The Samsung Galaxy S II is the successor of it’s the best smartphone Galaxy S I9000, moreover Galaxy S II is to consider to be the best competitor to Apple iPhone 4. Beside high-end specifications this mobile is powered with Google Android OS.

For all those who have Galaxy S II phone, here comes good news officially from Samsung that they are rolling out firmware update to 2.3.5 for unlocked handsets in some regions. Some users are reporting that it’s available in India and United States. The official firmware release to 2.3.5 is available on Samsung KIES 2.0. So just get your USB cable and connect it with your PC and check out whether it’s available to your or not. If you are lucky enough you would be among those first users to taste 2.3.5 update.

SGS 2 UpdateThe 2.3.5 Gingerbread update comes with improved performance of GT I9100 and the exact roll out to many countries is still unclear. This update comes with TouchWiz UI changes as claimed by Apple about the patent infringements issues. And for those who are looking to update to 2.3.5 can upgrade using the procedure mentioned at Gingerbread 2.3.5 Galaxy II update.

Did you try to connect your Galaxy S II phone with PC to check for KIES update? And for those users who won’t like to wait until there is an official update, they can update to using the unofficial release of Gingerbread 2.3.5 firmware or they can have the Exynos Extreme custom ROM.

    I just recently updated my Galaxy S II and its giving a lot of problems.

    I’m aware that there are instructions to update the firmware manually, but I’m simply trying to safely update my S2 from 2.3.4 to 2.3.5 but having the following problem. If anyone can shed any light and what I can try with Kies then I’d really appreciate it…

    My phone (unlocked Galaxy S2 i9100) was 2.3.3 and I updated it successfully to 2.3.4 last year using Kies. My partner’s phone (exact same model but locked to T-Mobile) had 2.3.3 but wouldn’t update at that time.

    I recently downloaded the latest version of Kies, plugged in my partner’s (2.3.3) phone, and immediately an update was detected. The update went without a hitch and now she’s enjoying 2.3.5.

    I shut down and restarted Kies and plugged in my (2.3.4) phone, phone detected, but Kies is reporting that I have the latest firmware!!! Application or phone, the common denominator is certainly Samsung.

    Does anyone know what the hell’s going on?

    Thanks in advance.

      Its clear that T Mobile Galaxy S II has received Android 2.3.5 official update but unofficially its not available on your phone which is unlocked one. From which country you are in?

      Since this is an official firmware, it shouldn’t happen. Revert back to the old firmware and see the problem rectifies or not.

    • Yogesh Patel

      October 8, 2011 at 6:34 pm

      For your problem, I think this guide would be helpful

      Close Samsung Kies and then connect your phone and select ‘Mass Storage’ mode
      Next Mount USB via the notification bar.
      Remove any corrupt files from the phones SD cards
      1. You can use this to locate corrupt files
      2. Once found, navigate to the directory and remove them
      3. Research until none are found.
      Unmount, disconnect and reconnect the phone
      Open Kies and select the Kies option, it should now boot connect without any issues.

    For whom who displaying this msg
    “it says this verion of the firmeware cannot be updated..”
    This is known language issue of Kies. Actually it means there is no new update available..
    Just wait for some time, when new firware will available to your country, you will see the msg to update

    Recently, I have updated my SGSII with KG3 , post which if i connect my phone with laptop and open Kies, the kies gives a message that “This version of the Device can not be updated”
    Current Firmware Version: PDA:KG3 / PHONE:KG3 / CSC:KG3 (KOR)
    now you are claiming this is an official version of KIES, if i update this release will i be able to sync with KIES?


    • Yogesh Patel

      October 5, 2011 at 3:03 pm

      You willn’t be able to update in that case.

    I have tried to connect my phone SGS2 to Kies all day and struggling to find the solutions, it doesn’t seem to connect. After plug in the USB to the phone, it seems connecting and then there’s box pop up to reconnect so I did it several times but still failed. Sometimes it also asked to connect in Samsung Kies (PC suite) mode not with USB mode. What does it mean??

    I’ve done lots of search on the net with the helps/advice how to but none of them seems to work…any idea you might know what I should do? I know you can do it with Odin from unofficial release but that’ll be the last choice I’d go for to avoid resetting everything on the phone.


    • NeaL Pradeep

      October 3, 2011 at 9:48 am

      you can update with the unofficial version that is from the Odin whose link is provided in the article!

    Hi i just hooked up my s2 to Kies and the following message appeared, “S/W version in your phone is not the official version. Firmware upgrade of unofficial S/W version is not supported. Current firmware version: PDA:KI13 / PHONE:KI13 / CSC:KI13 (XEU). Does that mean there is an update available for my phone in Saudi Arabia but becos i am using the above mentioned s/w version KIES wont allow it to update latest firmware. Any way to get around this problem?

      October 3, 2011 at 10:25 am

          October 5, 2011 at 5:51 pm

          Thanks, but I don’t want to root my phone. It’s just quite funny to get an unofficial update using KIES. I wouldn’t copmlain if I have used a third party software, but KIES is THEIR program and it downloads the updates from THEIR server. Is everyone moron at Samsung to put an unofficial rom to be available? Now I can start using ODIN if I want to update in the future..
