How to Root the Samsung Galaxy S GT-I9000 Running Android 2.3.6 XXJVU Firmware

Thanks to our friends at the XDA-Developers forum, we’ve caught wind of  a leak of Samsung Mobile’s latest firmware–Android 2.3.6 XXJVU Value Pack firmware. This firmware packs some changes, such as the Galaxy Note Lockscreen, Face Unlock, and the Galaxy S2 Photo Editor–all three of which were previously absent on the Galaxy S. The phone’s camera also has better performance, being able to take a shot while shooting video together with a minor user-interface change. Auto-rotation is now faster, easily switching from portrait to landscape.
If you can’t stand the excitement, you can install Android 2.3.6 XXJVU firmware by using this guide.  It follows the same flashing process as for any unofficial firmware update, that is, via the Download Mode on your device and Odin3.
Because the XXJVU Value Pack is a leak of an official update from Samsung Mobile, it’s presumed that it will revoke the root access on your Samsung Galaxy GT-I9000.
But, have no fear–we can root the Samsung Galaxy S GT-I9000 after the Android 2.3.6 XXJVU firmware has been flashed. We’ll be using Chainfire’s CF-Root, a rooted kernel for “rooting beginners” and for those who want to stick as closely to the stick as possible. Developed by Chainfire, a recognized developer at the XDA-Developers forum, CF-Root takes the kernel from an original Samsung firmware and adds roots, busybox, unprotected recovery, and ClockworkMod compatibility. The rooting process is as easy as flashing the Android 2.3.6 XXJVU firmware, and takes very little time.


Before you can start rooting your Samsung Galaxy S GT-I9000, you’ll need a few things:
  • Chainfire’s CF-Root XXJVU (Rooted Kernel) downloaded to your computer.  Get it here.
  • Odin3 installed on your computer. We presume you already have this, as this was used in applying the XXJVU firmware update.  If not, you can get it here.
  • The USB drivers for your handset should already be installed on your computer.  If not, you can install the drivers along with Samsung KIES, or get the drivers from Samsung’s support site.
  • Make sure that your device has a charge of at least 70% to prevent it shutting from down in the middle of the update process.

Step-by-step Instructions

Once you have all of the requirements, you may now proceed to rooting your Samsung Galaxy S GT-I9000 in the following manner:
  1. Extract the rooted kernel from the ZIP file you downloaded.  You will get one file after extracting: CF-Root-XX_OXA_JVU_2.3.6-v4.3-CWM3RFS.tar.
  2. Launch Odin3 on your computer.
  3. Turn off your phone.
  4. Reboot your phone into download mode by holding down the Volume Down key and the OK button simultaneously, then pressing the Power button.
  5. Once the phone is in download mode, connect your phone to your computer via the USB Cable.
  6. Odin3 should be able to detect your phone.  If so, the ID:COM field in Odin3 will turn yellow.  If not, your phone was not properly detected and you should not proceed.
  7. In the Odin3 window, click the PDA button.
  8. Select CF-Root-XX_OXA_JVU_2.3.6-v4.3-CWM3RFS.tar.
  9. Under “Options” in Odin3, make sure “Repartition” is not checked.
  10. Click the Start button in Odin3.  The program will start flashing the update file to your phone.
  11. Your phone will automatically reboot after Odin3 has finished flashing the update.
  12. Disconnect the phone from the computer only after it has completely rebooted.
Your Samsung Galaxy S GT-I9000 should now be rooted. You’re now running Android 2.3.6 XXJVU firmware with root access on your Samsung Galaxy S GT-I9000. Congratulations and enjoy.
