience freezing and force closing until dalvic is cleared. Thanks for your great work.
[Captivate Android Development] RonH54:
What exactly is held in dalvic cache?

Thanks
[Captivate Android Development] sjavvaji:
i love you for the rear speaker increase...i find that this version consumes less battery for me for some reason...i lose 1-2% an hour

[Captivate Android Development] WickedNite:
So what Modem is the partner of this Kernel to conserve battery? I mean JK4? JL2 or something else? Or it really depends on the phone itself?
[Captivate Android Development] jhernand1102:
I'm using the JK4 and battery is great. I can get an easy 18 to 22 hours.
[Captivate Android Development] WickedNite:
How many percentage does it lose hourly? And what rom do you use?
[Captivate Android Development] jhernand1102:
I'm using Phoenix 3.0 and I lose about 2% an hour in standby. YMMV:)

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!
[Captivate Android Development] *** Adrian ***:
I really loved this kernel!!!

Perception 10.1 + K12L-T4 + TLJL3 is AWSOME!!!

;)

Will this T4 be the latest one, or more versions will come in a short time??? I dont wanna flash every morning I wake up...:p:p:p
[Captivate Android Development] Dzmitry:
FM radio works on captivate O_o ?
[Captivate Android Development] paokaras45:
can i flash K12L-T4 over K12K???

I now have K12K, entering recovery mode and installing the CMW.zip will do the job?

Are there any risks or steps afterwards? (re-lagfix, re-tweaks etc)
[Captivate Android Development] *** Adrian ***:
Yes, you can!!! I just did that, and you dont need to run ext4 again...it will be keeped...Is working awsome...
[Captivate Android Development] neptronix:
Thanks

Hardcore: Your kernels are amazing! You are really going in the right direction. Best battery ever with your kernels, as well as performance. Testing "L" out now.
[Captivate Android Development] ngochuy:
Captivate has FM radio ? I don't think so. How do u enable FM radio in captivate ?
[Captivate Android Development] Cezar`:
I'm on a Captivate, I dont know if you and supercurio did anything with the sound for the regular media but, man, the sound is soooooo much clearer!!!!!!!!!!!!!!!!!!!!!!! I am using the damn stock Samsung headphones and I am not sorry my dog ate the Creatives I had :D The sound is pure crystal! I cant wait for this to go stable.
[Captivate Android Development] Cezar`:
No it doesnt. The change log is valid for the i9000 version as well. So disregard the FM Radio fixes. However, the sound quality for normal media was greatly improved (or at least thats what my ears are telling me :) )
[Captivate Android Development] Majortom420:
I'm having trouble finding this specific modem could you shoot me a link? Thanks.
[Captivate Android Development] RonH54:
"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)"

Is this the "Voodoo App" by Project Voodoo at the Market? Also I am presently using your "K" version with Darky 8.0 and I disabled the Voodoo LagFix on Darky's before I installed your Kernel.Though I read you don't need to do this with your Kernel I still see some people recommend it, what are some thoughts on this?Though this Kernel is Fast without Lagfix if I do want to try it do I enable the Lagfix included with this Kernel though Recovery or should I just re enable Lagfix in Darky? Or is it the same thing either way?

Thanks
[Captivate Android Development] eep2378:
Just flashed L kernel will report on battery, etc.
[Captivate Android Development] phlunkie:
nevermind. see the change.
[Captivate Android Development] hardcore:
Oh I forgot about that. Well ignore those particular changes then.
[Captivate Android Development] Lancez:
oh, man! just flashed T4, and now the T5?! :D
[Captivate Android Development] Lancez:
i'm not sure if i'm 100% accurate, but i flashed L on top of K without any problems. lagfix was enabled on K.
[Captivate Android Development] hardcore:
Yes the voodoo app.

There is only one place to apply lagfix and it's the recovery menu.
[Captivate Android Development] Mevos:
@hardcore: do we really need the voodoo app for the new sound or is it just to make some personnal adjustments?

I'm gonna test this new version, thanks!

edit: precision.

[Captivate Android Development] sublimaze:
i just flashed t4. does t5 have any tweaks besides the fm radio?

sent from the midget in mah belly
[Captivate Android Development] hardcore:
Nope. If u have t4 there's no need to update, although there's no harm to either.
[Captivate Android Development] RonH54:
I want to get this correct. Since I have this Kernel on Darky ROM I shouldn't re enable the Voodoo Lag fix that is included in Darky's? If I want a "Lag Fix" I should always use the one with this Kernel? So the Lagfix here is different from Voodoo? I hate to ask dumb question but I'm not clear on the differences.

Thanks
[Captivate Android Development] hardcore:
The lagfix is basically the same but u should always enable it from the kernel recovery menu.
[Captivate Android Development] Killemalll:
I have Darky's rom as well. I flashed the kernel directly without disabling lagfix in the voodoo folder. After the flash, if you go in clockwork lagfix options menu you'll see it shows ext4 already enabled.

Also all the files from the voodoo folder created by Darky's rom are removed, only the logs are left. So basically CW Lagfix takes over.
[Captivate Android Development] RonH54:
Thanks that was the info I was looking for. Did you ever test the "responsiveness" of Darky's with this Kernel and Lagfix disable vs enabled? If so can you tell a difference?
[Captivate Android Development] Killemalll:
With no apps installed, no difference. With 250+ apps the phone is much snappier when voodoo is enabled. I also activated all the recommended tweaks in CW Speedmod menu.
[Captivate Android Development] RonH54:
I love the Combo of this Kernel with Darky ROM.
[Captivate Android Development] RonH54:
Thanks.. I been busy this morning with questions because I have hit my 5 "Thanks" limit. So I am pretty set that I will be using this Kernel and Darky ROM. Would you advise then with each Darky update I not Flash his ROM with Lagfix enabled then after I flash your Kernel then enable LagFix to be on safe side?
[Captivate Android Development] supercurio:
Yeah for Captivate, fact that you don't tick "FM" features in menuconfig will make disappear the associated controlling options in the Android app :)
[Captivate Android Development] pclaunch:
When I open the voodooo app with t5 installed it says that I dont have a compatiple kenel. Any thoughts?
[Captivate Android Development] Majortom420:
First thing I notice is that K12L-T5 is much snappier than the previous version, and the sound is clearer, thanks hardcore.
[Captivate Android Development] :
You dont have to disable the lagfix if you're going from K to L, right? Also, if Im reading this right, even if you arent using voodoo, L is louder/clearer than K?
[Captivate Android Development] existz:
Correct, you do not have to disable lagfix
[Captivate Android Development] warri:
Awesome kernel hardcore...best battery life I have ever had...running t5 (t4 before) no issues on phoenix rom.

[Captivate Android Development] RonH54:
I just enabled Lag fix though this Kernel Version K. Should Voodoo App work on K only on the newer L,it says I don't have a Kernel with extended sound controls? Also I am not sure if Quadrant Std. scores will mean anything but the Score is the same as before I enabled Lax Fix?

You want the i897 version in this thread not the i9000 version.

Thanks anyway :)
[Captivate Android Development] RonH54:
Thanks for the reply.
[Captivate Android Development] Majortom420:
Wrong kernal.
[Captivate Android Development] RonH54:
I think everything went smooth with enabling LagFix here is what I see on Lagfix Menu:

Data_FS=ext4

Cache_FS=ext4

DBDATA_FS=ext4

DATA_LOOP=false

CACHE_LOOP=false

DBDATA-LOOP=false

BIND_DATA_TO_DBDATA=false
[Captivate Android Development] Mevos:
You might not have used the correct kernel.

That was one of the issues I had when using a speedmod I9000 kernel by mistake.

i.e. the screen would rotate in landscape once but would never go back to portrait. hence why 90° off.
[Captivate Android Development] Jay120171:
The L version is just a little too dim for my tastes. I understand it is a "feature" to prevent the phone from going full brightness as much but sitting here in my office under the lights the screen is probably 1/3 the way up.
[Captivate Android Development] rafsi:
thanks for your response, following some of the advice on wi-fi setting from your response link... will run the update-wifi-dxjpa.zip later in the day and test tonight...

[Captivate Android Development] sjavvaji:
omg...what was done to the sound quality...it has improved substantially...im using klipsch image s4's and i hear a distinct change...i flashed the other kernel back to see if it was a placebo effect too...it wasn't...i love the volume improvements and the auto brightness change and the battery life...THIS KERNEL IS THE BEST EVAR

Is there anything else I need to do this kernel flash? As well can I do it all on the phone or I must use odin on the computer?

Thanks for the help/clarification on my noobness :)
[Captivate Android Development] delugeofspam:
If you're already rooted on Rogers Froyo, disable lagfix and go download "SGS Kernel Flasher" by Neldar from the market and use the -CWM.zip files in SGSKF to flash the kernel, then recovery-reboot to enable EXT4 lagfix through speedmod recovery.

Thanks I already have that setup so it should be quick.

So remove lagfix

Download file on my phone n use SGSKF

To go to recoveryreboot mode that is when I hold vol up/down and power? or just simply turn off n on the phone?

Also on start up after a pull battery I get the I896 screen, then the gaxasy s i9000 screen then rogers then the S screen after a bit of waiting it goes black.

HELP! =(

Edit, I went back to recovery mode. Dont know what to do.
[Captivate Android Development] delugeofspam:
LimaI896:

After flashing with Neldar you should be able to get to green speedmod recovery where you can use the last menu option (speedmod ULKF or something) to change your filesystem configuration, which is probably the problem. If all else fails Odin yourself back to stock and try reflashing with Neldar. You're sure you disabled one-click lag fix?

p.s. Those four bootscreens are "normal"

you don't need any extra stuff to flash this kernel, all you need is transfer it on SD card, turn of your phone, use 3 botton method get into recovery mode, then install zip from SDcard. thats all. you dont need CWM or kernel flasher.
