Alright, so I've been rooting phones for about a year now, but I have zero experience with the Fascinate (have worked on Eris and DInc before now) and my buddy wants me to help him root his phone. I've been reading for a while now, and there's one thing I haven't been able to figure out.
What is the deal with Voodoo? Is there an appreciable difference in performance between a non-Voodoo and a Voodoo kernel? Are there drawbacks to either?
Thanks in advance for any help.
Voodoo is code that is developed by supercurio. There are many branches of voodoo, including color, sound, and lagfix. Each aims to improve upon what Samsung has given us.
Color improves the color contrast of your screen if it is too blue or too red.
Sound is a fix that utilizes the driver inside of our phones to improve gain and give us new options
Lagfix converts all partitions from samsung's rfs file system format to ext4 and yields speed benefits
I am not 100% that my terminology is correct. Please correct me if anybody sees something is wrong.

IMO, voodoo is the only way to go. It is an overall improvement of your phone experience.

So Voodoo kernels contain one or more of these fixes?
Voodoo is basically the conversion of Samsung's RFS file system used in the Galaxy S phones to the more native EXT4 file system.
It also contains improvements such as color, sound, and such.

Nice. Thanks for the info guys.
So are there any drawbacks to using a voodoo kernel?

The only drawback that I have found is that given the slim amount of ROMs we posses here in the Fascinate community.... running a voodoo kernel can limit that a little more.
Also usually when updates roll out from source voodoo takes a little longer to come out.
But in all honesty there is very little in the way of drawbacks. Plus if you don't like it? Flash a regular kernel!
With the recent editions of Voodoo Color and Sound I would see even less reason to not use it.

I am still trying to learn more about Voodoo Lag Fix before I download the Obsidian V3 w/ Voodoo Lag Fix (Team Whiskey).
I can't seem to find the thread about it explaining in greater detail what it is different between this fix over the other one (OCLF)
Yes, I know they are two different lag fixes, but would like to know more about the Voodoo Lag Fix in greater detail.
- I know that OCLF uses ext 2 and Voodoo uses ext 4
- I know that IT IS A MUST to disable Voodoo BEFORE flashing other ROM's
- I learned that in some people's opinion Voodoo is better than OCLF, vice versa
(These are the basic things that I know so far.)
Guess what I am trying to ask is what are the pros and cons of the Voodoo Lag Fix. (Everything explained in greater detail would be great.. just can't seem to find the thread or sticky on this topic.) Sorry if it seems that I haven't searched hard enough; I'm just sick of reading about which is better than the other ones.
Bump... are there none?
OCLF creates like a buffer between the normal filesystem and the OS. So the phone still uses RFS (the crappy Samsung filesystem), but through the buffer of ext2.
Voodoo actually converts the filesystem from RFS to ext4, and does not have a buffer of any kind.
OCLF may get better Quadrant scores, but Voodoo (or even better, z4mod) are much better for real-world usage.
so how would I go about disabling it if I ever have to reflash the phone? also, would the voodoo lagfix be better for battery life or no?
I don't really think either one affects battery life much. I get great battery life with on my phone that has Voodoo.
And to disable Voodoo, you just put a file called Disable Lagfix on in the Voodoo folder on your phone and reboot. Rebooting when enabling or disabling Voodoo can take a while, since it has to convert the filesystem back and forth.
Try browsing around the Project Voodoo site for more info.
alright I will take a look at the read! Thanks for the help!!
moved to main forum
I was browsing some other site when I noticed some members mentioning how android 2.2.1 on their galaxy s devices made a HUGE improvement in overall speed, basically making it stock lag free. They had the original i9000 galaxy.
The story was, when google released android 2.2, their main goal was efficiency and speed overall but mainly for the snapdragon processor devices especially since their own device(nexus 1) + many others at the time, evo, incredible, etc. were snapdragon powered. Thus, people noticed the increase in speeds and also their benchmarks increased dramatically as well. The downside was, those optimizations kind of slowed down our hummingbird devices in some ways resulting in the lag we know of. Thats why some people feel(including myself) stock 2.1 was pretty slick in basic functions.
But since the 2.2.1 was leaked, people installed them on the international galaxy s devices, and even some ports were made for the samsung Captivate. All of those devices with the updates are much faster. I tried to find people having 2.2.1 on the Vibrant, but no know has so thus far. So does anyone know of any developments on 2.2.1 for or vibrants, or atleast somehow we can try to have it ported. I mean if they got it working from the i9000 to captivate, im sure vibrant should not be that much more different..
Just install voodoo lag fix. Will speed up your vibrant and be mostly lag free. Why wait for all that. I'm using odex uvjl4 froyo stock rom with voodoo. Runs awesome.

Because whichever way you look at the RFS, it is still FAT based filesystem, inefficient and ancient, Voodoo converts that to a proper linux based filesystem that should've been on the phone from the get go.
Voodoo lag fix is the ultimate solution to the lag problem. 2.2.1. in combination with voodoo would make our devices that much better with increased cpu and file system performance over 2.2.
2.2.1 was ported to the Vibrant already. Heathen got everything working and it was amazing EXCEPT for a major bug. The phone would restart every time it picked up too much network strength signal (service bars). They tried fixing it for weeks but ultimately no one was able to fix this bug which is hiding somewhere in the radio of the Vibrant apparently. Ultimately 2.2.1 was dropped and development for it is now halted.
I believe there is some development for 2.3 (Gingerbread) from both TW, CM, and maybe Heathen as well but it appears it is still a bit too early to have daily-driver ROMs.
I hope this explains the situation.
Voodoo brought my vibrant a 1000 points higher on quadrant benchmark, everything is so much better, stop being a little biznatch xriderx66

The OP is asking for like updates that improve speed and everyone goes VOODOOO!
I understand, I use voodoo too, and to the other guy explaining to me about RFS, I know that already lol.
Thanks for the advice, but actually i already have voodoo running. Its just that I was interested in finding a more stable option, especially something that did not require having an additonal install. BTW how come people are getting such great benchmark numbers with their voodoo vibrants. I was getting close to 1400 and just did a complete wipe and reinstall and now im getting about about 1000. Regardless of the numbers, the phone seems to be flying though, regardless of the bogus numbers..

make sure your /system, /data, /dbdata and /cache are ext4, you can check with adb shell or terminal emulator app via "mount" command.

Any hope heathen's work might be usefull for porting to the Mobiulicity sold T499 Dart?
any chance of a build from heathean to test on mt dart?
ive tested pretty much all the kernels that xda has to offer, and i'm still bouncing back an forth between CWkernel and Tigers Blood FPScapped.
I'm one of those unfortunate souls that have a Vibrant that doesn't like the FPS being uncapped...and it gives me the shaky screen thing upon boot. No Bueno.
I just want a kernel with good performance, BLN, Voodoo Sound and color, and reasonable battery life. CWkernel provides this, but doesn't seem as smooth as tigers blood...plus Jocelyn no longer supports it.
with tigers blood, i get more of a battery drain than CWK.
I would also like a less invasive Kernel Screen like the B&W "google" that Jocelyn has put in CWkernel.
I would do it myself, given the knowledge....
Could someone point me in the right direction as far as compiling my own kernel? or at least suggest one other than the two described above?
Thanks!
To clarify, are you just looking for a guide to compile a kernel? Or do you need a guide which includes instructions for applying Voodoo, BLN, etc. and then compiling a kernel?

Ive just used overstock and bali kernel but I didnt saw that on the descriptions (or dont remember)
Give the Bullet Kernels a try. I think you will be intrigued by the raw speed and good battery performance.
So I'm sure the title makes this clear already, but I have an HTC Incredible as of now, but am preparing to trade for a Fascinate. From what I've gathered online, the Fascinate has the Incredible beat on hardware (except for the camera), but isn't quite up to par on software (TW vs Sense, Bing, just got Froyo, etc), but for a CM/AOSP guy, that's not too big of a problem.
So, I just have a few questions as I prepare to make the transition.
With the DInc, pretty much everything can be done on the phone after the one-click root with unrEVOked. It's to my understanding that much of what has to be done is in Odin? The concept of going through another technological medium to accomplish something on my phone is going to be a bit new for me, but I catch on really quickly, so I'm not too worried.
Are there any tricks or tips/helpful reading material that anyone could suggest as I settle in over here?
As I looked through the Dev section (however briefly), it seemed like Kaoscinator was the most stable GB rom available on the Fascinate. If this is not true, which is? I'm not a fan of MIUI, and tend to like stock GB (or as close as possible) the best, so this would really be my biggest question.
Thanks!
The stickies in the General section should get you off to a running start. As for CM/Aosp builds, JT's CM7, currently test build 5, is the most stable and functional at this time.
i would suggest ComRom, most AOSP like in that it doesn't have TW, but everything works, give CM a alittle time, it will be perfect when 100% working...but also know that OMFGB and OMGB will be ported soon, r2doesinc is on the case, and they are working on that atm...
I ended up going through ComRom to get to the CM7 alpha/beta/whatever it's being called. It's pretty stable, I was pleased with it. I needed me some real AOSP though (modded AOSP, but you get the point). The only issue I've had so far was the random ringing, but that disappeared after someone called me before I had the chance to reboot. Haven't had it since.
I was having problems using RM to flash a recovery, but that's because there was a step that I was skipping... Odin. If my bootloader had security disabled, S-Off, I could completely unroot, and go from pure stock to a rooted Rom in the time it takes to make a Nandroid, wipe, flash and boot. Being able to flash a recovery image through the bootloader on the phone is really the only thing I miss from the Incredible other than tthe optical trackpad. I'm loving the screen size, and everything else. The processor on this phone is fantastic. I can't wait to see what springs up in the development forum once the CM team officially supports this device. Especially some OC kernels... this thing could go even faster, I can feel it.
OMFGB will be a welcome addition as well. R2 and his team do great work!
I'm still learning things and establishing procedure, but if anyone could point me to some plain as day information on what exactly Voodoo is, that'd be great. That's not something I've ever heard of until now.
Thanks for the patience! I catch on quick, I promise I don't ask a whole lot of questions, as I try to figure it out on my own first, the switch is just a little daunting with the addition of Odin. Weird stuff.
Voodoo is comprised of a few parts.
Voodoo lagfix-- converts the file system from RFS to the speedier ext4. This improves the responsiveness of the phone
Voodoo Color-- makes the colors of the phone "pop" more and look better.
Voodoo sound-- The galaxy S series of phones have a VERY good audio chip. Voodoo sound lets you fully take advantage of the processor's power. Hook this phone up to a decent receiver and speaks and you will be pleasantly surprised.
Voodoo sound and color REQUIRE kernel source code to be baked in. Voodoo lagfix does not require kernel source. Thus, you can have voodoo lagfix without color/sound (and potentially vice-versa).
Aha! The Fascinate's partitions ARE Ext4 (except for non-Voodoo, of course)! I thought so! The partitions were all Ext3 on the DInc. That's pretty cool!
Now, how would one control Voodoo? Is there an app that does that, or is this controlled via the Voodoo Settings in the Lag-Fix Recovery?
Sound is controlled with voodoo control app in the market. Lagfix is controlled by clockwork. Color is just built into the kernel and has no setting options
Voodoo color only works when you have your backlight set to max brightness... unless I am mistaken

You are correct...its to help balance the colors to remove the blue tint of bright white display due to its pentile design

Yup, I just found that exact kernel. I stumble into something new every time I go through the Dev forum. I'm definitely digging this phone.
I like the custom kernels but the voodoo conversion seems to do more harm than good sometimes, are there any cons to just not converting it?
Currently the difference is more placebo than real gain. My suggestion is to clear cache/dalvik and try out stock kernel for a few days, then try a voodoo kernel and compare them day 1/1 day 2/2 etc. I decided to stick with the stock kernel since it was working fine for me and it didn't mess up my screen with that voodoo color crap.
Are you referring to the voodoo lagfix?
No, there's no cons to not using it. I find my phone actually works better with it off.
The only con is that your phone is gonna run slower than it would if it had voodoo on it, also your gonna have a lower quadrant score, but that doesnt really mean anythinng. i dont recommend voodoo lagfix, but i do recommend voodoo sound
Aye, I've been running without the lagfix enabled for a while and I don't really regret it. Much less hassle for a flash-aholic.

I had better results with lagfix disabled on tks kernal aswell. I really dont think ext4 is any faster than rfs on gb... now on froyo roms I noticed more of a difference...couldnt tell you why.
