Root XXJVQ Android 2.3.4 firmware for Galaxy S i9000 [Installation Guide]

We just posted an Installation guide for the newly leaked Android 2.3.4 firmware (XXJVQ) for Galaxy S i9000. And if you want to root the firmware, then below is the guide for you.

Warnings and Info first (even if you hate it reading again and again and…):

[info]This guide is applicable only for Samsung’s Galaxy S international version (i9000). If yours is Vibrant/Captivate/Fascinate/Epic 4G or any other Galaxy S variant, then this ROM — and Guide — is not for you, and that’s for definite.[/info]

Warning: Warranty may be void of your device if you follow the procedures given on this page. You only are responsible for your device. We wont be liable if any damage occurs to your device and/or its components.




Install instructions: Download the zip file given above and extract it to get the .tar file (a kernel), which you need to flash with Odin with ‘Re-Partition’ box unchecked and both ‘Auto Reboot’ and F. Reset Time boxes checked.

Step by Step Guide (easy edit from earlier post, lol!):

Here’s what you need to do to Root your XXJVQ Android 2.3.4 Firmware for Galaxy S:

  1. Download CF-Root kernel given above. File name – Size 6.71 MB.
  2. Unzip the above file. You will get the .tar file – CF-Root-XX_UNK_JVQ-v3.7-CWM3RFS.tar. We will be flashing this .tar file using ODIN to gain root access and install the CWM alongside.
  3. Download Odin (if you don’t have it already). File name – Odin3 v1.7. Download Link. Extract the zip file to get Odin3 1.7.exe. Run Odin by double clicking on it. (Do NOT create and open Odin using a shortcut on windows, it might result in process FAIL! in step 11).
  4. Switch Off your phone. Wait for vibration to confirm complete switch off.
  5. Boot your phone in Download Mode — Press and hold VolumeDOWN+HOME+POWER keys together.
  6. Connect your phone to PC now. You’ll notice “Added! !” message in the message box.
  7. On Odin, click the PDA tab and select the .tar file you got in step 2 — CF-Root-XX_UNK_JVQ-v3.7-CWM3RFS.tar
  8. Make sure “Re-Partition” button is NOT checked. Leave the “Auto Reboot” and “F. Reset Time” buttons checked.
  9. Double check step 7 and step 8. Your Odin’s screen should look like this:XXJVP Root Screen Before Process Starts
  10. Click the Start button on Odin to begin installing the CF Root kernel.
  11. After the CF Root is installed, phone will restart automatically. When the Galaxy S logo shows up on phone, you can disconnect it from PC. Your Odin’s screen would look like this upon successful flashing:XXJVP Root Process Finsihed Screen
  12. Your phone is rooted now. Note that surperuser app is there.

NOTE: I think the guide above is already more than enough but if some of you want to see the procedure in video, check out this video where I flashed the CF-Root kernel for XWJVB. [But you do not use/flash that file on XXJVQ. Use the file given above ONLY.]

To boot into ClockworkMod Recovery — power Off your phone completely and then, press and hold (till Galaxy S logo appears): VolumeUP+HOME+POWER. You’ll enter the CWM recovery. You can use this to:

  • Backup your ROMs
  • Restore backed up ROMs
  • Delete Backups
  • Flash files
  • Flash custom themes

From the CWM app (you get it after you’ve flashed the CF-Root), you can even flash kernels on your phone without even touching Odin.

    Hi. Great installation guide. i’m just concerned about one thing. I’ve been reading on other forums that this rooting process somehow causes bluetooth and 3g problems. Is this true and can someone correct me if i’m wrong. I just want conformation from someone that it works and is bug free.

    Again great guide

      Read the instructions carefully…. you need to extract the downloaded .zip
      file to get the .tar file which you would put in PDA tab in Odin.

    Worked great. Thanks. I was hesitant as my firmware version is 2.3.3 and baseband XXJVQ. I did take out SIM and SD card but no settings were changed or data lost on the phone. The only thing I was slightly confused about was weather I needed to put put ODIN onto phone as well as desktop. I did both just incase.
    All I need to do now is research which appps are not critical to the system.
    Thanks Chainfire.

    Worked great for me too, same fw and baseband as Haggis, 2.3.3 XXJVQ (last Kies upgrade for italian TIM-branded FW). Thanks!
    Funziona alla grande per 2.3.3 XXJVQ TIM (ultima release dell’aggiornamento tramite Kies). Grazie.

    Um – help?
    I followed your path carefully. Had the correct code name, the works.The reset started okay, but froze at the display of ‘SetupConnection’. After half an hour, I reset the handy……and that’s it. Turning it on now shows twp icons, a telefone and a computer, connected by dotted lines with a triangulaed ‘!’ in it.Anybody know what I could do? Except send it back (although I seriously need this thing)?Greetings from Munich, Germany,Klaus  Breuer

      Don’t worry. Your phone would be okay… just install the xxjvs or xxjvu firmware on it, any one of them will do good.

      Search this site for any or both them to get download links and installation guide.
