So, over in the i9000 forum z4ziggy has been working on z4mod, it is similar to Voodoo, it completely replaces the file system with ext*.

Check out the original thread:

http://xdaforums.com/showthread.php?t=797672

Currently our kernel only supports ext2, which is sad, but here is the patched kernel, apply it with odin in the PDA slot.

Download kernel (Froyo 2.2):

http://www.multiupload.com/N1OUL0ZYYN

Download Odin:

http://www.multiupload.com/KK1GOK9SYT

Next you will need to run this zip from rom manager, the patched kernel has a borked version of 2e recovery that doesnt let you select anything, so if it fails, you will need to reboot and try again with rom manager.

Download EXT2 zip:

http://www.sgscompilebox.dreamhosters.com/files/z4mod.ext2.update.zip

If you want to revert back for whatever reason, just use this.

Revert Back to RFS:

Enjoy!

If you post quadrant scores I will hunt you down and slap you with a very large trout!!

Thank you

[Captivate Android Development] abezapata:
i am going to give this a try right now.
[Captivate Android Development] Sqdnguns:
Buwahahahahahahaha....................who reads?

Be careful though, **** splatters.........
[Captivate Android Development] Fortune090:
Should mention somewhere that this is for 2.2 DG. ;)
[Captivate Android Development] Dani897:
is the patched kernel for froyo? i can see that the patch will work on froyo or eclair but you posted a pre-patched kernel, or am i misunderstanding something?

edit, i see. nevermind i missed the froyo in parenthesis
[Captivate Android Development] alaiwy:
I tried going into CW recovery and mine when it rebooted to go into recovery it errored out and i couldn't get back into the OS. I had to redo my ROM again just FYI. Not sure why it wouldn't load back.

Do you know why my CW wouldn't load DG? Not sure how to apply the fix if I can't get into CW recovery.
[Captivate Android Development] designgears:
Yup, when I slap them with the trout their **** will splatter all over!!!
[Captivate Android Development] vunuts:
Apparently, if you've deleted Touchwiz and replaced it with LP, it won't work. Boots up pretty damn fast and the drop down menu has absolutely no lag!!! That's all I've been able to test ATM. Flashing back to stock, then back to Cog2.2B2.
[Captivate Android Development] mr.jaguar:
is this going to give us any real world performance increases? and no.. I'm not going to run around posting screenshots. besides, with the years I spent on IRC, I've been trouted enough times to know it's SHTANKY!
[Captivate Android Development] Lencias:
OMG I GOT OVER 9000 IN QUADRANT WITH THIS FIX! OMGOMGOMGOMG!

**eyeroll** =P
[Captivate Android Development] Purpleness:
I flashed the kernel with Odin then tried to apply the .zip with rom manager.

It failed. Now my phone keep on booting into the recovery screen...and i cant make it reboot regularly to try again.

Help?
[Captivate Android Development] derekle:
omg i got the same problem!!! help!
[Captivate Android Development] Purpleness:
I fixed it. I just flashed the PDA from my version of Cognition (v6). Now it rebooted into recovery, only this time it worked.
[Captivate Android Development] vunuts:
Successfully updated it, but it seems to have no Android Market app???? I installed my TiBu of Appbrain, but it says I can't download anything without having Android Market installed. Have an .apk for that DG? Or anyone for that matter? Other than that, it is pretty quick :D
[Captivate Android Development] Purpleness:
NOOB QUESTION: In rom manager do we click "install rom from sd card" or "boot into clockwork recovery"
[Captivate Android Development] vunuts:
Download recovery.

Reboot into recovery.

If it doesn't go into Clockwork (green screen) automatically, just in regular recovery, select reinstall packages. Should reboot into Clockwork.
[Captivate Android Development] Purpleness:
Thanks, i think my problem was that i had never gone into clockwork mod recovery before. With the modified kernel it is impossible to reinstall packages. I flashed to cog 2.2 kernel then reinstalled packages. Then flashed back to modified kernel. Now it should work.

EDIT: Worked :)
[Captivate Android Development] crazililazn:
lolwut? its in the OP. The last .zip file reverts the file system from ext2 back to rfs.
[Captivate Android Development] g0dzilla32:
Lol... Joking about master clear but the zip in the op didn't work
[Captivate Android Development] crazililazn:
hmm, well then i would say wait for dg, maybe he will fix it, or yeah, probably have to do the master clear.

Or, it can be good ole user error :P

just saying, but i dont get why you want to remove it. Compared to oclf, this works much better. it actually fixes some of the leftover browser lag that froyo has. Not saying it is completely gone, but this does a much better job that oclf :P
[Captivate Android Development] MrByte:
OK. Finally made it to install z4mod. In the beginning I thought there was something wrong with my pics using the Gallery app. Many where blank and/or took a while to load. Solution: killed the .thumbnails folders on both the internal ane external sd cards and let it re-create it. Now there is a huge difference!

Oh, and the Qua... never mind ;)
[Captivate Android Development] opcow:
It didn't work for me either.
[Captivate Android Development] waghoba:
Well I guess not! I have already posted before your above post, that I started from the already running Cog 2.2 Beta 6 and it went smoothly no problem at all!:D

Just for information (to anyone who want to install this mod) : undo all kinds of lagifxes and restart phone before you do any kind of new lagfix or Flash any ROM. In this case if you have OCLF, then revert the OCLF as instructed by OCLF app, restart the phone and then you can directly apply this MOD by copying it on sd and flashing clockwork recovery then reboot in download from RM and install packages from SD!

oh...and always backup everything in case something goes wrong..
[Captivate Android Development] ranjo65:
After three failed attempts, finally got z4 up and running. What did the trick for me (as others have noted here) was to reboot into CW before flashing ext2.zip. (I did it twice, actually, just to be sure...once before flashing the kernel and once after.) Anyway, all I can say is that this thing flies!
[Captivate Android Development] amerikian:
Once you flash the kernel and the update.zip, can you flash another kernel if you need to get back 2e fully functional ?
[Captivate Android Development] ice3186:
question

So dont destroy me if its already been answered but is anyone else having internet issues? Every time i flash it(i have about 4 times now) all i get is no internet on a blazing fast phone! Anyone know whats up with that?
[Captivate Android Development] gotfolk:
phones to fast for the slow internet in your area... :D
[Captivate Android Development] dowenprs:
I've searched the thread and didn't really find an answer. Is there a way to revert back to RFS without doing a master clear? The rfs.update.zip on the first page doesn't appear to be working for me, anyone have any luck getting that working? Or will i just need to master clear if i want to flash a new rom?

Thanks!

Dan
[Captivate Android Development] newter55:
Did you not get the z4 logo when you ran the rfs.zip?

Just wanting to clarify where you are getting stuck at...

I ran the zip and it appeared to work though I did get hung at the broken 2e recovery screen

Sent telepathically using vulcan mind meld app.
[Captivate Android Development] dowenprs:
I ran the zip, got the z4 logo, it ran real quick, no error message, and then it booted up. It didn't actually convert it back though, it ran through the whole process very quickly. Tried it twice already, I may just keep trying. I was really hoping to give the ASOP Cog a try at work here, haha. If i have to master clear, no big deal, just want to give the ASOP a try.

Peace

[Captivate Android Development] mcord11758:
Is there a way to do this without using Odin
[Captivate Android Development] CmcNsm:
Has anyone else installed this on beta8?
[Captivate Android Development] drancid:
I have to swap the kernel even if I flashed cog beta8??
[Captivate Android Development] m1k3-:
Nice to see some others are running this rom.

I applied z4mod via odin. Afterwards, I was unable to get back into CW recovery - I even tried to apply the recovery patch as suggested in the original instructions via ROM Manager.

Has anyone else running DG's AOSP rom been able to get back into CW after applying z4mod?
[Captivate Android Development] airbillion:
I would like to know this as well. Can we just apply the z4mod or do we have to flash the kernel with the new cog beta8?
[Captivate Android Development] drancid:
Cause beta8 uses i9000 kernel as well..

I really wanna try this without kernel swap to see what's up but unfortunately I dun have PC with me..

I dun feel safe without PC cause I can make my phone brick!! I'll try at home and post the result.

Need to flash beta 8 from 2.1 stock anyways... cause I have mms/SMS issue..
[Captivate Android Development] CmcNsm:
I flashed the mod as soon as i installed beta 8. At first it deleted the market. so i had to find a way to install the market back in thanks to an apk i found. Now everything works well.
[Captivate Android Development] PuffinNugz:
i did too, except it screwed me all up. no voice, no wifi. gonna try it again...
[Captivate Android Development] DOAlaboratories:
This may be overkill, but I safely ran v1.0 OCLF over this and it's responsive to the touch. I probably shouldn't reccommend this though, with data loss and all that.

Sent from my Cappy using mental telepathy, *****ezz.
[Captivate Android Development] drancid:
I just flashed without kernel swapping with no problem!!

COG 2.2 Beta8

Edit: oops!! my phone just reset to default cog 2.2 beta8. all apps and data gone.

Edit2: never mind... it doesn't look like lag fixed... everytime i tried to flash z4mod, CW mode said it's been completed but it just reset my cappy to default. (just fyi, quadrant score is same with or without z4mod)
[Captivate Android Development] ranjo65:
It's working for me. After I flashed AOSP B3, I booted into CW, rebooted, flashed the kernel via Odin, booted into CW a second time, rebooted and then applied z4mod. Right after that I applied the Darkness v1 theme via ROM Manager with no problems. I just booted into CW after reading your post and it still works.
[Captivate Android Development] mr.jaguar:
ok, just installed this, sometimes it helps if you re-read the instructions, as I blew it the first 3 times I tried the install. phone just rebooted from the ext2update and it seems pretty snappy.
[Captivate Android Development] InsaneJester17:
I tried this this morning, went from fresh odin'd Cog 8.1, boot, then flashed the modified kernal using odin, then tried to install z4 from rom manager but all I got was stuck at a bitmap error. :-(

Am I missing something?
[Captivate Android Development] ranjo65:
I had this problem as have others. The trick seems to be booting into CW before you install z4mod through ROM Manager. That's what worked for me at least.
[Captivate Android Development] InsaneJester17:
I'll give that a try when I'm home. Thanks!
[Captivate Android Development] fatttire:
I also had this error, but I was able to adb reboot from the bitmap error screen, and then I used brute force: repeat, fail, repeat, fail and on about the 7th time it went through
[Captivate Android Development] jslee1020:
can anyone confirm if z4mod gets wiped when I use odin one-click?

Is there a way I can confirm if z4mod is there or not by using "mount" in adb? What would I look for?
[Captivate Android Development] evertec:
I know DG doesn't want us to post quadrant scores but you can at least use it to check if the lag fix is applied. Scores should be at least 60% higher than the galaxy s that's in there by default
[Captivate Android Development] CmcNsm:
Is the phone suppose to reboot on its own after the mod is installed? cuz mine said rebooting but does nothing. i usually reboot it myself. Any thoughts?:confused:
[Captivate Android Development] daandman:
Will I lose this if I flash a new ROM or wipe my phone?
[Captivate Android Development] fatttire:
Yes, you need the kernel patch for it to work.
[Captivate Android Development] \/icious:
Its not so much posting quadrant scores in general as it is posting quadrant scores to quanitfy quality/performance.:)
[Captivate Android Development] airtower:
Has anyone else had issues flashing the kernel? Odin is hanging at zImage
[Captivate Android Development] bjabah:
I never could get mine to flash putting the kernal in pda by itself. I used the pit file from 2.2 beta8.1 and it flashed in about 3 secs.

Make SURE you have flashed recovery in RM before doing this and have the file on your sd card.

It makes me happy with froyo finally, all of DG's beta's lagged for me compared to voodoo (can't wait for Voodoo 2.2)

bja
[Captivate Android Development] jslee1020:
I never had problems with the install... BUT... doesn't seem to make it faster... I felt like cognition was snappy by itself, albeit there was some occasional stutter... with z4mod it just felt choppy
[Captivate Android Development] newter55:
It really depends on what you are doing with your phone...my wife and daughter have captivates with no lagfixand minimal lag but they really just use them as sms, occasional gaming devices

On the other hand,, I notice it on mine aster I get everything loaded back up and start using apps that need to access large amounts of data as well as with launcher pro at times

Sent telepathically using vulcan mind meld app.
[Captivate Android Development] peachpuff:
So when is DG going to incorporate this into cognition? Maybe at least have it optional.
[Captivate Android Development] drancid:
DG said voodoo is just around the corner so he is waiting for voodoo comes out and me either!!!
[Captivate Android Development] waghoba:
I once got screwed when installing z4mod on cog 2.2 beta 8.1, but I was having it on beta 7. To be honest it was nothing like voodoo. with voodoo you can actually feel the speed while downloading and installing new apps as well as running games. So I am also desperately waiting for voodoo...!
[Captivate Android Development] shoefly:
Considering z4mod is ext2 which is most definitely faster than voodoo's ext 4 and we have never had voodoo on froyo for the captivate your post makes me wonder if you have a clue as to what your saying.

If by chance your comparing z4mod that's only partially done on froyo that's an early leak atbest for the captivate to voodoo on eclair , id say your comparing apples to oranges
[Captivate Android Development] airtower:
Tried that as well, but the flash still hung at zImage. This time the screen went blank and required a battery pull to get it to power on. Came back with computer -/- phone, so it's back to JF6, then cog2.2b7. Thank god for a working download mode!

I'm just going to wait for voodoo to be baked into cog, beta7 is plenty snappy for me!
[Captivate Android Development] magistrateee:
How do we know if the mod has been successful or removed without the use of any benchmark scores?

Are there any linux/adb commands?
[Captivate Android Development] waghoba:
This is posted few pages before....

and ideally you should get following if its successful:

No idea about how to check whether it's removed or not. I guess running the same command...:confused:
[Captivate Android Development] hansmrtn:
Could someone please upload a mirror for 8.1?
[Captivate Android Development] waghoba:
May be I am comparison is wrong as you said as I don't have any idea about Linux file system :o but I was just sharing my experience that voodoo on eclair was amazingly fast...may be someone will come up with similar on froyo!
[Captivate Android Development] tehsam:
revert to rfs?

I saw a few pages back that some people were having problems reverting to RFS with the update.zip., but I can't find a definitive response to the issue.

I'm also having trouble. When I run the .zip, it opens just fine in CWM recovery, I see the z4 logo, and then it runs really fast (as if it isn't doing anything). It then says everything is complete and I reboot, but based on the Quadrant score I can tell there is still a lagfix applied.

I don't mind master clearing the phone through odin 1-click, if that will remove it. Just want to make sure I won't run into any problems trying to master clear...
[Captivate Android Development] newter55:
The rfs zip does not work so you should probably odin stock and master clear just to make sure that the z mod gets erased

Sent telepathically using vulcan mind meld app.
[Captivate Android Development] ewingr:
Subscribing.....
[Captivate Android Development] designgears:
Well, you also have to consider the performace gap between stock 2.1 and stock 2.2.

You won't see the same performace gains on 2.2 w/voodoo like you did on 2.1 because 2.2 also has JIT and it pretty quick right out of the box.

Right now I am playing with compcache and z4mod together... :)
[Captivate Android Development] thumper_1151:
I Can't wait to see this!
[Captivate Android Development] Haloruler64:
Noob question here :P

If I flash z4mod over Cog 2.2 B9 (with Voodoo disabled), and I have to flash to B10, can't I Odin over it without disabling it? Doesn't Odin reformat /data anyway? I know Voodoo doesn't have to be disabled to Odin, is this the same?
[Captivate Android Development] designgears:
ya, its the same, you can odin without any issues.
[Captivate Android Development] smokestack76:
Have you had good luck with this working with your kernel DG? Havent tried this one yet but seen where you might switch to it for COG.
[Captivate Android Development] designgears:
ya, but the recovery the put in is messed up still, they switched to clockworkmod recovery and they are still working out the kinks :)
[Captivate Android Development] Haloruler64:
Thanks!

[Captivate Android Development] wilsongis:
How does the performance differ between z4mod and voodoo on your ROM? I have tried z4mod on B8 and voodoo on B9.x but without a side by side I cannot tell. I guess I could look at Quadrant but if I remember correctly there was some type of threat about trout and a slap to the head.
[Captivate Android Development] WickedStyx:
I already flashed the patched stock 2.2 kernel that shoefly posted in the original thread. Is this kernel any different?

BTW this thing is so fast now. Quadrant score is... never mind :D
[Captivate Android Development] Dani897:
before you do anything choose flash clockwork mod recovery.

either one is fine. go into clockwork mod recover atleast once before you flash the kernel, sometimes it doesnt work the first time so you need to reinstall packages.

once you have clockwork mod confirmed working then flash the kernel and then use rom manager to either install zip from sd card or reboot into recovery.
[Captivate Android Development] Dani897:
working and it definately improves performance on bootup when the phone is being bogged down but otherwise useless like any other lag fix, ill probably remove it to prevent me from forgetting to remove it before i flash something like ive done with other lagfixes but i was just curious.
[Captivate Android Development] DOAlaboratories:
well this was a huge ***** slap to quadrant :D

sooo nice and quick/smooth
[Captivate Android Development] Demented71:
If this is still ext2, what are the main differences between this, and the OCLF?
[Captivate Android Development] shengshuyang:
why not include this in next version of Cognition?...All right, im too lazy to do any kernel swap thing...
[Captivate Android Development] shoefly:
for those that get stuck in the broken 2e recovery just use adb/android commander/droid explorer to reboot back to normal and try again with clockwork. Iposted all this in the z4 more thread that DG linked to on the first page
[Captivate Android Development] msm903:
this works fine getting me to apply the lagfix, but I was unable to remove the lagfix. i was ab le to flash over with Odin 1 click without any issues though.
[Captivate Android Development] tytdfn:
Ughh dg! You beat me to posting this thing. Oh well I knew someone was going to bc I was waiting until the mod converted more than just the /data. Its all good tho.still love you ;)

Yay no more fc
[Captivate Android Development] Dani897:
Ok that was not expected, it fixes the shadow bug in nenamark1 and the freezing issue. 52.3fps, I can barely beat that with overclock and voodoo in eclair. Imop this works better than ext4 voodoo and Despite it not blowing the quadrant score our of proportion like other ext 2 lag fixes I think this is the fastest fix yet.

Edit: they may have updated nenamark1 so I dont know if the couple fps over stock froyo is do to that or the lagfix.
[Captivate Android Development] vietphunguyen:
is the cog kernel the PDA or PHONE file?
[Captivate Android Development] bamonkey:
lesson time:D Kernel is always PDA, the modem will always go into phone and CSC is CSC *language if you really want to know*

this has been your lesson of the day come back next time for unit 2!!!:p

EDIT: unit 2 is check the OP...sometimes your answer is right on the first page
[Captivate Android Development] vietphunguyen:
Thanks heres what happened:

1.) Put phone in download mode

2.) Loaded kernel.tar with odin

3.) Loaded the z4 mod with ROM Manager (app)

4.) It failed like the OP said

5.) Took out battery and loaded "kernel-captivate-stock.tar.md5.tar" in odin, got into download down with button combo

6.) When it boot up it automatically ran z4mod with clockwork

7.) when the mod was done, I went into att screen bootloop

--- I thought i broke it here ----

8.) Took out the battery and loaded the kernel.tar and it worked
[Captivate Android Development] thumper_1151:
According to what I can find in the original tread this can be used with any kernel so i should be able to try this with ASOP beta 3, has any one tried it yet?
[Captivate Android Development] DJNgoma:
I'll try this when the next CogYo BETA is baked :P.
[Captivate Android Development] Demented71:
My sentiments exactly. Definitely want to try this out, but just got my beta 7 all set. I'm one that likes to go back to stock each time I flash so I'll be patient. At DG's rate, a new cog should be here any day now.

;)
[Captivate Android Development] warri:
Just applied this..no issues installed fine and is ruining smoothly..
[Captivate Android Development] provoked:
Not sure if this helps anyone, but here is what I had to do.

1. Flashed CDE beta 3

2. Reboot download to flash this kernel

3. Boot up normal

4. ROM Manager -> Install zip from SD Card

5. Phone reboots, sets up clockwork, then fails.

6. Reboot normal again

7. Go into ROM Manager again and install from zip

When phone rebooted into recovery the 2nd time, it automatically started applying the z4mod. Works like a charm!

Trying to avoid using ODIN of I don't have to, does the flash_image adb command work on the Captivate? I'm thinking I could flash the kernel image then do the rom manager part if it does.
