Installed this over my JP6 with Tatuyama's rom. I removed OCLF first.

Worked a charm. Quadrant score of 1356, substantially lower than the 1500 or so I was getting with OCLF, and the 4/4 i/o database writes does take a few moments but overall, on first impression, seems lightning quick in comparison to OCLF before.

Let's see how it goes but it didn't wipe anything of mine (whereas voodoo on 2.1 did!) and seems to be smooth and quick!
[Galaxy S I9000 Android Development] Ganfas:
thanks

and ty for the voodoo, first time trying it, and already impressed with your work. Many Thanks =D

So is it safe to use voodoo over tayutama rom?

What about the root - busybox - cwm?

Does Voodoo improve web browser performance (scrolling, zooming and/or web page loading) ?

I couldn't find any info when doing a search.
[Galaxy S I9000 Android Development] RyanZA:

The performance difference is a lot for writing files. This is a unique characteristic of MoviNAND (and similar flash). Depending on usage this may not be an issue, but using applications that cause numerous database writes (such as a twitter app) will have far worse performance.

This isn't completely true. See here: http://en.wikipedia.org/wiki/Flash_memory#Block_erasure

Even writing a single byte to a file can cause the entire block to be erased and rewritten. So you can't count MB usage as 'wear' on the device, you must count it in number of writes. Since a journal can be written for each file operation on EXT4, you are potentially causing two 'erase' commands to be sent to NAND. The SGS MoviNAND block size appears to be 1MB-4MB in size.

A simple Open File -> Change one byte -> Close File -> File sync can possibly be causing as much as 8MB of data to be written to flash.

BTW, your attempts to insult me are particularly humorous. Please continue! :D
[Galaxy S I9000 Android Development] supercurio:
Okay I took note of the few install fails, i'll see that tomorrow.

Prepare your logs guys, and see ya !
[Galaxy S I9000 Android Development] AV1985:
My phone had that CFroot with CWM recovery installed too and voodoo has set up fine. I haven't tried getting back into recovery yet. Hold on...

Standard recovery 3e is fine check.

Couldn't get into CWM unfortunately or 2e.

No it don't.

@SuperCurio -> You're the man! Some money coming your way soon..

Coming from JPK, installed Doc's RomMod Froyo V2 (JPA-base) and then installed Voodoo over it and the phone is flying..

Installed/restored about 45 apps in no time (the quadrant score is 1595), but have never felt the phone this smooth and amazing before..

Voodoo rocks!
[Galaxy S I9000 Android Development] d.fx:
phone not fully rooted (or something else...)

supercurio , sorry to bother , but i seem to have a root issue , is there multiple levels of root access? cause i could grand root acess to titanium , but not to root explorer or quickboot for example . i flashed voodoo on a clean JPM install and installed superuser from market , am i doing something wrong?
[Galaxy S I9000 Android Development] mocro:
if i flash a new rom do i need to install voodoo again?
[Galaxy S I9000 Android Development] supercurio:
By the way, Voodoo lagfix use adequate and performance-tuned Ext4 mount options.

Which means that every benchmark done without these optimized mount options are useless (refereed to Voodoo Ext4 performance)

As usual, it's all in the source.

http://github.com/project-voodoo/lagfix/blob/froyo-dev/voodoo_ramdisk_parts/scripts/init.sh#L63

I already informed other developers around #project-voodoo about these mount options (and why), to help having more high performance but still with security solutions out there (z4ziggy, atinm.. every twitter folower.. ;)

PS: without these tuned mount options, Quadrant benmark result is the same between Ext4 and RFS.

But of course the usage experience is night and day anyway.
[Galaxy S I9000 Android Development] supercurio:
If this Rom contains a kernel, yes.
[Galaxy S I9000 Android Development] AV1985:
Yeah, my quadrant is now checking in at around 1150 but the performance is much better than OCLF which was around 1600. Isn't 1150 ridiculously low?!
[Galaxy S I9000 Android Development] supercurio:
Yes currently su is only in /sbin but a few (not very smart ^^) apps search specifically /system/xbin/su

I'll install it carefully in next versions.
[Galaxy S I9000 Android Development] supercurio:
The current Froyo build tend to give some random high/low result. If you're unhappy with it, just re-run it ^^

The standard is around 1500.

But as you know it's just a number, the only thing that matter is your user experience.
[Galaxy S I9000 Android Development] mpvc_toadie:
Just flashed actual voodoo to my JPM Galaxy- works like a dream, thanx a lot supercurio.

Runs smoother than OCLF i think...!

Thanx!!!
[Galaxy S I9000 Android Development] meisterlampe2000:
and that experience is simply awesome.coming from a sapphire the i9000 was just another league...then the upgrade to Jpm made it even better.now,with voodoo we reach a performance increase that syncs this powerful hardware! very good jobject man! thank you
[Galaxy S I9000 Android Development] _JKay_:
I just used odin 1.3 and flashed v5 pre3 on my I9000 JP6.

The flash went ok and the phone booted without converting anything.

I realised that I had a folder called Voodoo with a folder inside called disable-lagfix_NOT

I removed these folder and rebooted

Now my phone keeps rebooting in a loop over and over again with the robot girl saying convert again and again :-(

Ill try and reflash it again...

EDIT:

1. I tried reflashed the voodoo v5 pre3 kernel tar using odin. Flash went ok but same problem. Rebooting after robo girl saying converting.

2: Then I flashed the original JP6 kernel again and I think I got my old and slow phone back...

3: Success!! I reflashed JP6, did a factory reset then voodoo5 pre3 flashed... ext4 conversion completed in seconds...

Now Questions:

1) Why didnt it work at first: was only rooted and had the battery mod from rom-g version2..... hmm....

2) Now how to I get Root Explorer, SGS tools, AutoKiller etc to work... TitaniumBackup, mount /system (rw/ro) and Better Terminal seems to get root access just fine.... can I just copy it? to be continued...
[Galaxy S I9000 Android Development] mike.sw:
is it me or the web site crashed?
[Galaxy S I9000 Android Development] shrooms90:
What roiting method should i use for voodo lag fix? Im running on jp6 and i flashed a kernel to get root so i think root access will be gone if i do this lag fix or am i wrong?
[Galaxy S I9000 Android Development] AV1985:
If I re-run voodoo pre3 on top of the already installed voodoo pre3, you think it'll be ok, or should I remove it first?

You're right, it's just a number but it feels oh so awesome to see the number flying at 2000+! Right now, and just did another quadrant test, down to 931. It's gone from 1500, to 1300, to 1100 to 900. I'm concerned that it keeps dropping, advice? What happens when it gets to 0? :-/
[Galaxy S I9000 Android Development] EarlZ:
The robot voice says conversion success but I get a black screen after the Galaxy S logo boot animation.. Is there a way I can make my phone boot properly back up again coz I havent backed up my inbox and I have a few important msgs in there..
[Galaxy S I9000 Android Development] AV1985:
Ok I know why it went to 900 before - because my battery was low so setCPU underclocked my processor for me! Just stuck in the spare battery which is ok and quadrant is coming up as 1160. More reasonable though still low.
[Galaxy S I9000 Android Development] pele78:
I know this might sound strange but you should remove it. I just had deja vu!
[Galaxy S I9000 Android Development] mike.sw:
just tested on JPA, removed OCLF first (just the lagfix, not the app). then flashed with odin.

works.

quadrant 1550~ in first try.

looks good, can't compare to oclf yet.
[Galaxy S I9000 Android Development] herrfischer:
very nice to hear. since i don't want to root i will wait .. patiently ... :)

[Galaxy S I9000 Android Development] kenkiller:
Guys, besides thanking supercurio, do take the effort to report Ryanza for trolling in this thread. It's really pathetic what he's trying to do in this thread, regardless of how much he's contributed to this forum. It doesn't give him an excuse to keep making snide remarks just because Voodoo lagfix is the more preferred and popular lagfix. :(
[Galaxy S I9000 Android Development] Mycorrhiza:
Finally got it to work, after numerous strange and outright annoying errors...

On Tatuyamas Superlite I am getting 1600 and It feels much faster than anything before.

I got ~2000 with OCLF, but this feels smother.

I will give my second opinion once I restored my apps.
[Galaxy S I9000 Android Development] fuze_freak:
I notice that on the boot screen were it says galaxy s gt-i9000 (not boot animation)

the screen flashes like a tv distortion

any advice ?

[Galaxy S I9000 Android Development] :
Supercurio, there's something worth a few pints coming to your Paypal account..

I sincerely hope that you earn more from this project -or should it be Project?- than the Samsung tech who looked into the lag-problem for 15 minutes.
[Galaxy S I9000 Android Development] EarlZ:
Same here........................

EDIT:

Also it doesnt seem to be compatible with the JP6-JPM hybrid ( http://xdaforums.com/showthread.php?t=796987 ) Firmware as it always gets stuck after the boot animation.
[Galaxy S I9000 Android Development] pele78:
Awww Ryan is still much a major player in lagfixes, I don't mind the comments he makes, its no different from what windows, apple, google, linux etc do.... Its called business as usual.

I'm not taking sides, but....I'm still much of a oclf fan because of its ease and simple installation without that linux type gossip and jargon lol.... I'm still waiting for some kind of beginners guide to this voodoo....

[Galaxy S I9000 Android Development] nexus0_1:
That will be fixed in beta/final release, i'm sure

@ Jeshter2000: Just install superuser (and busybox) apk from market, that's all you have to do

by mistake I installed the root from chain now after the boot animation all I see is black screen do I have to reinstall all the system again ?
[Galaxy S I9000 Android Development] Psychotoxic:
You already have root. Just install Superuser from the market. Root is included in Voodoo Kernel.
[Galaxy S I9000 Android Development] Syb3r:
Just to be sure. It doesnt matter if my jp6 is already rooted (woth superoneclick) right?
[Galaxy S I9000 Android Development] zilvesta123:
Great work. I've got a question though, should I remove the ''Voodoo'' folder of my internal SD before installing this Froyo Voodoo? I already disabled it with the ''disable-lagfix'' folder.
[Galaxy S I9000 Android Development] CazeW:
For someone reason I didn't get it to work though. Had to use SuperOneClick to get root working.

[Galaxy S I9000 Android Development] Mycorrhiza:
It may not be the easiest way, but this one worked for me in order to get root (I had the same problem some people are mentioning)

Flash JPM (I guess JP6 should work, too)

obtain root in any way (I did it by flashing CF Root 1.2

Install a custom pre-rooted Rom (I used Tatuyamas)

Flash Voodoo

If this fails too, try flashing CF Root again, although it could be that it messes up Voodoo
[Galaxy S I9000 Android Development] NeoXTC:
Titanium backup not been granted root. Works before the voodoo fix. Pretty sure it's related to other root problems people are having. Oh well not required for it yet and voodoo payoff is good so I'm sticking with it :)

I have JP6 and I've used the CF-Root. Is it ok to install voodoo pre3 over CF? I understand I'll lose the 2e recovery and I can live with that but I'd rather not have to do a complete flash if Voodoo breaks the phone.

Reboot

If you want to use titanium then download busybox by clicking on the :

Curio..

I found a bug, not that it's a big problem but when i bootup my phone and the samsung Galaxy S stuff/logo pops up after a couple of seconds i get a flash of red/green crashlike stripes trough my screen and just in a flash it goes back to it's normal state. I have Pre3 installed..

Another thing is, after some speculations in this thread i tought you added root acces in this pre3 release so i installed superuser to try it out. After i installed it i rebooted my phone. But my phone could not boot all widgets some crashed or something so i have to delete them and ad them again. Not a big problem but i tought you should know.

[Galaxy S I9000 Android Development] Tyvesto:
Works well on Galaxy S JPM !

I had JPM + OCLF + Root (from CF) and removed OCLF to flash with voodoo pre3. I still have root after the voodoo flash with odin.

Voodoo pre3 seems smoother than OCLF, although I had a higher Quadrant score (1900 with JPM+OCLF, 1500 with JPM+Voodoo pre3) , it's quite strange isnt it ?
[Galaxy S I9000 Android Development] Rawat:
OCLF bypasses the I/O tests in Quadrant, scoring the highest score for it due to the loopback system in place.
[Galaxy S I9000 Android Development] Anton2079:
Works on JP6

Very smooth!

Thank you
[Galaxy S I9000 Android Development] Ferdimage:
working beautiful on JPM :) you were right no major difference from Ext2 zmod in terms of speed very similar, but i rather the etx4 for data safety and also your color tweaks,

for the color profile for videos, is your tweaks set on the "Normal" Color tone settings by default?
[Galaxy S I9000 Android Development] zenkinz:
oh in which case I like to wait for your next release because I need the recovery to apply the theme update.zip. Or can I apply it first and then follow by flashing your kernel?

edit:

decided to take the bait as the voodoo lure is too tempting to resist. I do a clean firmware flash instead, but apply CF root kernel so that I can apply the update.zip for the theme update. Then after that I flash voodoo pre-3 kernel and the whole setup is seamless! I like the voice commands to inform me of the various stages, and it was so cool! ;) First impression is that it's quite fast if not faster than z4mod. However, as I'm setting up the google & exchange accounts, I noticed there's a few milliseconds lag in the keyboard showing up when I try to type in my account details. Not sure if its due to the multiple concurrent data task which I know would lag the phone, but I will monitor further.

just be patient.....Voodoo with 2e or CWM coming in an update.
[Galaxy S I9000 Android Development] zenkinz:
if you can't wait for the next release of voodoo which should have recovery 2e, you can do what I did.

flash the firmware and custom kernel that supports recovery 2e (e.g. CF root kernel), apply update.zip for whatever update you need.

then flash voodoo pre-3.

[Galaxy S I9000 Android Development] aroy002:
hey guys, just wondering why voodoo+ froyo seems to be scoring lower in quadrant than 2.1 ( i know benchmarks don't really matter), but running quadrant advanced, i've seen videos showing the cpu score to be around 1500 (instead of 800 on eclair). Does the IO part no longer score in the 5000+ range?

Does it have to do with optimizations to be done with voodoo, or some code now implemented in this version to make it work with froyo?

On eclair with voodoo, i score around 1700, and close to 2k when the kernel is overclocked to 1.2.

Just super-curious is all, thanks.

See what I did there?
[Galaxy S I9000 Android Development] mathieumeuh:
Using launcher pro too. It was amazing with oclf and now with voodoo, that's still great, but maybe a little bit slower.
[Galaxy S I9000 Android Development] m4ssnet:
i confirm me too that the scrolling of apps installed with the launcher is still laggy...

I Tried launcherpro and adw, both laggish !

ADW much more than launcherpro...

But, if you set 4 icon in the column (altought 5 that i usually set), into launcherpro disappear almost completely the lag !! try it... really don't know why

I think, samsung in 2.2 official have left some bugs behind that issue... :mad:
