Rooting Information:

Also, additionally just in case if you have rooted your phone then the rooting access will be revoked as soon as you apply this update on your phone. You can root your phone again if you wanted after applying this update. We will soon be coming with the procedure on how you can root the device within few days of time, so stay tuned to

Note: In the process of updation you will be losing all the data which is SMS, Contacts, Music, Videos and Pictures if they are stored in the phone. All the contents stored in your external SD Card will stay intact and no contents will be modified in the external SD card. Additionally, all the APN Settings as well as the MMS Settings too will be erased, so you need to ensure that you are noting all this settings somewhere so that you can then restore the same by configuring it manually once the firmware updation process is done.

    I have troubles with Odin detecting my device connected to the computer.
    Is there any certain trick how the connection can be established?
    Thanks for the help.

        October 24, 2011 at 10:37 am

        Are you saying Odin should be run from the phone directly?
        I thought the instructions said to use an USB cable.

    Do i really need to clear cache and “wipe data”. Would it really make the phone much faster? The update worked perfect. I just want to know if the last step will help a lot.

      just try removing the battery and then re inserting? we think there is an issue with the unlocking process which you had done! Visit the Samsung Service centre to fix the same and then you can enter into the download mode. you can check the same once again!

          September 26, 2011 at 5:20 am

          After hours of struggle and praying… I was able to reverse it back 2.3.3


          if you are stuck with BOOT LOOP; follow this instructions
          1.) Turn off your phone, remove battery/sim/micro SD
          2.) Press & Hold the VOL UP+VOL DOWN
          3.) Plug your phone into your computer (Keep holding those buttons)
          4.) Download mode should pop up.

        Hi Pradeep,

        I just realized I did a blunder by selecting Re-partition option while running the upgrade program and I guess that could be the reason for the mess up

        • NeaL Pradeep

          September 25, 2011 at 11:42 pm

    NeaL Pradeep is notorious for releasing so called “leaked” firmwares that either brick phones or have excessive issues, any advice he gives you disregard it if you value your phone…

      • NeaL Pradeep

    Thanks a whole lot.. I was able to update to this update and was no hustle… First i freaked when my first attempt failed. I got it to download mode and Odin recognized it and it failed. I took the battery out and the phone did not boot. i had a little phone icon connecting to the computer. I closed Odin and opened it again and picked the files and it worked.. I had all my contacts and my APN was intact..very funny thanks a whole lot………………..

    This update is great even more so since you don’t have to be rooted. I was rooted before this and since updating see no reason to now since the phone is running in tip top condition. Lastly I noticed that if you are upgrading from the last gingerbread release that you don’t actually lose all, of your info/data so if you read this before updating then test assure that you will be ok. Oh yeah and you get a cool keyboard,that lets you txt in different languages lol enjoy

    • jb4g

      September 12, 2011 at 11:38 am

      Are you sure you are getting the phone into download mode? Bc if not then you will keep running into the same problem

      • NeaL Pradeep

        September 16, 2011 at 7:08 pm

    The information is clear but in my case,

    the ID:COM is not turning yellow and when I try to start the update, I receive this report… All threads completed. (succeed 0 / failed 0)

    Are my doing something wrongly.
    What must I do to update??
    Thank you so much.

    • NeaL Pradeep

      September 12, 2011 at 9:09 am

      the ID : COM will only turn yellow once you connect the phone in the download mode!

      • Prince Edem

        September 12, 2011 at 4:19 pm

        Yes, I have connected the phone in download mode but the ID:COM still wont turn yellow.

          My phone firmware version is 2.3.4. It is saying I9000XXJVP is the base band version.
          Is there a difference between this and the UVKG4?
          The model number is of course GT-I9000

    Hey Mike,
    try booting your phone into recovery mode and then wiping your cache. I was about to apply the update again and I remembered that one of the optional things we were asked to do was to wipe the cache. I did this and my phone booted normally and I breathed a huge sigh of relief.

    • Mike

      September 12, 2011 at 10:06 am

      Dude I’m scared bro this was my first time doing this but this is what my screen says:

      E: failed to mount /data (Invalid argument)

      — Applying Multi-CSC…
      Installing Multi-CSC
      Can’t access to ‘/system/csc/TMB/system/’.

      • NeaL Pradeep

        September 12, 2011 at 10:09 am

        • NeaL Pradeep

          September 16, 2011 at 6:03 pm

          pull off the battery!

        • Ricky

          September 16, 2011 at 7:32 pm

          I did pull out the battery. That did not solve anything. I found a different way to get in to download mode and luckily unbrick my phone.
