[Q] Captivate lag fix help

i'm loving my new Captivate, and i'm glad i made the switch to android. but one thing i wasn't expecting is the lag issues. i see that xda has more than a few solutions for me. but like i said this is my first android phone and the transition has been a little rocky. can anyone walk me through the one of the 1 click lag fixes? i'm on a mac so i'm already starting at a disadvantage. is there anyway i can do this whole thing via terminal emulator right on my phone?
Thanks

First, If you have access to a windows computer, try flashing this rom. its fixed alot of issues for me. including the lag.

If not follow the thread below.
but for the busybox step sideload this one cuz you need busybox 1.17.1(I've uploaded it here for you-http://www.mediafire.com/?z89f7zt9kyxb7n3)[the one in the market causes issues because its missing some commands)
follow the rest of the steps in this thread. this has worked the best for a few people I know. -http://forum.xda-developers.com/showthread.php?t=747397

Nice!!

Hi guys i have a samsung captivate . I installed froyo on it. Build number FROYO.UCJI6
I notice that when i am in applications and i browsing through i get some lag and it sometimes sticks for a slight second.. How can i fix this? i am a noob at these stuff..

I used the juiced ROM and it's great. Battery life rules and the lagfix is great.

try moving all the apps back to the internal memory, those apps that u moved to sdcard must go back to phone memory before applying the oclf

Hi guys I am new in here, dont' know if here is the right place for this question... well here it goes...
I had updated my captivate with the official UCKF1 2.3.3 gingerbread... i want to install voodoo lagfix, but I dont know if it is possible for me to install it in my rom... I am rooted..
TIA

cant use voodoo lagfix on KF1 for now period. its all kernel related and once/if samsung/att releases the kernel source then and only then can ext4 be implemented

to be honest, if your a new captivate user you shouldn't be flashing gb roms, flash to stock using odin and flash 2.2 and 2.1 roms since they are the most stable ones yet...in my personal opinion if ur a noob and want to get rid of most of the lag in your phone flash serendipity 6.4...super easy flash through cwm and it's stunningly fast,crisp and stable as hell...

Dragon ROMs, direct to ext4 install, voodoo5

What is this? It's an experimental ROM install setup that avoids the use of RFS entirely. The install basically pre-voodoo's your phone. If you know you want voodoo, this is faster than installing then doing voodoo, but it's a little more complicated. Not much, but be warned. It avoids the use of RFS durring install completely, so no RFS corruption to worry about.
The ROM itself is mostly untouched. The kernel is my Dragon Kernel, i9k based, so it will eat your battery (froyo only, eclair is better as we have source). I can get about 12 hours out of it. Buy a charger.
The new version is a 1-click install. It installs the kernel, reboots into it, then auto-installs the ROM. I tested it coming from JFD without issues.
These are based on voodoo5 beta code. Curio is releasing voodoo5 stable here soon, and I'll post an updated no-wipe kernel flash for that.
The ROMS are Team Whiskey Obsidian, Onyx, and Fusion. I changed the install procedure and the kernel out, the rest is as they made it. I take no credit for the ROM. Please post bugs here however, so I can make sure they are ROM bugs before letting TW know about them. I'm running the Onyx version as my daily driver. There has been some private beta testing, and they seem stable, but do have Odin handy just in case. I have installed over the top of various ROMs, but the safest way is probably to come from JFD just to be sure.
ALL THESE ROMS WIPE. NO, I WON'T CHANGE THAT.
Obsidian V5b: http://www.tabbal.net/files/Dragon-Obsidian-Installer-v1.0.zip
Onyx 4.2: http://www.tabbal.net/files/Dragon-Onyx-Installer-v1.0.zip
Fusion Final: http://www.tabbal.net/files/Dragon-Fusion-Installer-v1.0.zip
NOTE: THESE INSTALL VOODOO. ALL THE USUAL VOODOO PRECAUTIONS APPLY, IF FLASHING SOMETHING, DISABLE IT FIRST.
The latest voodoo stuff seems to play nicer and I have flashed things from clockwork without bricking, but just be warned.
Updates:
Kernel with the stable voodoo5 release. Should work with any froyo ROM, does not wipe.
http://www.tabbal.net/files/Dragon-Kernel-Voodoo-v2.0.zip

I can conform that these are indeed working. And they work beautifully. I'm evening thinking about going back to some voodoo love.
Love your work ttabbal.
"if you amplify everything, nothing is heard"

Hmmm...cool. Might have to try this with Axura 2.1.

Curious! So what's the true (RFS free) Quadrant score for Vibrant?

Can we have just a kernel flash that will convert all the partitions? supercurio's i9000 flash doesn't wipe the data, it simply tars it and then untars it back once the conversion is done to each partition. Thanks for the hard work.

The post is about the ROMs, but yes, the kernel update I'm about to post will convert an existing system to ext4 on reboot with the just released voodoo5 stable code.
It's the custom kernel I reference in the OP. If you want more than about 12 hours off charger, don't install it. I'm going to look at Eugene's recently posted source to see if I can implement whatever he did to get the kernel sleeping better, but no promises. And reports are kind of mixed last time I looked at it anyway.
When Samsung gets around to releasing source, we can do better. Till then, give me a patch or don't complain about it.

Nice. I'll hold off trying this with Axura 2.1 until this posted, then. A battery life of 12 hours is fine in exchange for what Voodoo will provide in return.

Sweet, thank you.

i flashed this on obsidian v5 beta w/ jk6 modem and it running like a champ. however, you were right about the battery life
thanks for posting it before hand. i appreciated.

Love the new kernel would u consider an overlook version? Eugene 1256 is so snappy but it corrupts data. That speed plus voodoo is crazy fast. Real 2000 + quadrant.

Froyo Kernel on Eclair?
ttabbal,
I did not know that a Froyo kernel could be backward compatible to Eclair. Is that the case, given that your Dragon 2.0 incorporating Voodoo 5 Stable will work with Bionix Fusion?
Please help me to understand this.
More to the point, I am on Bionix 1.9.1. Would Dragon 2.0 w/Voodoo 5 Stable work on my setup?
Thanks,
Bruce

Would love to use this, however i cant seem to get anything to install from the market no matter what i do. My TitaniumBackup restores just fine(apps only). Ive ODIN'd back to JFD twice but still nada. Ill try starting from JI6 and see if it helps.

So I'm running ttabbal's latest kernel, 2.0, and just ran a quadrant. It gets 1564 as the score. Now, this isn't just from voodoo alone, he's done a few speed tweaked which will bump up the score. But it's snappy as hell.
"if you amplify everything, nothing is heard"

Just put this in my phone and its works fine I'm running axura 2.1 works fine but u will see a second boot up screen the benchmark test is not that high I got in the 2500 with the oclf inthe market download but can't do that one anymore it tells me I have one installed already but over all its smooth

Don't worry about benchmarks, they are easy to fool in a high level system like Android. Cyanogen managed to get something stupid like 10k out of Quadrant.
This setup isn't for being a benchmark queen. It's targeted at a couple things I deem important. Multitasking smoothness/performance, and a test of direct-to-ext4 install. The no-wipe voodoo kernel is really intended to be used as part of the whole, but like I said, it should work with any froyo. Note: NOT ECLAIR. If there is more demand for an eclair version, I'll consider updating my eclair ramdisk as well.
As for the market, couldn't say. It's NOT the rom/kernel though. The market is a finicky thing and sometimes just doesn't work. It's usually the server side or the app itself that has an issue though. There's also an update to Market for Froyo, it seems to be more stable. You should get it downloaded automatically after running for a while. To check, look at an app description, you should have a new tab "Related".
When I've had market problems, I fire up my Wife's G2 on a stock rom (not even root) and she does too, so it's not anything I, or anyone other than Google, can control.

Does anyone know whether the Dragon Kernel that works with any Froyo ROM available from the OP supports use of a BootAnimation.zip?
UPDATE: Thanks geoffcorey for the info!
Tried on Axura 2.1 with larger nand. Flashed, rebooted, converted with no issues and is running very well so far. Haven't been successful getting Voodoo to run before now.
Thanks to TW, ttabbal, Supercurio, et al.

So I can flash this kernel over my setup on Axura 2.1 and it'll move everything over? What are the dangers? If for some reason it didn't boot up is there a way to recover without Odin?

I did this very thing in my post #16 above yours. Go for it! Remove any other lag fixes you may have though. I had none installed so I didn't have to do that. PERFORM A NANDROID backup and optionally copy to a computer before flashing the kernel to be safe. Restoring the Nandroid backup won't restore the kernel though.
The dangers are minimal if you backup. Permanently bricking the phone is unlikely. You may soft brick but you probably won't. PLUG IN AND DON'T TURN OFF THE PHONE UNTIL THE "TW" LOGO DISAPPEARS! Around this time, you will hear a voice say voodoo has been activated.
I believe the conversion process may attempt to revert the changes it tried to make in the event of an unsuccessful conversion. If reversion is successful then you should again have access to CWM to flash back to any rom you have stored on your phone. Use nandroid to restore your data and your back to normal.

Can anyone pm me a froyo captivate dump.

Hi I have made a rom for the i9000 called ULTIMATE. look at my threads and you will find it, I was wondering if captivate users will also like it, if so pm me a clockwork dump of a froyo rom. Basically do a nandroid backup of your phone, then connect your phone to your PC and in your SD card, go to clockwork>backup. There will be a folder with today's or whenever's date and pm me cache.img and system.img inside that folder. Have a good day

I think the Cognition roms are built on the JI6 which is a Captivate rom.
Not certain though.

Both the JI6 and JJ4 based roms are for the Captivate. Neither one uses a reorient kernel.

he's not asking for a froyo source; he's asking for a froyo dump. this includes JI6 and JJ4. I'd do it myself but I'm not at a computer :/

No one is going to "upgrade" to an old/slow/beta build of froyo when the official 2.2.1 jpx build is out for the i9000.

I certainly wouldn't use a captivate rom. I was thrilled when the reorient kernels made it possible to use the i9000 roms and totally get away from the att crap

Have you tried jpx? Its smoother and faster than any previous froyo build and i'm not even running a lagfix, still running on rfs, try doing that on jj4.
I urge you to try it, you will not believe how fast it runs, plus the browser is gpu accelerated in 2.2.1 pages scroll as smooth as butter, goto www.anandtech.com right now on your jj4 build and see how badly it lags even with flash disabled.
Don't hold your phone back with a 2 month old build, getting jpx to run our phones is pretty simple you just need to add a kernel/modem/sdcard fix, but if webstar1 packages all up in one zip it'll be even simpler.
webstar1: after adding either xcal's or setiron's kernel, add either the jk4 or jl3 modem and hardcore's sdcard fix then it'll work perfectly on the captivates.

+1 for the 2.2.1 usage. These roms are blazing w/o lagfix. The browser is just a pleasure to use.
Sent from my GT-I9000

i'm not on JJ4, nor have I been in a very long time. my only point is, and has been since I first posted in this thread, that it's not a dead build.

I just went back to the optimized JJ4 rom on my phone (from Cyanogenmod Beta 4 nightly). I've been on Perception and Cognition. While I haven't tried the 2.2.1 rom, I am perfectly happy with using an "old" outdated rom that was designed for my phone as every I9000 rom that I have tried otherwise has had some sort of little caveat that made it less desirable for me.
Maybe I just haven't tried the right roms, but I can't be the only one who would rather use a rom either designed from a Captivate rom or AOSP.

[Q] After flashing Cognition 3.04 my phone seems slower?

It was my first ROM flash, and along with it i decided to get the gingerbread keyboard, too. I noticed that my captivate seems slower in general now. Screen transitions and stuff like that is fine, but opening apps is usually slower. Like the phone lags a lot. I have it OCLF'd. At least, i did before flashing. It seems to not have erased it.
Can anyone tell me what the sudden slowdown is about? Am i just paranoid?
thanks in advance.

You should not attempt to have two lag fixes. Cognition has voodoo lag fix built in. I would recommend you flash back to stock and then flash Cognition.

Go back to stock and flash Andromeda 1.1 or 2.1. I've tried many ROMs including that one and nothing matches the speed of Andromeda. I highly recommend it!

Did you disable olcf before flash? If not flash stock start over. Any one who says rom x is best is saying a personal opinion, not fact

I haven't tried any of the other rom but you are right about the speed.... I get zero lag... I'm really impressed with this rom that I have no plans on changing.

Cog is a good ROM but by no means the fastest one out there. Serendipty, Phoenix, Paragon, Andromeda will all give you a much faster / smoother experience.

Be careful when flashing Andromeda because I soft-bricked my phone for 3 days, now I can't even use unless I am somewhere with at least 3-4 bars. I might have screwed it up when I flashed it.
