XXJW4 Root and ClockworkMod Recovery for Galaxy S


Samsung officially released the XXJW4 firmware, which is the Value Pack firmware Samsung promised for the Galaxy S after they announced that it won’t be getting Ice Cream Sandwich. The Value Pack brings along a few features from ICS, along with general speed and performance improvements.

Those who flashed the XXJW4 firmware can root it and install ClockworkMod (CWM) recovery (which lets you flash custom ROMs on the phone) by flashing the CF-Root kernel released by XDA recognized developer Chainfire, who’s always quick with his releases of rooted kernels every time a new Galaxy S firmware is released.

Read on for the full step by step procedure to install CF-Root kernel on your phone to root the XXJW4 firmware.


This firmware and the guide below are compatible only and only with the Samsung Galaxy S, model number GT-i9000. It’s not compatible with any other device and may render an incompatible device unusable. Check your device model in Settings » About phone.


The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

Pre-Installation Requirements

  • If you have Samsung’s PC software Kies installed, un-install/shut it down completely from the taskbar first because it may interrupt the flashing process.
  • Drivers! — it’s important you’ve the proper drivers installed. Download links below:

How to Root and Install ClockworkMod Recovery on XXJW4

  1. Make sure you’ve installed XXJW4 firmware. Try this only on XXJW4 firmware and not on any other firmware.
  2. Download CF-Root kernel from the official download page → here.
    Filename: CF-Root-XX_OXA_JW4-v4.4-CWM3RFS.zip
  3. Unzip the above file to a folder once. You will get the .tar file – CF-Root-XX_OXA_JW4-v4.4-CWM3RFS.tar — inside the extracted folder. It’s recommended to use 7-zip free software to extract it. DO NOT extract the .tar file (even if you see it as a zip file, which it is not). You need to flash the .tar file using Odin to gain root access and install ClockworkMod Recovery (CWM) alongside. If you’re getting zImage file, it means you’ve extracted the .tar file too! — and that’s not a right thing to do.
  4. Use the Odin software you used while flashing the XXJW4 firmware. In case you don’t have it anymore, download it again.
    Download Link  | Filename: Odin3 v1.7.exe
  5. Switch off your phone. Wait for vibration to confirm complete switch off.
  6. Now, put the Galaxy S in Download Mode — press and hold these keys together: Volume_DOWN + Home + Power until a screen saying Download comes up.
  7. Open Odin now. Connect your phone to PC now. You’ll notice “Added!!” message in the Odin’s message box in the bottom left.
  8. In Odin, click the PDA tab and select the .tar file you got in step 3 — CF-Root-XX_OXA_JW4-v4.4-CWM3RFS.tar.
  9. Important! Do not touch any other button or make any other changes in Odin except selecting the required file as given in step 8.
  10. Click the Start button in Odin to flash the CF-Root kernel.
  11. After CF Root is installed, the phone will restart automatically. When you see PASS written in top left box, you can disconnect the phone from the computer.
    IMPORTANT Note: If ODIN gets stuck at some stage and doesn’t seem to be doing anything, do this — disconnect the phone from the PC, close ODIN, remove battery, re-insert it, turn phone on in Download mode again, and do the procedure again from Step 7. Same if you get a FAIL message in Odin.
  12. If you face any problems while flashing CF-Root, let us know and we’ll try to help you out.

Your phone is rooted now and CWM recovery has been installed on it. Whenever you try to use an app that requires root permissions, you will get a Superuser prompt, where you can select Allow to grant root access to the app. Custom ROMs can be flashed by booting into CWM recovery when needed. And that’s it. Enjoy!

    Usually, after rooting the official firmware, my phone boot audio would be disabled. For this firmware it still plays every time I boot my phone. Any ideas how could I get rid of that annoying sound? Thanks in advance.

  2. Siddharth Chobe says:

    After performing all the steps, my phone is not booting up. It is rebooting again and again and I could see only GALAXY s GT-I9000 screen .
    Please help!!!

    • Kapil says:

      Which firmware did you try on this? You sure your firmware was xxjw4?

      • Siddharth Chobe says:

        Hi Kapil,

        I used it on gingerbread 2.3.3 which I upgraded directly through Samsung Kies software.
        Now the thing is, it has gone. Please tell me steps to do it from scratch wherein I can install rooted OS and if possible ICS. (considering my cell is not booting up looks like OS is also corrupted or lost)

        • Kapil says:

          You know, you can get ICS from here — http://www.theandroidsoul.com/galaxy-s-gets-android-4-0-based-aokp-rom/ Step 1.1 will also fix your phone and then continue with step 1.2 and onwards.

          • Siddharth Chobe says:

            thanks Kapil. the way we can install 2.3.6 directly as mentioned in step 1.1. Can’t we install ICS directly,

          • Kapil says:

            No, can’t install ICS directly.

          • Siddharth Chobe says:

            also, is Samsung Galaxy S I9000 international version is something different. how do I check tht. I bought it from India only.

          • Kapil says:

            Model number has to be i9000 (check in settings – about phone).

          • Siddharth Chobe says:

            I cannot check settings now since my phone is not functional but I believe it is same or may be : GT-I9000.

            wud there be any issue with this installation or may be upgrade later with ICS

          • Kapil says:

            Check on the box your Galaxy S came packed in with. If it’s GT-i9000, then go ahead.

          • Siddharth Chobe says:

            when I try to go to download mode, I can see screen saying “Downloading…”
            is it fine to start from there or I should be getting some other statement.

          • Kapil says:

            Yes. That’s the screen. Now, open Odin and then connect your phone to PC. You should get ‘Added !’

          • Kapil says:

            Yes. That’s the screen. Now, open Odin and then connect your phone to PC. You should get ‘Added !’

          • Siddharth Chobe says:

            thanks,I hve been able to upgrade it to 2.3.6. now will root it and then will install ICS. Lets see how it goes from here. 

          • Siddharth Chobe says:

            Hey Kapil, my phone is rooted as welll now. Pls let me know if I’ll go to ICS, whether I would that would be having a rooted ICS?

          • Kapil says:

  5. Harish says:

    Hi Kapil. I tried rooting xxjw4 and now my phone doesn’t go past the first screen. Its stuck there. Can you please help? Please email me.

  6. iAfficianado says:

    Hi! Thanks for all your hard work!

    I installed XXJW4 using the more recent JW4_JW5_JW4.tar file; all went well. Can I root with the above rooting kernel, or do I need a more recent version of it – the above seems to be ..JW4_v4.4… ?

  7. Bassem says:

    there is something wrong with this root file as soon I flash the mobile with it the I need to install busybox something go wrong the screen start to switch on and off and I can not do anything with the mobile please can you advise what I have made wrong
    thanks for your help

  8. iAfficianado says:

    Hi, Kapil! Having installed XXJW4 using the more recent JW4_JW5_JW4.tar file, as mentioned in my previous post, I tried to check out the differences between it and the earlier JW4_JW4_JW4.tar file; as far as I could discover, the differences were minor. I therefore decided to root my GT-I9000 as per your instructions. Everything went smoothly and – so far, at least! – everything seems to be working fine. Again, many thanks.

  9. Ketan says:

    Thank you !

  24. ynr says:

    I tried tried and tried. I almost gave up. I stumbled up on this page. Odin rocks! Such simple instructions. Thank you so much!!!

  25. Luka says:

    All I’m doing fine. When the phone is turned on I got CWM, Tweaks and supers. I installed Root Checker and he tells me Sorry! This device does not have proper root access. Why?

  26. Luka says:

    Repaired, I went into the supers and allowed chacker root access and now says This device has root access! Do I need to allow and Tweaks and CWM?

  27. Maurice B says:

    Worked like a charm for me. Thanks!
    Now I was able to make a full backup of my stock 2.3.6, this felt safe before doing more flashing.
    After this I installed CyanogenMod 10.0 (latest stable), and people, my i9000 really flies now!

    For me it was either trying this, or buying a new phone, because my beloved i9000 was ‘dying’ of slowness. No need to buy new one now, this is fast and lean!

  28. Graham Like says:

    Excellent. I’ve bee searching for ages to find clear instructions. Yours worked perfectly. I used Odin3_v3.07 from http://forum.xda-developers.com/showthread.php?t=1722686

  32. disqus_CcZ6d4paNN says:

    bad link for odin 1.7 please correct it else remove this page from your site

    thank u

  33. Jake says:

    Worked for me! Make sure you use Odin3 v1.7.exe and follow the steps to the letter. Also, make sure that if you connect your phone to your PC before starting the tutorial, Windows DOES NOT prompt you about drivers or try to set them up. Windows should do nothing. I’ve got a feeling a lot of these cases of the install failing are caused by windows dicking around with drivers while Odin is running.
