How to flash back to STOCK Samsung Firmware (SGS)

39 Replies

Here is a full guide on how to flash back to stock!
In this video I cover:
-JPU – Full ODIN flash
-JPY – PDA Only flash via ODIN – to make it able to connect to Kies
-JVO (latest as of 17/06/11) gingerbread ROM via Kies

Remember to wipe the INT SD and Factory reset before you send it in!

Download stock firmware from here

The select Samsung I9000.

You have to register and once you download the files you will be prompted to enter a password. It is mentioned on http://www.samfirmware.com/ however here are the 2 variations of passwords you will need to extract the file to your PC:
## Password is = samfirmware.com
# Password is = samsung-firmwares.com

Enjoy!

    I followed the instructions in the video but Kies now says “Your Device Does Not Support Software Upgrading via Kies”

    Any ideas?

    Hey totallydubbedhd 🙂

    I have a small problem………..I downloaded my firmware from sammobile.com
    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-
    cache.rfs
    factoryfs.rfs
    boot(.bit)
    param.lfs
    modem(.bit)
    Sbl(.bit)
    zImage(file)
    I am going to be flashing using Odin……….a little help would be appreciated.
    thanx man 🙂

      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)

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

    What exactly is a PIT file? If i used the one that comes with Darky 10.2 RE would that work? It is-
    s1_odin_20100512.pit

        Ok so the zip file I downloaded has a file ‘JV9_JV9_JV5.tar’ and ‘SS_DL.dll’………..so 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?

          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

    Sef.

      you should change your CSC 🙂
      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)

        Hi,

        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?

        Thanks.

    Hey,

    Today Kies recognized my flashed JVO 🙂 🙂 🙂
    It’s oke now.

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

      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 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.
