[Captivate Android Development] dhostetter:
Ok, another noob question. Which version of this kernel should I use?

I believe Perception 10.1 is i9000 based. I should use that version correct?
[Captivate Android Development] sixstringsg:
Use the one designed for your phone. So the captivate one.
[Captivate Android Development] existz:
Look on the first page, at the bottom, ive made a FAQ for all the basics, read over it

But you need to flash the Captivate version, the Captivate version is an i9000 kernel made to work on the Captivate, the i9000 version is for the actual i9000
[Captivate Android Development] RonH54:
I see where Darky has his 8.1 version of his ROM out and it uses SpeedMod "M" as the Kernel......:D
[Captivate Android Development] dhostetter:
I was double checking to make sure I didnt do something wrong.

Used odin to install the Cap version and when the phone boots it vibrates several times and reboots continually.

Suggestions?

I used Win7 to unzip the download to get the tar file for odin. Maybe that was incorrect?

I'll try winrar.
[Captivate Android Development] existz:
Try clearing your dalvik cache in CWM
[Captivate Android Development] xandercapy:
If I'm using SGS kernel flasher on serendipity, which version do I download? Cwm or 500?
[Captivate Android Development] existz:
Its easier to use the CWM version in Kernel Flasher, if you get the normal zip, you have to extract it first to get the .tar out of it
[Captivate Android Development] dhostetter:
cleared.

Samething.

Any other suggestions?
[Captivate Android Development] Scarchunk:
I haven't been able to flash .tar files with sgs kernel flasher here lately. Fails to flash. I've had to zip up the zimage to get it to work. Have you tried a .tar with the newest version of sgs flasher? Is it just me?
[Captivate Android Development] RonH54:
I know this is posted somewhere so I apologize now but is SpeedMod a Voodoo 5 based Kernel?

Thanks
[Captivate Android Development] Clienterror:
Negative ghost rider. It's modified off stumpys ultimate lagfix I'm pretty sure.

[Captivate Android Development] RonH54:
That is sort of what I thought. I saw on a Post on another forum discussing the need to disable a lagfix before flashing.He mention if the Kernel or Rom you were going to flash was a Voodoo5 based you didn't need to disable before new flash if the new one was also Voodoo 5 and he gave SpeedMod as an example of a Voodoo5.
[Captivate Android Development] existz:
Hardcores kernel is not Voodoo based, its similar, but its not Voodoo...As to disabling lagfix, read the whole first page, ive posted a FAQ there, also read Hardcores FAQ both cover this question...but no, you do not need to disable lagfix first, both kernels support the same file system (ext4)
[Captivate Android Development] RonH54:
GREAT info.

Thanks

UPDATE

So after running K12M for about the last 6-7hrs, unplugged around 5pm, its now 11:40pm..battery life seems to be doing really good..probley better than it has been. I would say this is with moderate use, im not going to say heavy, or lite, as I did use my phone just like I would any other day...w/ around 75 sms, 4 calls at about 1-1.5hrs total talk time, a few hours on xda app and browser, listened to music for about 45min, check email..sent 3, plus alot of other random stuff im forgetting that i done today.. This is with 3G/Sync=ON, Wifi, GPS, BT=OFF.. The lower min brightness has helped with idel, it basically does not budge when screen is off.. I say if I was just to not plug it in tonite I could probley make 36-40hrs before having to charge..if not longer..
[Captivate Android Development] switters1:
Do you have auto brightness set?
[Captivate Android Development] rlamontjr:
i cannot get the k12m-cold version downloaded from hardcore's official site. http://goo.gl/IdnWf
[Captivate Android Development] hardcore:
It's possible but I need part of the source code from the Captivate kernel - even the eclair one might work.
[Captivate Android Development] existz:
When im home inside, I turn brightness all the way down, the rest of the time I set it manually
[Captivate Android Development] Kakkoister:
I dropped from 14XX points in Quadrant Standard using Stock + Voodoo 5.X stable

http://xdaforums.com/showthread.php?t=870760

To 12XX points using this latest Speedmod. (And I have enabled all the good tweaks in recovery mode.)

Is this a known issue and is there an explanation for it? What score do other people with this mod on their captivate get in Quadrant?

Edit: Nevermind, rebooted again, let my phone sit on for a bit and then ran it and got 1412.. Still not quite as good as I was getting with just the voodo kernel, but I'm sure the other patch's this kernal has is more than worth the small bench difference.

Great work.
[Captivate Android Development] ryude:
You should stop using quadrant, it's well known as the worst benchmark. You should let real world use be your benchmark, it's never let me down. :)
[Captivate Android Development] Clienterror:
Man quadrant is a horrible way to bench this phone, and who cares if it even scores a 13 in quadrant if you think it feels fast? Back when the first lagfix was released (ex2 file system) people were hitting like 2400-2800 in quadrant but the phone was actually more laggy in real world usage than lag fixes today that get 1500.

Just my .02 on quadrant ;-)

Sent from my SAMSUNG-SGH-I897
[Captivate Android Development] Majortom420:
Amen, quadrant is theoretical, real world applications is something else altogether

Serendipity 3.0, Speedmod K12M
[Captivate Android Development] Yuna:
yeap... btw seen a video from sense rom running on cappy - quadrant cpu scores are as high as qualcomm cpu's.... looks like it's just optimized dvm from htc...
[Captivate Android Development] hardcore:
It's easy to make quadrant score 1700 with speedmod. But for the sake of your data, I didn't make it the default setting.
[Captivate Android Development] eep2378:
I'm getting wonderful battery life with k12m. I'm using phoenix 3.5 rom and I've been unplugged for 17 hours and I'm still at 70%. I'm also getting no drain when idle. Phone was idle from 9 pm last night til 7 am and it did not drain even 1 %. Thank you hardcore!
[Captivate Android Development] beerbaronstatic:
are you using auto brightness?
[Captivate Android Development] johnnysnallen:
Please help me apply to my Captivate

Thank you Hardcore and Existz. I would like to use this on my Captivate. I tried Thursday night and messed up my phone pretty bad (I'm a noobie).

So I have some questions please:

1. I have the Cognition ROM but my firmware is still 2.1-update 1,

Baseband: I897UCJH7

kernel: 2.6.29 chshrcat@alice #315

?So do I need 2.2 before I try to use this Speedmod kernel?

2. I believe Cognition has a Voodoo lagfix? so would it need to be disabled before applying SpeedMod?

Thanks!!!
[Captivate Android Development] Clienterror:
Yes this is a 2.2 kernel so you will need a 2.2 or 2.2.1 rom. And yes on the second question, this doesn't use voodoo so you will indeed need to disable voodoo first. A lot of people flash to stock then a rom then a kernel.
[Captivate Android Development] KaLiBLeeK:
I'm not sure if this is sufficient, but it's the first thing I found doing a search:

http://briefmobile.com/samsung-open-sources-captivates-code

I'd like to have the i9000 screen ditched on boot as well. One of the few things left that is tugging at my OCD. Haha.
[Captivate Android Development] ooo.stephen:
maybe you're already doing this, but i find if i don't like my quad scores, just run it again and again. i consistently fluctuate from 1330-1598.
[Captivate Android Development] Smallsmx3:
I've searched.....what does the cifs and tun support actually do? I have them enabled but I.don't know.if I actually need it
[Captivate Android Development] hardcore:
With ext4 data lagfix, you should get about 13xx-14xx with the default SAFER mount option.

You can get around 17xx with the (not recommended) faster mount option.

NEED HELP

Hey guys I need some help and it would be greatly appreciated and its probably a noob question.

1. I am running Darkys v8 with the Voodoo Lag Fix DISABLED

2. I want to get Speedmod because not only will the new 8.1 update have that I need better battery life and performance and everything points to Speedmod.

3. I have the SGS Kernel Flasher, I have a nandroid back up, and Titanium Backup of everything so if for some reason anything wrong were to happen I can always restore my nandroid back up.

Now what do I do? What is the easiest way to install this?

Thru CWM and just flash it thru there or with SGS Kernel Flasher?

Please help!

Thanks in advance
[Captivate Android Development] mcord11758:
Sgs kernel flasher

Open

Choose kernel

Click on the dots......

Navigate to where you have hardcore saved

Select

Flash kernel

Done
[Captivate Android Development] Dlev7:
Wow really that easy?

Thats amazing.

And If I dont like it I can always restore the backup Kernel I made with SGS?

Also how is your battery liofe with this and do you by chance have Darkys also?
[Captivate Android Development] Dlev7:
And we want the one that ends in CWM right?
[Captivate Android Development] existz:
Yea its that easy, but no, backups do not backup/restore the kernel, so you will have to flash a kernel back either with Kernel Flasher, CWM or Odin... For me battery is great, check back a page or so I posted a pic of the test I done with K12M

Yea use the CWM one, its easier to do with Kernel Flasher, the regular zip you will have to unzip it to get the tar out
[Captivate Android Development] mcord11758:
Should work with either but best to grab that one
[Captivate Android Development] Dlev7:
Alright and what do you mean never to restore the backup of the original kernel that came with Darkys?

Should I delete my back up or should I just never restore it, and if I want to go back to that kernel that came with Darkys for some reason (I dont know why considering he has no switched to Speedmod also) but hypothetically I would just reflash with CWM or SGS Kernel flasher right?
[Captivate Android Development] mcord11758:
There us a backup feature is sgs kernel flasher. Back up kernel there if you do not like hardcore, open app select saved backup flash
[Captivate Android Development] Dlev7:
Ya thats what I thought how come existz said, "ut no, backups do not backup/restore the kernel, so you will have to flash a kernel back either with Kernel Flasher, CWM or Odin..."

And hows your battery life and performace with Speedmod and what Custom ROM are you using?
[Captivate Android Development] mcord11758:
Your clockwork backup would not change the kernel back. That is what he was referring to
[Captivate Android Development] existz:
That was my mistake, wasnt thinking about backing up in kernel flasher, was thinking of a backup in CWM, ...my bad :P
[Captivate Android Development] Dlev7:
Oh hahah ya I made a back up in SGS Kernel Flasher.

But back onto Nandroid Backups the kernel stays the same when restoring those isnt that correct?
[Captivate Android Development] Dlev7:
Hold on whats going on Im trying to flash the CWM kernel it keeps saying Flashing Failed

What do I do?

EDIT: NEVERMIND
[Captivate Android Development] existz:
Yea, whenever you do a nandroid backup, the kernel is not changed
[Captivate Android Development] mcord11758:
Nandroids are good if you are going to mess with themes and stuff. They are useless for modem, kernel, base
[Captivate Android Development] diablo009:
@harcore:

Did something change here? I am finding the 250 Hz version instead of the standard 256.
[Captivate Android Development] DrDrrae:
K12N Cold Captivate CWM points to the I9000 version.
[Captivate Android Development] rlamontjr:
was just bout t say this. yeah there is not a "i897 K12N cold"
[Captivate Android Development] Kyuta Syuko:
I'm also wondering this though I'm guessing not...
[Captivate Android Development] Exostenza:
Running the latest N version of the kernel and it seems that my brightness is either 0 or 15 and nothing in between. This means that I cannot use auto brightness as it is either much too dark or much too bright.

Any fix around the corner so it has different levels of brightness? I know it says brightness fix, but it is not fixed :(
[Captivate Android Development] Dxtra:
I find it to be too dark on auto brightness even under my room bright light , needs to get brighter under sunlight and light. Honestly I prefer stock default auto brightness. The high brightness what makes these super amoled screen stand out.
[Captivate Android Development] existz:
Im loving the new lower brightness ..works great for me, I would almost say make it darker

Posted from my i897 running JPY, Hardcores K12N and KP1
[Captivate Android Development] Dxtra:
I'm fine with the minimum brightness. I just want to boost the auto brightness under light and sunlight. It does not get bright enough. If you can make a separate default auto brightness kernel, I would gladly appreciated if not make it brighter under light.
[Captivate Android Development] Aus_Azn:
Gah, stupid Google Documents and its access limit...
[Captivate Android Development] WickedNite:
How's the battery on the new kernel released?
[Captivate Android Development] hardcore:
Actually version N gets brighter quicker under sunlight - it reaches maximum brightness more easily than stock, but maybe the maximum brightness isn't bright enough.

I'm still working on tweaking it for the 2 extremes: darkness (more insensitive to light) and outdoors (more sensitive).
[Captivate Android Development] Dxtra:
Oh so maybe it just me, what about regular light does it reach an adequate brightness like stock or is it different on k12n?
[Captivate Android Development] upNsmokeAllDay:
Keep up the good work. My kernel of choice anymore.
[Captivate Android Development] krips2003:
@ hardcore.

Is the battery not showing 100% charge, is an issue with the kernel. This was happening on i9000 ROM 2.2.1, which I guess was a known issue with i9000 based rom. Now this is again happening on Cognition v3.02.

Thanks.
[Captivate Android Development] delugeofspam:
I've been using this kernel since the first Captivate release, and it's great!

I just don't really like the added time between light-sensor checks. Does checking the light sensor use a significant amount of battery? It would seem that changing the brightness less often diminishes the user experience (good luck taking your phone out of your pocket in the sun... you'll have to wait 2sec before you can see anything) and could actually contribute to battery drain (screen is left brighter longer by not checking to see if it's dark again).

I mean I know it's only 2 seconds here and there, but while I GREATLY appreciate the lower-minimum/higher maximum brightness and adjusted ratios, the increased time between sensor checks just seems to take away from what you're trying to do.

Again, though, love the rest of the kernel. Great work hardcore!
[Captivate Android Development] Aus_Azn:
While I understand that one is supposed to be using CWM with this, it's a bit annoying when CWM fails to load for some reason and you get stuck in 3e recovery, where the Power button doesn't select the item. Can you look into using a 2e base recovery so that we at least have another layer of fallback before Download Mode?
[Captivate Android Development] existz:
I posted a work-around on the first page in my FAQ
[Captivate Android Development] Aus_Azn:
Ah, missed that because it wasn't in Hardcore's FAQ and didn't include the terms "2e recovery" in it, "my bad".

EDIT: Smooth as silk, thanks!

I understand ..its easy to miss, was just letting you know there was a fix for it..

[Captivate Android Development] existz:
Yea I know, hardcores kernel with KP1 seems to be a match made in heaven, im working on a KP2 rom right now, im hoping since the modem was so good the rom might be good also, might have less battery drain issues than JPY..

+1 This is my kernel/modem combo. K12M KERNEL w/ KP1 MODEM!!!
[Captivate Android Development] Jdelgado:
Hi Guys,

Do you have to worry about disabling Vodoo (lagfix) before installing znkp1 on the SpeedMod K12N ?

Thanks
[Captivate Android Development] existz:
If you are already using K12N, Hardcores kernel is not Voodoo, it uses a similar lagfix, it uses the ext4 file system, which so does voodoo, but there is differences between the 2.., but no, you do not have to disable lagfix before flashing a modem..
[Captivate Android Development] Exostenza:
Just use neldar's SGS kernel flasher app with the CWM file. Easy as pie, assuming you can bake a pie with ease :)
[Captivate Android Development] Jdelgado:
thanks for the quick ans
[Captivate Android Development] NYCJOE:
Hello, just flash speedmod with cog 3.02, its great so far as it fixes the firebird 2.0 issue of no headphone buttons while still allowing the use of I9000 modems.

My only problem now is that I can't get into recovery mode to flash anything else.

I tried flashing speedmod with SGS kernel flasher and had the same problem. Luckily I flashed the JL3 modem before kernel flash 2nd time around.

After "Verifying update package" on the recovery screen I get..

E:failed to verify whole-file signature

E:signature verification failed

Intallation aborted..

I'm still able to reboot and the phone is functioning perfectly. But I would like to fix this issue so I can flash updates as they come out. Thanks

Edit- I added "disable lagfix" to the voodoo folder prior to flashing. Should I now delete the disable folder?
[Captivate Android Development] existz:
Read the first page, I posted a FAQ with how to fix this... and you can delete the voodoo folder if you want

If this can be user configurable it just might shot everyone.

Can anybody comment on the feasibility of this?
[Captivate Android Development] existz:
Check out the thread in the i9000 forum, its the same kernel but not reoriented for captivate ..there's way more input by users over there, but make sure to watch cause hardcore post his beta kernels there and I believe he's on his test versions of k12o, so some post will be about that and not k12n....but I personally am very happy with k12n

Kernel doesn't support it.
[Captivate Android Development] NYCJOE:

[Captivate Android Development] Lancez:
you can try Paragon RC1 ROM's kernel, download here. replace it with the original one in the .zip then flash it the normal way. that kernel is based on hardcore's and supports OC/UV as long as you install voltage app to adjust settings.
[Captivate Android Development] aridoasis:
newbie here...

i think it will but i just wanna be absolutelty sure... is this kernel compatible with the Rogers i896 Captivate?

*sorry, just had too much bad experience with Bell's i9000m...
[Captivate Android Development] rootnik:
YES, but make sure you install an i9000 modem too. JK4, jl2, jl3 all good options.
[Captivate Android Development] WickedNite:
JL2 is the best option for me, but as always, it depends on the phone and location.
[Captivate Android Development] sjavvaji:
can u release a test? plz...
[Captivate Android Development] aridoasis:
ok. so once i flash the i9000 JL2 modem, do i use the i897 kernel or the i9000 version of the kernel?
[Captivate Android Development] existz:
Read over the FAQ on the first page... you need the Captivate version, make sure it says i897 in the file name

Captivate version is an i9000 kernel made to work on the Captivate

i9000 version is for the actual i9000 version
