I don't think you're supposed to use the recovery to partition your sd. I know the Voodoo Recovery isn't exactly the same as Clockwork but you might want to try the solutions here.

Stock JL4 w/ Voodoo 5 Kernel: Performance Result

Well, my Hummingbird is now humming on Froyo w/ JL4 + Voodoo!

Metrics:

Stock JL4 Pre-Voodoo: Quadrant = ~1000; Linpack = 14.

Stock JL4 w/ Voodoo 5: Quadrant = 1525-1600; Linpack = 14

Comparing Quadrant CPU scores between Eclair and Froyo, I have noticed that Froyo appears to be more optimized than Eclair, even though it is bulkier.

And, of course, the 50% increase in overall Quadrant score between stock JL4 kernel and Voodoo is due to the dramatically increased I/O sub-score resulting from the Voodoo magic sprinkled over the filesystem.

The Linpack score is largely unaffected by Voodoo because Linpack is a measure of processor performance (number of floating-point operations per second "flops"); because Voodoo addresses the filesystem I/O and not processor performance. In fact, Linpack caches its operations in RAM specifically to avoid the problem of I/O entering the picture.

By comparison (for the curious), check out these Linpack scores:

Samsung Galaxy S: ~14 MFLOPS (10^6).

Nvidia GeForce GTX 480 ("Fermi" series video cards w/512 processors): 1.3 TFLOPS. (Yes, that is tera-FLOPS! (10^12)) (Available on a graphics card for $1,000+)

National University of Defense Technology, Tianjin, China; overtook US/Japanese dominance (oops!) last month (November 2010) as the fastest supercomputer in the world, with 14,336 6-core Intel Xeon processors plus 7,168 of the Nvidia GeForce processors (above): 2.6 peta-FLOPS (10^15). That is roughly one billion times faster than our cell phones. :eek: (Of course, it probably cost about $1B more than our cell phones, too.) :p

Just FYI, lest anyone get too cocky about his/her cell phone. :D

And no, these metrics are not "meaningless," as smartphone urban legend goes. They mean just what the say they mean, except in the case where the filesystem control reports to Quadrant that an I/O operation is complete when it really is not, as is the case with some write-back cached solutions such as ext:2 looped. What is meaningless, insofar as communicating results between people goes, are statements like "this ROM is blazingly fast" etc.

Be cautious of attempts to elevate the subjective over the objective where computers are concerned. Save that for poetry and literature. ;)

Noticed any improvement with Voodoo over the framework mods and script changes by TW?

Ok now can I get some feedback on something I read earlier in the thread? Does using this Voodoo kernel disable the mods TW put on the Nero? Is it a one or the other situation (therefore rendering the custom rom into a theme)?

If so is doing the "S_" delete what allows you to use TW's modifications in tandem with the ext4 partitioning?
[Vibrant Android Development] Whitehawkx:
Voodoo makes Nero even smoother. You are correct that flashing Voodoo does "disable" TW's custom init scripts. The good news is that the voodoo kernels can still call scripts from init.d; they just can't read the S_ prefix. Just like you said, if you just simply remove the S_ prefix from the scripts in /system/ect/init.d and reboot then they will all work again. So in the end you aren't losing anything but gaining Voodoo smoothness. :)
[Vibrant Android Development] kponti:
By any chance a lil more detail on how to do this? Step by step will be great if possible lol

EDIT: Didnt read your message completely, answer was right here all along.

So using Root Explorer I found the files. All I need to do is simply rename them without the "S_" right?
[Vibrant Android Development] kponti:
Finally on another note, I disabled Voodoo and installed Nero, to re-enable Voodoo I removed the unlagfix folder, do I have to reflash voodoo?

[Vibrant Android Development] smartmind:
Dear Supercurio, I have flashed your voodoo5 kernel and Eugene's Macnut R14 final，it's great experience but the quadrant scores are around 1300-1550.

I have learn from another thread post by you that by removing journaling of ex4, the scores could be higher than now. I try your suggestoins of that threads but failed to removed journaling of Voodoo 5 kernel.

I wonder if you could kindly make a Voodoo 5 kernel that has already been removed journaling of ex4?
[Vibrant Android Development] kponti:
If quadrant is your only reason for doing a lagfix, why dont you try the EXT2 lagfix? Doesnt do much of anything but will sure boost your score to over 2000. Voodoo from what I've seen, your number is right. Boosting the score via no journaling will give you no real world advantage or speed (except quadrant score)

Could you by any chance give me a quick step-by-step of how and in what order did you flash everything so I don't flash thing's on top of each other and screw myself over. Still new to flashing these roms and kernels ;(. Appreciate it!
[Vibrant Android Development] danger_duck:
Sure.

What I did in order:

1. Odin back to JFD (this is just a personal choice for me to make sure I am starting clean before flashing any ROM)

2. One click root t-mobile rom (again a personal choice, you can skip this and go straight onto 3)

3. Install and run Rom Manager (or after you have Odin'd to stock if you previously had CWM you can just reboot into Recovery and flash Nero)

4. Flash Nero v1

5. Follow sombionix's instructions for first boot of Nero.. So.. After first boot wait for 20 mins (for odexing to complete) then reboot.. then install all apps and change settings.. then leave for 5 mins then reboot

6. Then reboot into recovery and flash JL4 + voodoo

7. Boot and wait for voodoo to notify of completion then hey presto you're up and running

Obviously I've flashed JL4 but a safer option would be JL1 as this is what Nero v1 uses out of the box.

I also didn't bother re-naming the init scripts and have not noticed a single issue yet. But that may be something you want to do

Good Luck!
[Vibrant Android Development] OmniNut:
Thanks so much dude, very helpful! One last thing, when you say "then install apps and change settings" do you just mean you mess around with your phone to set it the way you want? Or do you mean there's actually settings(procedures) you need to follow? Thanks again!
[Vibrant Android Development] danger_duck:
Because I'm not actually with T-Mobile I had to setup my APN in order to enable a 3G connection and then changed my ringtone etc..

So yes, just set up the phone the way I want it and install the apps I actually use, I don't use Titanium Backup but if I did I would restore all my apps and settings before reboot.
[Vibrant Android Development] OmniNut:
Ahh alright well I'm t-mobile so ;). Going to start flashing everything now - will post my experience with this added to nero v1 !

Haptic feedback works if you flash jl4voodo. Running nero+jl4+super io. Thanks for any input
[Vibrant Android Development] smartmind:
Why after I flashed Voodoo JL4 with macnut r14, the phone info still says the baseband version is T959UVJL1? But the haptic vibration is back, when I flashed Voodoo JL1, there was no vibration, so this shows I have successfully flashed Voodoo JL4?
[Vibrant Android Development] andyjang8944:
I believe that you did flash JL4 but in settings, it might not say JL4 because I think it's only the modem not the kernel. I'm running Onyx 4.2 JK2 and I flashed JK6 Voodoo and everything works for me.

external sd card problem

It's strange that when I have flashed Voodoo JL4, my external sd card shows as a cd rome in computer if I plug my phone to pc and using usb connection. And tw's mounting fix doesn't work. I can copy out files from the " cd rome" but I can not write any files into it. I am using eugene's macnut r14 with voodoo JL4............

[Vibrant Android Development] Whitehawkx:
Removing journaling does increase your quadrant scores and makes things like loading web pages slightly faster. However, as Supercurio mentioned a few pages back by removing journaling you put your data at more risk for corruption. Corrupting your /data partition doesn't "hurt" your phone but if it does happen just means you'll lose current data and have to reinstall all your apps. If you do this I would advise against removing journaling from the /system partition because you want that to be 110% secure.

Edit: I have heard some ppl say that changing the to commit=60 increases the quadrant/speed as well. Currently I believe it it set at commit=5. What that means is if your phone shuts down or reboots for w/e reason you will only lose the last 5 seconds of saved data. So changing it means you could possibly lose the last 60 seconds of data. Not a huge deal imo and you keep journaling.

[Vibrant Android Development] jamesyl:
Do you know what changes TW made to init.d?
[Vibrant Android Development] BruceElliott:
That is true, because journaling takes some time. However, your phone will almost certainly become corrupted over time if you remove journaling, so why would your do that?

Did you set your voicemail carrier to your service provider? This is set under settings, call settings, voicemail. I noticed in the newest ginger clone which is jl4 based that google voice is a voicemail option in that menu, I haven't noticed that in any other previous roms/frameworks, and wonder if that may affect your notifications.

Thanks for your adives, I am a noob to this phone. Where can I change the commit?

Is this a kind of cheating Quadrant?

[Vibrant Android Development] BruceElliott:
What do you mean? My TMO voice mail indication (puzzle lock) works fine. In fact, under settings--->call settings--->Voicemail---> Voicemail service, my phone shows only one choice "carrier" because I have never set up google voice. You might try restoring green (ONLY!!!!)system app data from Titanium. (E.g., "Accounts," "Application Widgets," "Bluetooth Pairings," "Calendar Storage," "Contacts Storage," etc.) This is not guaranteed to work between major ROM releases (e.g., Eclair to Froyo), but it must have worked for me.

I managed to royally screw something up on my phone. Had to Odin Eugene's Froyo that doesn't brick to get me back into a usable state. Of course my interal SD would have to be wiped out and my last back up was from a couple of days again. No biggie. Going to start fresh with JL4 again and re-install my apps from Titanium. Going to check the voice mail thing again. If that works I'll add some voodoo magic.
[Vibrant Android Development] ljv:
Well, I finally got the stock_JI4_deodexed reflashed and it's up and running. I remembered under call settings that the only choice is carrier but it was never selected by default so I thought that was the problem. After selecting it, I still get no voicemail notfication. Tested this right after the fresh flash. No other apps installed.

Anyway, I don't want to clutter up this thread anymore about my voicemail problems because this thread is about Voodoo. My apologies. I'll just fall back to my trusty JI6+voodoo.

Notifications LED

BTW regarding notifications of all types:

NoLED from the Market is a too well-kept secret. It sends intermittant LED icons to the screen to provide notifications without pressing the power button!

I tested it on JL4; works great. Note these quirks:

(1) The key to good battery performance with this app is to use blink settings. There are three timers of interest here, blink "on" time, blink "off" time, and "dots moving time interval." I set on time to 1 second, which is enough for me to see the notification icon and time-of-day. I set off time to 8 seconds, which is long enough to conserve battery but short enough to see the notification again without waiting too long. Experiment. Set the "dot (icons) moving interval" to some long time (e.g., 60 seconds) so that the icons don't jump during the 1 second that you have to see them during the "on" time. This works with the exception of the second blink, when apparently the timer start-times cross for whatever reason.

(2) If you want this app to use a microscopic amount of power, set options to display dots instead of icons. In that case, though, you must remember the color that is associated with each notification type. For me that is a PITA and not worth the small battery savings.

(3) As you can see, this app allows very fine tuning for each user's battery-saving vs. readability performance. Outstanding! That said, I am going to ping the dev to request a 2-second on time. The option jumps from 1 second to 5 seconds. Two seconds would be ideal for my old eyes.

(4) Under "Miscellaneous," uncheck both "Use power button" and "Use back button" for dismissing notifications. Just press the power button to turn the screen on as usual; this is not laggy in JL4 (although it was in JI6).

Enjoy!

Edit: The power button is laggy only immediately after a re-boot. Otherwise not.
[Vibrant Android Development] BruceElliott:
It all works. You're gonna love it!;)

Do be careful when restoring from Titanium. DO NOT restore "all system data." Just restore "all apps with data" in batch mode. Then you might restore some system data items, but only data for the system apps showing in green. Probably best to avoid restoring system data even for apps in green that show "2.1".
[Vibrant Android Development] BruceElliott:
You might try (Froyo That Does Not Brick)---> Stock JFD--->JI6--->JL4. That is what I did, come to think of it.
