    Hey totallydubbedhd πŸ™‚

    I have a small problem………..I downloaded my firmware from
    Its JV9(India). M not sure how to flash it. I saw your video…….but i dont understand a couple of things…….when do we select a pit file? when do we repartition?
    The ROM has the following files-
    I am going to be flashing using Odin……….a little help would be appreciated.

        you can’t flash it individually! 0.0
        Flash the file, as you said in PDA only, but put a 512 repartition and tick repartition – then you should be on stock again πŸ™‚

    1. TotallydubbedHD Post author

      you should not OPEN the zip file – I don’t know what you have downloaded is it a 4 file or 2 file one?

      PIT should be used to clear the system – i recommend putting a 512 pit and ticking repartition and flashing the rom in PDA (IF ONLY it is a 2 file one)

  4. Sid

    But where do I get the PIT file? The firmware I downloaded(.zip) had only a .tar file whose components I mentioned earlier…………….

  5. Sid

    What exactly is a PIT file? If i used the one that comes with Darky 10.2 RE would that work? It is-

      1. Sid

        Ok so the zip file I downloaded has a file ‘JV9_JV9_JV5.tar’ and ‘SS_DL.dll’……… I am assuming its a 2-file……..and m gonna flash it(as PDA) with a 512 PIT file. Is that right?

        And btw, this would wipe my internal SD too right?

        1. Sid

          Also in Darky 10.2 RE or 10.2.2, will I have to change my CSC code from KOR to INU? Does it have INU? My phone is not SIM locked

    Hi TotallydubbedHD,

    I’m from The Netherlands and I did flash 2.3.5 (XXJVS) via Samfirmware by using Odin a couple of months ago.

    Now I want to go to use an official ROM via Samsung Kies.
    To do that, I did follow your steps, flashed JPU and after that JPY (unticked re-partition).
    Samsung Kies still says that mij phone doesn’t support software updates via Kies.

    What do I have to do to have my original 2.3.3 back from Kies?

    Help me please.

    Info: Galaxy S I9000 GT
    CNC: KOR

      you should change your CSC πŸ™‚
      Hopefully once that’s done, it should do it – if all else fails, you can flash JVO 2.3.3 straight away. (which I THINK is the latest update)

      1. Sef


        I have another Galaxy S with the original JVO. When i go to settings>about phone. I got the same kernelversion, buildnumber and baseband version as my flashed JVO.

        So, why I should change CSC? I mean, how would that help?


  7. Sef


    Today Kies recognized my flashed JVO πŸ™‚ πŸ™‚ πŸ™‚
    It’s oke now.

    But I have 1 question: how can I know that my phone is now really really original (legal)?

    1. TotallydubbedHD Post author

      well – as you are on official firmware.
      If you want to sell it or warranty replace it:

      -Clear your INT SD card
      -Make sure superuser is not installed = best way would be to factory reset it.

    Hi Dear, i got Samsung galaxy s2 and it has stopped working (imei missing) so no service and strange thing is it has drained battery at all. i got a new battery but that is also dead in few hours. it is not rooted .i was told by a workshop that i need to go back install firmware (stock) again ,,,kindly help me how can i get that and do that.

    1. TotallydubbedHD Post author

      Hi there,
      Battery drain has to do with usage and the rom you’re on.
      I don’t know the s2 well enough to suggest you a particular rom.

      I suggest you don’t touch it and try to monitor what is draining your battery.
