Galaxy S i9000 (the S1) has got one more Android 2.3.4 build leaked to flaunt the other phones of its age, like HTC Desire, X10, Incredible, etc which are still struggling to leave the Froyo world behind and get some Gingerbread taste. Samsung’s the leader right now whether you’re talking about the software or hardware (FYI, Sammy managed to sold as much as 14 million units of S1).

The latest outta the Samsung workshops is the XXJVR Android 2.3.4 firmware that got leaked only a day or two before. It’s got a working root solution too now; so it’s time we hit upon the install instructions and root method.

But read the all Important info first:

only 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 won�t be liable if any damage occurs to your device and/or its components.

Pre-Installation thoughts:

  1. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
  2. If you have Samsung’s PC software Kies installed, un-install it first because it may interrupt the flashing process.
  3. Drivers! — it’s important you’ve the proper drivers installed. Download links below:

Installation: If Odin sounds fun to you, just go ahead and download the XXJVR Firmware (password: samfirmware.com) and install it using Odin3 1.82 included in the archive. You can use earlier version of Odin too, like v1.7, that is okay. In Odin, Select the *CODE* file in PDA tab, *Modem* file in Phone tab and *CSC* file in CSC tab. Also, select the .pit file in the PIT tab and tick the Re-partition checkbox. Or, if you don’t intend to use the .pit file, don’t select it and be SURE to leave the Re-Partition checkbox un-ticked. Hit Start!

If you didn’t get what was said above, don’t worry one bit, a detailed guide for you is just below.

Step-By-Step Guide (for not so experienced users)

Although the guide below is very much sufficient but if you want to see a video of how a Samsung firmware is flashed using Odin, check this video showing installation of an earlier firmware XWJVB on Galaxy S. The procedure is same, so it would be helpful for those who are new.

  1. Download XXJVR firmware first. Filename: I9000XXJVR.rar. Size: 229.6 MB. Download Link. (password: samfirmware.com)
  2. Extract the downloaded file ‘I9000XXJVR.rar’ to get these 5 files:
    1. CODE_I9000XXJVR_CL425308_REV03_user_low_ship.tar.md5
    2. CSC.tar
    3. MODEM_I9000XXJVR_REV_00_CL1044379.tar.md5
    4. s1_odin_20100512.pit
    5. Plus, a folder with Odin PC Software file – I9003_Odin3 v1.82.exe.
  3. Disconnect your phone if it’s connected to PC.  Then Switch it Off. Wait 5-6 seconds for vibration to confirm complete switch off.
  4. Now, put the Galaxy S in Download Mode — press and hold these keys together: Volume_DOWN+Home+Power. This is required to install the XXJVR using Odin PC Software.
  5. Open Odin (from step 2.5) — I9003_Odin3 v1.82.exe.
  6. Connect your phone to PC now. You should get the message “Added! !” under the Odin’s message box in the bottom left. If you don’t get “Added! !” message, than probably there is a problem with drivers. Make sure you’ve drivers installed (links given above).
  7. Select these files in Odin at respective tabs (check out the screenshot given at the top for help):
    1. Click the PDA Tab, and select CODE_I9000XXJVR_CL425308_REV03_user_low_ship.tar.md5 (from step 2.1)
    2. Click the Phone Tab, and select MODEM_I9000XXJVR_REV_00_CL1044379.tar.md5 (from step 2.3)
    3. Click the CSC Tab, and select CSC.tar (from step 2.2)
    4. Click the PIT Tab, and select s1_odin_20100512.pit (from step 2.4)
  8. Make sure these 3 checkboxes are ticked: Re-Partition, Auto Reboot and F. Reset Time. [Note: Since we’re using the .pit file this time, Re-Partition needs to be ticked too. If at any time you do not use the .pit file, don’t tick the Re-Partition checkbox that time. Just keep this in mind, always.]
  9. Double check everything said in step 7 and 8 above.
  10. Now, hit the START button to begin the flashing process. When it finishes, your phone will automatically reboot, upon which you can unplug the cable. Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of the Odin. If it’s in red and with FAIL written over it, the process flashing process wasn’t successful.
  11. When it restarts, your Galaxy S will be running the Android OS, v2.3.4 with Samsung’s custom UI TouchWiz 3 atop it. Check out you’re your phone’s android version here –> Settings → About Phone.
  12. (Optional, of course) If you found this guide useful, share it with your friends. That would be helping us grow too!
