    Can i choose not to restore factory settings after this lagfix ? And also, after doing this lagfix , my phone does not seems to be rooted at all.

    Bartender…..get this man a drink…Hell….get him anything he wants. Neal…thank you so much for the step by step walk through. I no want to sing lullabies to my phone at night it runs soooo smooth and fast.

    One Question I have for you though……I didn’t do the clear cache step in the recovery mode. I didn’t want to do a factory reset which I seem to recall you mentioned to do. Is this bad? What benefits are there from doing it, and what will I be missing out on…..extra battery life? I did a quadrant test as scored a 2253!! for me…that was unheard of before!! I just was wondering if I could leave it the way it was.

    Cheers and thank you very much again. To anyone reading….don’t even think about doing it….just do it. Follow Neal’s explanation….and you will be a very happy androidaholic.

    Thanks for the good work Neal,

    I’m a little confused. Initially you said “Only JVP”, a week later “JVQ”, and a couple more weeks “JVR”. I have JVQ. Is it the same Voodoo lag fix for P, Q and R?

    • NeaL Pradeep

      August 16, 2011 at 12:19 am

    Actually I dont have at all installed voodo lagfix, what is your suggestion..
    Do I need lagfix installation for fw XXJVR 2.3.4 (currently from quadrant, full benchmark 1450-1700)
    if yes then, should I wait for updated voodoo lagfix version/ or there is another alternative to enable lagfix.
    Thank you

    • NeaL Pradeep

      August 5, 2011 at 12:59 pm

      no, its not required but we will try our level best if we come out with the procedure to Voodoo XXJVR laden SGS!

      I don’t even have kies in my laptop. I don’t need that any way. I can backup my files, contact and apps elsewhere and don’t depend on kies for firmware upgrade.
      just flash manually, why you need kies for upgrading to xxjvq?

    Hi,
    I couldn’t access recovery mode….

    Here’s what i did to my Galaxy S (Eclair):
    Flashed to Gingerbread XXJVP 2.3.4 Firmware, wiped cache partition & factory reset.
    It worked awesome.
    Wanted to make it faster hence Flashed with Voodoo lagfix as said on this page… but i forgot to kill the Kies processes. The process occured but my phone couldn’t start…. and the robotic voice kept saying wipe cache partition or something…
    So, i switched off by removing the battery and switched on the red recovery mode and managed to Wipe cache and factory reset, but the robotic voice came back to haunt me with the same message.
    I freaked out and entered download mode again and again flashed to XXJVP 2.3.4 Gingerbread…
    Phone switched on fine… but now i couldn’t enter recovery mode…
    I thought reflashing the Voodoo lag fix might fix it… but still can’t enter Recovery mode(download mode works fine)
    Overall phone is way better than before but just for the sake of procedure, i wish to access recovery mode and wipe cache partition and factory reset.

    • PVB

      July 15, 2011 at 2:07 pm

      Leave it.
      I added my Sim and could enter the recovery mode…..
      Wierd.

    hi Neal, thanks for the comprehensive overview of speeding up the phone. I havent done it yet as I need a few questions answered as there seems to be a number of “upgrades” and Im unsure which one I should do.
    My phone : GT-I9000, FrmWr 2.2, Baseband I9000HVJP3 , Kernel 2.6.32.9 root@SE-S604 #6 , Build nmbr FROYO.HVJP4
    So ALL applications get removed ? And Im with Vodafone. Does the startup screen with the VF logo disappear ?
    Look forward to your response and ALl help here appreciated.

    Hi,

    ive already rooted my phone with the latest gingerbread 2.3.4 XXJVQ Firmware.

    is it safe for me to install voodoo lagfix, or do i have to re-flash my phone??

    • Neal Pradeep

      July 13, 2011 at 9:42 am

      if you follow the procedure then it will be safe, but if you skip any instruction then you will brick the device!

        July 13, 2011 at 11:18 am

        worked perfectly!

    I installed the lag fix, ODIN says GREEN (PASSED), phone rebooted, did the data wipe, cache, but quadrant did not improve at all. Is my kernel supposed to have a different name than the one on 2.3.4 gingerbread? After I installed the lag fix, kernel did not get changed.

    hi Neal,

    I am running I9000DXJV9. According to the old post, this lagfix will only works on XXJVP version. Do you have any suggestion what should I do to install lagfix on it? To change my Kernel to XXJVP?

    If so, how could I do that? Or do you know any other sources for me to get lagfix for JV9?

    Sorry I am a noob with my SGS and it’s performance has just disappointed so much.

    • Neal Pradeep

      July 10, 2011 at 11:47 pm

      try using the XXJVQ fw as it doesn’t require lagfix!

    hi there,

    just a few questions.
    after i did all according to the instructions, i come to the recovery mode
    when i tried to wipe data/factory reset i waited for quite some time but nothing happens after that.
    in the end i just took out the battery n on the phone back
    i can still manage to on my phone without fail but is the lag fix done?
    fyi, when i open the recovery mode it is actually different from your screen shot above. mine is in red fonts n vodoo lag fix word is in place? any help?

    • Imran Ithisham

      July 10, 2011 at 1:19 pm

      Voodoo lagfix changes the recovery mode screen, the selection key is the “power key” unlike the default “middle button” The middle button turns the screen off and on upon press… Clear the cache partition and reboot your phone…

      FYI – the lagfix should be installed successfully if you can see the red recovery screen…

      • Neal Pradeep

        July 11, 2011 at 10:21 am

        voodoo doesn’t change the rebooting screen and there is nothing like that the lagfix should be installed successfully if you can see the red recovery screen…

    Hi Neal,

    I would like to ask if this lagfix can be used for 2.3.3 with kernel ver. JV6 (this is the arabic version)?

    Hope this will be OK.

    • Neal Pradeep

      July 8, 2011 at 3:23 pm

      no, the lagfix mentioned here only applies to the XXJVP version!

  33. Sambamurthy

    July 7, 2011 at 3:52 pm

    Thank you so much, I did lag fixing.But how come still I have my 2GB ( system storage) left out without using for lagfix file extension ???

  34. Amin Hussain

    July 5, 2011 at 9:31 pm

    can i just ask though, is it necessary to run the lag fix many times in the future. I have noticed that after a while , my quadrant score jumps back down to 900 from the 1900s. Can you explain why this happens?

    • Neal Pradeep

      July 7, 2011 at 10:35 pm

      no amin, lagfix just optimizes the file syste and makes it faster. its not a compulsion though!

    It seems that project-voodoo.org is not being updated anymore.. Where did you get the lagfix from??

    I’m running JVQ – will the JVP lagfix work or will it brick my device??

    Thanks!

    – Please only comments from ppl who know what they are talking about

    • Neal Pradeep

      July 5, 2011 at 4:27 am

      no it will not work for any other fw apart from the mentioned version!

      • Sambamurthy

        July 7, 2011 at 3:54 pm

        I tried it for JVQ but it just messed up.. so I intalled XXJVP and then lagfix.

    Hi Neal. Thanks a lot for your tutorial. I have flashed voodoo few days ago, everything is fine, my galaxy s is working like a charm. But I have a question, it may could be little bit irrelevant here but its the problem in samsung galaxy s with every firmware till date (or I don’t have any clue?), problem is that while making video call using yahoo messenger its rear camera turns on, front camera doesn’t. I haven’t tried video call using 3g yet. Is the application faulty or something wrong with galaxy s?? I hope you reply
    thank you..

    I have gingerbread 2.3.4 installed. After doing that upgrade, I had to restore all my installed appllications and the even the phone book. Will this be the case here as well. Do I need to re-install all my application after installing Voodoo lagfix.

    Can i proceed with the installation of Vodoo lag fix directly or do i need to reflash unrooted version of 2.3.4 gingerbread again.

    June 23, 2011 at 5:46 am

    Hi everyone.

    I strongly recommend this upgrade and voodoo lagfix.

    Not only it makes your phone work faster but also BATTERY LIFE has increased significantly.

    I have been using this for last two days. Before my battery would not last more then 10 hour with noraml phone use + bit of gaming + wifi on.

    Now it last for 10 hours with 50% battery. No I can play games and browse web and keep animated wall paper on without having to worry about battery.

    Thanks Neal. You guys are too good. Thanks heaps for this update and easy to install procedure. 😀

    I installed voodoo lagfix on my 2.3.4 Android. Everithing went fine until the wipe data/factory reset.
    In recovery mode the options are in red, not blue like it was before installing the lagfix. More than that i cant select any option. I can navigte up and dawn with volume +/- keys but when i press home button to select the option the screen turns off. It’s like i would press the power button. Press home button again and screen come sback. But the option is still not selected.
    Pls pls help.
    PS: Do i need to wipe data and clear cache for lagfix to work?…or after instalation it’s already running and wipe data / clear cahce it’s an optinal step?
    Please reply!

    Hi Neal,
    after applying Voodoo LagFix (all ok) when i restart in recovery mode first of all the options there are in red, not in blue like in your screenshot.
    I gues the lagfix is installed now because i have an option there “voodoo lag fix” or somthing like that.
    The problem is that when i press on whipe data/factory reset the screen go blank and nothing is happening. I need to restart the phone after that.
    Am I missing something?

      Actualy…any of the options there is not working. It’s like the home button instead of selecting an item si turning the screen off. If i press home button again the screen comes back…but i cand select the desired item. Not even reboot now. Any sugestion please.

        just follow the instructions again to update the same again!

    • Neal Pradeep

      June 21, 2011 at 4:47 pm

      if your phone is working perfectly fine then dont do any modifications, while if your phone is not getting switched ON then just reflash the XXJVP 2.3.4 firmware to solve the problems!

      • pyrophreak

        June 22, 2011 at 11:17 am

        Actually the same thing happened to me… but I figured out that the button to select an option isn’t the ‘Home Button’ anymore, its the ‘Power Button’!

        Worked for me.

    Got it sorted. You guys are just awesome…!!!
    On stock 2.3.3 Quadrant reading was 977.
    After upgrading to 2.3.4 + voodoo lagfix, reading is 1735.

    Thanks Guys. You guys are too good. You make it much more fun to play around with Galaxy S.

    Hi there. I have upgraded to 2.3.4 JVP.
    Now when I download voodoo hacks, it gives me two files. One is that odl thing and another one is a zImage. I can’t use zImage right? What should I do?

    Hi Neal

    My Galaxy S is with the 2.3.3 and it still seems to have a lag, can I install this lagfix on it?

    • Neal Pradeep

      June 20, 2011 at 6:35 pm

      NO Nunes, you will have to first install XXJVP fw!

    I haven’t got a 2.3.4 for my device yet. Can I install this lagfix in 2.3.3?

    • Neal Pradeep

      June 21, 2011 at 5:25 pm

      yes you can install the lag fix in your phone!

  64. Imran Ithisham

    June 20, 2011 at 5:46 am

    a must need installation for the phone because I lost the lag which I experienced after upgrading from 2.3.3 XXJVO to 2.3.4 XXJVP… you can feel the difference in performance when you open the gallery and scroll down through heavy web sites… the lag when scrolling down the contacts is gone for good and it is as smooth as silk… the quadrant score goes easily beyond the 2000 mark to prove the performance and I would highly recommend this installation to all users who are not worried about warranty… the phone gets rooted automatically and installs the super user app which works only on rooted phones… if you know how to get back to your previous firmware then this wouldn’t be a problem to try… the Galaxy S II will have to wait for sometime before she meets me because my Galaxy S is being so good to me lol!!!

      Imran, is everything ok with this voodoo fix, is there anyproblem u encounter after the installation, how about the camera and android market?

      pls reply. coz i am going to try it also.

    Hey Neal,

    First of all thanks for the last update 2.3.3 XXJVK . I was planning to upgrade it to 2.3.4 and the use the Voodoo lag fix for the same released . I want to know if there are any risks involved and what are the differences from the 2.3.3

  66. Imran Ithisham

    June 20, 2011 at 5:18 am

    The device seems to be super-fast and when I scroll down my contacts it is as smooth as silk… I felt there was more lag in my 2.3.4 XXJVP version when compared to 2.3.3 XXJVO but now it is gone for good… I would advice people to install the voodoo lag fix because after my installation the quadrant scores goes pass the 2000 mark easily and you can feel the difference when you open your gallery or scroll down heavy websites… The phone is automatically rooted and installs the super user app and this process will void your warranty, that is if you don’t know how to roll back to your previous version… Check this site about going back to your previous version, Neal has posted it already… Galaxy S II will have to wait before she meets me because my Galaxy S is being so good to me 😉

    *2767*3855# — do not try this code on your phone, it does a factory reset and wipe without prompting the user… I just did and I am bloody pissed @ the moment…

  67. Imran Ithisham

    June 20, 2011 at 4:52 am

    The phone seems to be dual core or should I say quad core after the installation lol… the quadrant scores have increased passed the 2000 mark easily and scrolling down my contacts is as smooth as silk… The phone is automatically rooted and comes with the super user app installed… Those people who are worried about warranty, please don’t proceed if you do not know how to roll back to your previous version because you would void it… In recovery mode, the power key becomes your selection key and not the home key, the home key would only switch your screen off… Thanks Neal, great job…

    OMG, that’s a BIG difference:
    – On stock Froyo 2.2.1 my quadrant score was around 1100
    – The upgraded to Gingerbread 2.3.4 – score was 1175
    – Now with Voodoo Lag Fix my score is 2003 !!!

    • donskie

      June 20, 2011 at 5:53 pm

      what do you mean by not working??? Did you have 2.3.4 version when you installed vodoo?

      • Roderick Viado

        June 20, 2011 at 11:46 pm

        Yes, its currently on version 2.3.4 baseband version I9000XXJVP, i followed all the instructions carefully and until now its not working, it only shows the samsung logo after opening and nothing is happening after that, total darkness on the screen. This is the first time i failed to update my galaxy s

        • donskie

          June 21, 2011 at 10:12 am

          can you get into download mode??? i think you need to re install the 2.3.4 and install the lag fix again. Please try to check carefully if you have kies running it should closed/ or the process should be stopped before doing anything.. hope this help. just let me know if you have still problem with your phone.

          • Neal Pradeep

            June 21, 2011 at 4:51 pm

          June 21, 2011 at 3:36 pm

          I kept on repeating the procedure but there is this robotic lady voice message that kept on repeating this phrases, “convert data partition, not enough space on partition, estimated time 2 minutes”. And still nothing happened

        • donskie

          June 21, 2011 at 7:06 pm

          just wait for a few minutes then the phone will restart.. it would take around3 to 5 minutes

          June 22, 2011 at 9:09 pm

      hi i followed all the steps and everything was going to plan. i followed all the steps. but it seems like there is no difference. im still getting scores of just 1300, i know this is ok but it seems most ppl get over 2000.

      when i try to run the odin thing again and follow all the steps again it just says removed after it reaches the “zImage” part and my phone reboots.

      what should i do ? can anyone help?

      • NeaL Pradeep

        September 27, 2011 at 7:03 pm

        unzip the files for just once and not twice!

        • Andrew

          September 29, 2011 at 5:36 am

          what?
          and i only unzipped the files once not twice.
          are you referring to the file u use for the PDA section?
          when i add the PDA file it is still a zip
          i’ve followed every step correctly
          and the same thing keeps happening
          any ideas?

          • NeaL Pradeep

            September 29, 2011 at 9:24 am

            It will be the tar file!
