How to update Galaxy S2 GT I9100 with Official XWKL1 Gingerbread 2.3.6 Firmware

Samsung Galaxy S2 LogoGood news for Galaxy S2 users as an all new Official firmware has arrived and is dubbed as Gingerbread 2.3.6 firmware. This update will be very short lived as an all new Official version of Android 4.0 ICS will be rolling out very soon in 2012. Though this update is official you can update with the help of KIES too but for all those who are on the beta firmwares and KIES doesn’t recognize the device too can apply this update as we will see in the due course of the article on how to manually apply tis update. The update which we will be checking out is specially for Indian Galaxy S2 GT I9100 users, though it can be applied by any S2 I9100 users as it’s a Global update with Multi CSC. The version is dubbed as XWKL1 Gingerbread 2.3.6.

Note: This update is not for Galaxy S2 I9100G users and is strictly for the devices of whose the model number is GT I9100. If you are not sure of the Model number then you can find by dialing “*#1234#” in your phone after which you will get to see the model number of yours.

Disclaimer: Please note that this process of firmware update is not recommended for the basic users and is only recommended for the advanced users. Also, we should not be held responsible for any damage happened to your device in any manner after applying this update.

So, let’s proceed with the list of pre Requisites you need to follow after which we will see the procedure in the next page.

Pre Requisistes:

  • So as to ensure that the data is kept safe, you need to backup the same using the below mentioned tips so that just in case if the data gets erased or gets corrupted, the same can be easily restored with the help of below mentioned tips.

Note: Don’t backup the below mentioned data with the help of KIES as it may or may not support KIES after the update.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Notes – Manually save the notes in your mail as these will be lost in the process of firmware update
Call Log - Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • A minimum of 50% battery charge needs to be there left in the device so as to ensure that the phone doesn’t get turned Off in the middle of firmware update. The APN Settings are located in this path, Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names, you need to note all these manually on a piece of paper so that you can reconfigure the same. Disable tools like Security SuitesFirewall tools and also the KIES PC Suite as these tools generally tend to interrupt the process of firmware update.

So, once you are done with all the above instructions, it’s time to proceed to the next page where we will see on what are the instructions to update Galaxy S2 with Gingerbread 2.3.6 XWKL1.

    Pradeep i have android 4.0.3 on my I9100 but i want to downgrade is there any risk….please reply asap

    Hi,
    I’m from India and have been watching all of your articles about GS2 and i updated my GS2 to 4.0.3 as and when it was released and later i reverted back to 2.3.6 xwlk1 through Odin following your guidance lines. My phone is working fine, but sometimes when the phone is in idle mode (i.e. screen off) suddenly it turns on and turns off. There won’t be any sms or miss call when i check. Is this a virus problem or any malfunctioning? I’ve got Antivirus installed in my phone too and that didn’t find any virus either.

    One more question, when i connected to Kies it is detecting/recognizing but when i hit Firmware upgrade and initialization showing “GT I9100 does not support initializing.” Is this a problem when Samsung releases official ICS to update my phone through Kies?

    Please suggest.

    Hello, I have followed your instructions to the letter with this firmware 2.3.6 but the phone and Odin is stuck at SetupConnection.. for the last half hour. is this normal?

    How can I restart the process, because I cannot remove the USB cable. I want to wipe the phone completely and restore to 2.3.6. from 4.0.3. I had serious problems with 4.0.3. and the phone will not even boot

    Hi Np,
    I had been following your procedure and after first step. I am not getting yellow box as mentioned below…. What to do??
    “Once phone is connected, the ID : COM section will turn yellow. Click on “PDA” to select the file “Kernel_I9100XWKL1.tar.md5” and then click on “Start”. Within a minute the device will be restarted. Now after you see the home screen, remove the USB cable to enjoy your Galaxy S2 GTI9100 on the latest and official Gingerbread 2.3.6 update.”

    Thanks NP,
    Awesome guidelines and indepth “How to” help me get my S2 on new android version 2.3.6. I read this article & the comments atleast 10 times to avoid the confusion/problems & inspite of following all the steps I got one problem which was:
    Added!!
    Odin v.3 engine (ID:14)..
    File analysis..
    Enter CS for MD5..
    Leave CS..
    Can’t open the serial(COM) port.
    All threads completed. (succeed 0 / failed 1)

    As I mentioned … I read all the comments and then made my PC equipped with latest version of Kies and USB drivers. But still this problem was reoccurring. Then I did the thing which is not mentioned in the article. I cleaned my S2 … cache, history, running apps. & then atlast …. yuppie …. it worked. Now my S2 shows its Android 2.3.6 and also get detected on Kies.
    Thanks NP once again for all kind of untiring support.

    All,

    I’m also facing same kind of issue “Your device does not support software upgrading via Kies”

    Let me explain what happened exactly:

    1. After 100% charged we get an notification on top stating that 100% Charged , when I unplug the charger after that battery percentage will go down to 95% or 96% immediately as on when unplug the charger
    2. And my S2 was little bit hanging while operating
    3. While charging mobile is getting heat
    Because of all the above reasons I have approached Samsung Servicing Center (authorized) and I was to told that there is problem with Mother Board and needs to be replaced and need to update the OS also,
    After 3 days I got my mobile back with replaced new mother board and software updated, after that also above mentioned (Point 1) issue not resolved and moreover I could see and new issue that, when I tried to connect my mobile to KIES it says that “Your device does not support software upgrading via Kies” and it’s showing only current firmware version and not showing that this is the latest firmware version,
    Not sure what to do, today again I have approached Samsung Servicing Center to take look into that,
    Could someone had same kind of issue, please advice me on this.

    Hi pradeep,
    I was using 2.3.6 xxkl1, as it was not recognised by kies i followed ur guide. but i think i’m in serious problem, After the first PDA update my GS2 keeps on restarting. Its like its stuck in a vicious cycle- the animated “S” comes in then the SAmasung Galaxy SII below it again the animated “S” logo… This continues. I tried the kernel update after this and the problem is same. I never reach my home screen. My earlier 2.3.6 CSC was KOR.

    Dear Pradeep,
    The firmware is working awsome…Thank you guys…
    My phone is getting connected to KIES seamlessly and it is showing that it is official…
    And for all those people who faced battery drop issus initially…Even i suffered 50% drop in battery charge over the night time…
    Following is the solution which worked for me and now my battery survives for complete 2 days with moderate usage…
    Complete one battery recharge cycle.
    Enable When Screen turn off option in Wifi Sleep Policy
    Wifi and Network – Wifi setting – Advanced Option – Wifi Sleep Poliyc – select When screen turn off

    Deselect Turn off Wifi option in Custom Power Saving Setting.

    Hope this help you all…
    also switch off Market Data, Data Sync, GPS, Wifi, Location when not required…It gives tremendous boost to the battery.

    Enjoyyyyyyyyyyyyyyyyyy

Just to share my experience, my first upgrade from 2.3.4 to 2.3.6 did not work as expected, the firmware got corrupted and a visit to the service center helped me come back on track, the guys there put me on to a 2.3.3 and gave me some gyaan on the do’s and dont’s of upgrading. I went ahead now with the steps as mentioned here and lo.. behold… 2.3.6 is installed…. Thanks once again.

    hiThank you Pradeep Neala very much.
    I followed your 2.3.6 Upgrade instructions to the dot and the upgrade went without a hitch.

    My GS2 is much nippier now and I find it connects to my Belkin and D-Link WiFi router much better, with increased range. I am also able to get full 4Mbps on my BSNL broadband connection, although I am not sure it is related to the OS upgrade. Earlier I could not get more than 1.5-3Mbps try as much as I did at various times of the day.

    Do you have a comprehensive list of enhancements which 2.3.6 does over 2.3.4? Please reference if u do.

    We nor eagerly await your upgrade on ICS for GS2 (Presently, 4.0.3 seems buggy, from the comments on your blog).

    I will still follow your instructions, as Kies is much too unreliable. I wonder why Samsung messed up so badly on Kies.

    Do you have any heads-up on the release date when official ICS will be released for GS2.?

    Thanks once again

    Hi I updated my SGS2 to 2.3.6. The process was smooth and flawless. But after the update i am facing issues with WIFI connectivity. Once connected it works fine, but as soon as it goes in idle mode or the screen is locked if i stop using my phone, with WiFi switched ON the trouble begins. When I unlock the screen and again try to browse using WiFi the net doesn’t work. I need to restart the WiFi again so as to browse again. This issue happens again and again.

    There was no problem prior to the update. Any solution to this problem?

    For the Android Lovers, who are having problems getting their phone recognized by Kies, Please follow the instructions provided By Neal every step by step and you should not have any problem with Kies from there on. I have already mentioned in the earlier posts about the improvements in this Update. Kindly read the instructions carefully and follow the same to update or else your result will be that its not recognized by Kies, you might brick your phone or worst case scenario…..you might end up with a very expensive paper weight. Instructions are very clear and precise by Neal.

        Hello Pradeep,

        I tried upgrading through KIES to FW KL1 but it remains stuck on the page which shows…”Preparing Upgrade Components”. Any ideas on how to update.
        Will updating through odin manually to KL1 void my warranty?

        • Pradeep Neela January 5, 2012 at 2:55 pm

          no it wont void the warranty, infact its an official update!
