Samsung starts Android 4.1.2 Jelly Bean update for the Galaxy S II GT-I9100G

Samsung has just started to push Android 4.1.2 Jelly Bean update to the Galaxy S II (GT-I9100G). The Galaxy S II is the best-selling Android device of 2011 and has a very large user base that’s why Samsung keeps on updating this device with all the new Android versions as they want to provide the Galaxy S II users with their best support experience.

You might not be able to update your device to Android 4.1.2 Jelly Bean right away as the update is rolling out in phases. So, it might not yet be available for your country or network provider (If Your device is Carrier branded) but don’t worry the update will arrive soon.

In the history of software updates, the new Jelly Bean update by Samsung to the Galaxy S II is by far the most major update given to a smartphone yet. As we all know Samsung’s ICS update didn’t had any UI changes and had exactly the same UI which was in its Gingerbread but this is not the case with Samsung’s Android 4.1.2 Jelly Bean update. The new jelly bean update breathes a new life into the Galaxy S II, Samsung has completely ditched the old UI and has given the new Nature UX Interface, which is the same as the one being used in the Galaxy S III Mini and the Galaxy S III, in its latest Jelly Bean update.

Some of the Enhancements in the new Jelly Bean Update:
- Buttery Smooth Performance & Great Stability (Thanks to Project Butter)
- Full User Interface Revamp (Same UI as of the Galaxy S III and Galaxy Note II)
- TouchWiz Nature UX
- Samsung’s S Cloud services
- Improved Camera features
- New Lockscreen With Many Customization Options
- New Features like Direct Call, Smart Stay and Pop-up Play
- New Widgets (From Galaxy S III)
- 2 Home screen modes
- New Notification bar With More Notification Toggles
- Google Now

You can update your Galaxy S II (GT-I9100G) through Samsung KIES or via OTA. Make sure you fully charge your device’s battery before upgrading as the update is quite big.

Official Firmware Details:
Android Version: 4.1.2 – Build JZO54K

All the new Android 4.1.2 Jelly Bean Firmwares for the Galaxy S II are present in our Firmware Section as well. You can use our Firmware Section to manually update your device if for some reason you can’t officially update your device via Samsung Kies or via OTA as you are using a Custom ROM or if your Country has yet not received the Android 4.1.2 Jelly Bean Update. Also, bookmark this page as we will keep this page up to date with the latest information on countries and network providers releasing the Android 4.1.2 Jelly Bean Update.

  22. @vaniprasadrao : Did i missed it out by few minutes?

  23. Thank you samsung…
    Excuse me for cpmplaining!
    I’m sorry.

  24. I just updated the firmware of my I9100 hoping that it was JB. However it was not and the version still shows as 4.0.4. the update was successful. Any idea as to what it was?


  25. Hey there, gotta Noob question: If I download the firmware from another country (say Spain or whatever) will I be given the option to change the language? (I’m pretty sure the one I have now was Polish and I put it to English but it is has been over a year so I can’t remember).

    Regardless of the fact that I live in France and my phone is unlocked/rooted and all that jazz (so Id prefer unbranded), even downloading/waiting for the French version wouldn’t be my solution since I’m a native English speaker (unless of course language is modifiable).

    So to anyone kind enough to answer a noob, thanks in advance!

  26. @dkchauhan please keep us update…
    thanx in advance…

  34. You’ve got to be kidding me. Now that the i9100 update whining is getting less the N7000 update whining starts….. Get a life dudes….

  35. @AnexRavesong

    if you do a completely clean install (clear cache,data etc.) you get the option to select your language on the firmwares first run.

    Don’t forget to backup your data first and make a note of your account usernames/passwords.
    I use a handy little utility called super backup from play store which backs up your call data, contacts, calendars, sms and apps.

No bugs at all and the good news for users in Kenya where I live – the sim toolkit works excellent so you can use all your money transfer functions too. I downloaded the France JB firmware. Bye bye ICS. Well done Samsung.

  102. 1 bug. Sometimes the phone will turn off if u leave it for a while. Need to replade batery to turn it on.

  103. I update my SGSII by Odin, but the battery is not work very well!!!!
    I think ICS battery performance is better.

  104. My phone has a 4.0.4 french firmware installed (PDA:LPY / phone:LPV / Csc: LPY (XXX)) but still says no update available when trying to update from settings. and kies says update not supported via kies. Is this normal? Am I not supposed to get the update available notification instead?

  105. your product code not active and with Kies not update. You can chang your product code with SRS product changer program. You can find in google this program. Ok

    wow works smoothly & not faced any bugs still now.checked most of them all working fine.
    RAM also increased to 796. great keep it up samsung. friends this one works in india……keep going

    • Hi, I just want to know something about this JB update.
      When I installed ICS, i was having two three major issues for me.

      1) Manual brightness adjustment from notification bar was not working. Can you please confirm that its working or not?

      2) My total RAM was decreased to 687MB from 1 GB and now you are saying that its increased to 796. Do you know why its not 1 GB?

      Does anyone know, how can i keep a backup of current firmware before upgrade (using Kies)? So i could move back to previous firmware?

      Thanks in advance… :)

  134. deena u got no warranty pal..?

    and i feel india got the most S II customers and y not releasing in india 1st :|

  135. marshal you are right. not bothered about it, i want to see my s2 with latest firmware……

  136. @deena143 & marshallrebel : Since this is official ROM and there is no need to ROOT, warranty is not voided. If needed official old ROM or jelly bean ROM (once released for India) can be again replaced.

    Please check using volume up+power+home — it will say samsung official and custom software as NO
