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.

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

  2. 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.

  3. 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

  4. Hi,
    I updated the firmware, but when the phone restarts, it keeps on showing the starting screen with “S” logo and doesn’t proceed further. kindly help..

  5. I did what you said but it won’t start,continues to restart and seeing and seeing again the same samsung logo . please help

  6. I restarted the phone and allowed omputer to get all drivers, as i was getting USB drivers issue… now its working fine, thanks buddy!!!

    Now tell us the procedure to update for ICS…:))

  7. 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.”

  8. hello,
    After the update using odin, I connected my phone to kies and what i recieved was that the phone is not supported for kies update. Is this a problem and also does it mean that i can use kies to update my phone again.
    thanks

  9. first your ICS ruined me, and now the password for this package is bogus. Wow advices.com, dont want anything more from you. Pathetic level of diligence.

  10. hey bro my phone is stuck on s2 animation and its keep restarting but not showing home screen :( what to do ??

  11. 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.
    Balkrishna.

  12. Forgot to provide my Current firmware Version: I9100XWKL1/I9100ODDKF3/I9100DDKE4/I9100XWKL1 (INU)
    Please help me out in this.

  13. 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.

    i have the galaxy SII GT-I9100 from Germany, running version 2.3.4 and Baseband version I9100XXXKI1 and build # GINGERBREAD .XWKI4 , But now living in the United Arab Emirates, Throgh Kies it says that i have the latest update, and the phone does not support arabic language as a second language. what should i do.

  27. Does it take so long when select file “GT-I9100_INU_I9100XWKL1_I9100ODDKL1_I9100DDKL1.tar.md5” and click on “Start”?

  28. 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

  31. I did a factory reset on my Samsung Galaxy SII after it stopped detecting my SIM card but after doing that it got stuck on the boot animation. I’m getting the following message when I do a factory reset via Recovery Mode:

    Also, before entering Recovery Mode it asks for a pin code that I’ve set up when I configured my work email on the phone. This phone is not rooted (using stock ROM/firmware). Is there anything else I could do before I opt to bring to the service center?

I went ahead now with the steps as mentioned here and lo.. behold… 2.3.6 is installed…. Thanks once again.

  81. I am unable to download the firmware using the link http://downloads.androidadvices.com/S/GalaxyS2_I9100_XWKL1_INU_2.3.6.rar

    please help..

  82. 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

  83. helllo neal,ive got a serious question for which im not able to find the answer anywhere.im currently using xxki3 and its rooted,the thing is im not able to install custom roms n im not able to make a backup of my stock,it says e:signature verification failed,i even tried toggling the signature settings but still its the same reply i get from my phone.ive been trying so hard to install cyanogen 7.1 stable and im just not able to.will be very pleased if u can give me a solution and it will be great if u can post an article on installing custom roms.

    thankyou for the reply in advance

  84. 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?

  85. Is it possible that you can provide with a CSC file for this firmware so we don’t get an error on kies???

  86. Helloo..

    I have updated my galaxy s2 via odin with the instruction mentioned to update the samsung official version and it got updated. Later once i got connected to kies it gave a message \Your Device Does Not Support Software Upgrade Via Kies\.

    Please let me know what can i do and have i lost my warranty. Mine is a indian made and i don’t know what to be done…

    I hope you provide me a solution.

  87. can this process be used to downgrade my GT I9100 from 4.0.3 to 2.3.6? facing a lot of bugs in the ICS 4.0.3

  88. Dear Neela,

    As i mention earlier on, i have try many time and you have reply that it is for india user. so do i have to apply kernel only to 2.3.6 xwkk5 firmware or upgrade to 2.3.6 xwkl1 firmware and also the kernel? Currently i back roll to 2.3.6 xwkk5 firmware as my kies still able to recognise it.

    Rgds..

  89. Hi Neel,

    Successfully upgraded the phone. The phone is Indian make and is to be used in India. Followed the exact procedure as mentioned but still kies is not recognizing the phone. At the end of my current firmware listing it shows XEU in brackets. I think that is the issue…. Can you please guide me to change that and get my phone re-detected…Do I need to do anything else like factory reset or cache clearing..?

    Waiting for a quick and positive answer..

    Thanks
    Dhrupad

  93. I think this is the clearest guide ever! :D I salute the maker of this. :D

    thou i have flashed mine before i read this, but still. :D would share this to other SII users. :D Keep up!

    • thanks for your trust and appreciation!

      • how do you update kernel on odin?

        • we have mentioned the same in the article!

        • correct me if im wrong if i understand it correctly when u say update kernel it is the step where u flash the kernel on odin? (this step)

          ■ 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.

          because im done with that but still kies cant do update on my phone…

  94. Hello Pradeep:

    Thank you very much for this firmware update, Its Rocking I upgraded from 2.3.3 to 2.3.6 and lots of bugs have been fixed in my S2.

    Including my battery issue which use to drain out in 8~9 hours, after the upgrade I am able to fetch my battery to 10~12 hours. Which is remarkably good.

    However I found a issue after the upgrade, whenever I open any application, there is a slowness and able to see the pixel by pixel on the screen while opening the application.

    Earlier this was very smooth and fast without any delay in opening the application.

    Pls help if this is a know issue.

    Regards,
    Vivek

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.

    Thank You Neal and Android Team, You Guys Rock.

    I have done all my updates from this site and honestly it Rocks. Thanks Neal and the Android Advices Team for bringing the best to the Android Community.

    My first question on the Android Advisces was if there will any update to get 3g Video calling available on the Galaxy S2, well its finally answered in this update… YES, We can now make a normal 3G Video calls to any phones which support native video calling. I dont mean Skype or GTalk, just the regular Video Call. AWESOME. I really hope that this function will not be removed from the Ice Cream Sandwich Update. Thanks Neal for Bringing this Update to us. I know that many users have been missing this function.

    Additional to that, also settings for delay in lockscreen and password (alphanumeric).

    Cheers Mate.

    Thanks for any advice.

  154. After update my Kies shows ” Firmware cannot be updated through Kies” on the home screen

    Any Idea what’s going on…?

  155. Hi Folks,

    I just updated both the files and its successful, just one doubt, my Kies was working with the Beta firmware as well as this official one of 2.3.6 but it was showing “this device cannot be updated by Kies” on Beta as well as on official one. any Idea why…?

  156. Can you please tell us what happens to the apps that are not purchased through the android market assuming that those apps can be downloaded again without repayment. This is the only aspect that keeps me from updating…please guide me

  159. Anyone know what’s changed between 2.3.5 and this, other than the standard Google enhancements?

  160. Hi Neal

    i updated the PDA file and then i did not updated the kernel
    instaed i used the CWM 5 kernel provided by you for rooting

    phone is working fine

    I dont understand y u asked to flash the kernel file “Kernel_I9100XWKL1.tar.md5″ ??
    i guess its already in the main PDA file

  161. Does 2.3.6 has improved battery performance compared to stock 2.3.3?

  162. Hi Pradeep,

    I think you need to edit the article a bit as the places where is says that we need to select a PDA file doesn’t says which file we need to select and instead only ” ” are placed over there.

    So without knowing which file to select at a particular point, I suppose none would be able to install this update.

  163. I manually installed this version but is not recognized by Kies. Why?

  164. In your instructions, you ask us to click on PDA and select the file “”. Please specify which file, as there are two. Also do we have to do it two times, as said in the instructions ???

  165. How to root this firmware i upgraded via Kies to 2.3.6

  166. Dear Niel,

    Thanks for providing the latest official update, I am using the Beta update provided on your website, I am downloading the firmware now but when I go through the installation process I guess you missed the file name to be selected and it only shown as empty commas, so kindly provide the file names to update both the files in a proper order.

    Cheers,
    Pinaki

  167. Where will the other file goes? Kernel_ I9100….? where will you click it… there are two files on the zip folder… will we use only the first one? thanks.. and after this can kies recognize the phone??? Thanks mate..

    I will be waiting for you reply and by the way.. great work… appreciate it much

  168. Hi
    I had updated with “XWKK5 Gingerbread 2.3.6″ few days ago so.. is this needed.

  169. is this the latest official FW???

      • 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?

      • Dear Neela,
        Does this update (XWKL1 Gingerbread 2.3.6) support arabic

      • Thank you pradeep for this very nice article.I tried to update my sgs2 with kies 4days ago.It stopped in the middle and the phone didn’t reboot.I searched for a solution and luckily found your aricle.I got my phone using a USB JIG.I followed your instructions and got my phone back alive!!!and all the data is SAFE.
