Update Galaxy S2 to Android 2.3.6 XXKL1 Firmware

XXKL1 Android 2.3.6 Installation

Firmware leaks keep on coming in the world Samsung Galaxy devices, and the latest of them is Android 2.3.6 based firmware for Samsung Galaxy S2 ─ XXKL1.

It’s the fourth leak of Android 2.3.6 based firmware, and as always I’ve no idea what’s changed (guess nobody has). Anyway we’re going to update ;)

NOTE:
This guide is applicable only for Samsung’s Galaxy S2 (S II) international version (i9100). Check your phone’s version in Settings – About Phone. It has to be “GT-i9100” for the XXKL1 firmware to be compatible with your device. If it’s not GT-i9100, simply don’t try this ROM on your android handset, don’t even think about it if you care not to brick your device.[/info]

Warning!
The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to you or your device, we won’t be held liable. You only will be responsible — you’ve been warned. Okay!

Pre-Installation tips:

  1. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
  2. If you have Samsung’s PC software Kies installed, un-install it first because it may interrupt the flashing process.
  3. Drivers! — it’s important you’ve the proper drivers installed. Download links below:

Installation video

The video given below shows the installation of an earlier firmware (XXKG1), but the steps to update to XXKL1 are all similar, so you can easily follow the video to get some visual guidance.

Step by Step Instructions:

  1. Download the Android 2.3.6 Firmware – XXKL1. Filename: I9100XXKL1_I9100OXAKL1.rar. Size: 299.5 MB → Download Link. (password: sampro.pl)
  2. Extract the downloaded file ‘I9100XXKL1_I9100OXAKL1.rar’ to get these 4 files:
    1. CODE_I9100XXKL1_CL783870_REV02_eng_mid_ship.tar.md5
    2. GT-I9100-CSC-MULTI-OXAKL1.tar.md5
    3. MODEM_I9100XXKL1_REV_02_CL1085162.tar.md5
    4. u1_02_20110310_emmc_EXT4.pit (we won’t be using it since it’s not essential for flashing the firmware. Read Step 13 below this to know more)
  3. Download Odin software. Filename: Odin3-v1.85.zip. Size: 198 KB → Download Link. Extract the zip file to folder to get 2 files – Odin3 v1.85.exe and Odin3.ini. Do not delete the .ini file (the second one) since it’s very much required, too. when asked in step 6 below, open Odin by double clicking on the Odin3 v1.85.exe file.
  4. Disconnect your phone if it’s connected to PC.  Switch Off your phone. Wait for vibration to confirm complete switch off.
  5. Now, put the Galaxy S2 in Download Mode — press and hold these keys together: Volume_DOWN+Home+Power. this is required to install the XXKG1 using Odin PC Software.
  6. Open Odin (from step 3) — Odin3 v1.85.exe.
  7. Connect your phone to PC now. You should get the message “Added! !” under the Odin’s message box in the bottom left. If you don’t get this message, than probably there is a problem with drivers. Make sure you’ve drivers installed.
  8. Important! On Odin, Do NOT tick the ‘Re-Partition’ checkbox, but keep the ‘Auto Reboot’ & ‘F. Reset Time’ checkboxes ticked. Do not touch any other checkbox or tab or anything, except as required in step 9 below.
  9. Select these files in Odin at respective tabs (check out the screenshot given at the top for help):
    1. Click the PDA Tab, and select CODE_I9100XXKL1_CL783870_REV02_eng_mid_ship.tar.md5 (from step 2.1)
    2. Click the Phone Tab, and select MODEM_I9100XXKL1_REV_02_CL1085162.tar.md5 (from step 2.3)
    3. Click the CSC Tab, and select GT-I9100-CSC-MULTI-OXAKL1.tar.md5 (from step 2.2)
  10. Double check everything said in step 8 and 9 above. [And, do not use the file in step 2.4 anywhere in Odin]. Your Odin’s window should look real similar to the image at the very top — which is my Odin’s screen while I flashed the XXKL1 on my Galaxy S.
  11. Now, hit the START button to let the process begin. When process at Odin finishes your phone will automatically reboot — and you can unplug the cable then. Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of the Odin. If it’s red and with FAIL written over it, the process flashing process wasn’t successful.
  12. When it restarts, your Galaxy S2 will be running on Android 2.3.6 with Samsung’s custom UI TouchWiz 4 atop it. Check out your S2’s android version here – Settings → About Phone.
  13. About the .pit file (one you found in step 2.4). The .pit file re-partitions the phone’s internal memory space. You don’t need it often, that’s why we don’t use it generally. But if you are unable to flash the XXKL1 ROM successfully, you can try the whole process again but using the .pit file too this time.
    Important: When you use .pit file (ever!) you need to tick the Re-Partition checkbox too (which wasn’t the case earlier – check step 8 when we kept it un-ticked). So, if you are flashing the XXKL1 again, select the .pit file too (from step 2.4 ) in the PIT Tab together with all other files as said in step 9. Then, make sure the Re-Partition button is ticked too along with the Auto Reboot and F. Reset Time checkboxes — that is, all three checkboxes will be ticked if you use the .pit file.
  14. (Optional, of course) If you found this guide useful, share it with others too on webpages, forums, your Facebook/twitter/Google+ pages, etc. That would be helping us grow too!

If before flashing this, you had your phone rooted you would want the root back, right? Well, that’s very obvious. But chainfire hasn’t released a working root for XXKL1 yet. So I’d suggest you to root using SuperOneClick, it may work.

Do let us know about your experience of the XXKL1 ROM in the comments below.

    you guys are my heros. after a failed firmware upgrade via Kies (connection timed out twice), I got hold of I9100XWLP3_I9100O2ULP4_O2U and was greatful that my phone worked. However, this put an O2 logo on startup screen and used them as carrier (not too bad considering I am with Tesco mobile). problem was that I couldn’t use mobile data and feared a long call to Tesco helpdesk. Then discovered your very helpful website which helped put my ‘Android’s Soul’ right again. THANK YOU GUYS!!!

    Hi there.. After installing I have two problems. One, the battery drain really fast. Two and the most important one, when I off my phone(after waiting for the last vibration) the phone turns off well but suddenly the battery symbol came up and starts to blink with a yellow triangle and a thermometer sign with it. How do I solve these problems?

       hey man can you tell me whether it works for Galaxy sii Baseband version I9100XXKI1 

      • http://www.theandroidsoul.com/ Kapil

        If you are looking to install ice Cream Sandwich on your Galaxy S2 with baseband XXKL1, you can do so without any worries. We would recommend you to install the latest Samsung leaked firmware — XXLPH ( http://www.theandroidsoul.com/xxlph/). It’s the best!

        • Thanushka_rc

           no man I’m not going to install ice cream sandwich. I just want to upgrade it ti 2.3.6 version(Gingerbread). My Baseband version is I9100XXKI1 not I9100XXKL1 is it ok to do this installation  

          • http://www.theandroidsoul.com/ Kapil

            Oh ok… ya no probs whatsoever with you upgrading to XXKL1 using the guide above. Go ahead. Take care to take backups as said in pre-installation tips above, of SMS, calls, and most important of them all, APN settings which you’ll need for internet.

    Well, didn’t work for me on my main PC (W7 64bit), but then Keis had just managed to wipe the firmware and refuse to perform an emergency recovery on the same computer…just deep joy! Odin could see the S2, but just threw back a red FAIL box when I pressed ‘Start’.nnTried to use Keis and the operations above on my netbook (W7 32bit) and that failed too; I couldn’t get the USB drivers to work…nnThird time lucky on my works laptop (W7 64bit). u00a0Keis refused to see the S2, but Odin picked it up and after 3 mins or so my S2 was flashed and working…nnty for the guide, very, very useful…roll on Android 4.0 for S2

    • Garf

      2 week sin and I’m finding this version of firmware heavy on the battery (even with JD paid for) and the phone not as ‘snappy’ at responding to finger presses, etc.

      Also, first time I’ve seen a kernel panic on my phone with this build.  

      • Garf

        Well I’ve just flashed my G2 to 4.0.3 XXLPQ and it is so much better.  My phone is significantly faster, uses less battery juice.  I am very impressed with 4.0.3.

    Rooted with SuperOneClick v2.3.1 successfully !!

    You must wait 5/10  minutes till the end :p

    Restart ,enjoy :)

  • Dverwoert

    Installed 
    Update Galaxy S2 to Android 2.3.6 XXKL1 Firmware
     
    Rooted with 
    SuperOneClick v2.3.1
    takes 5 to 10 minutes and gave a message that the phone was already rooted which I ignored and the program said it was not responding several times but just waited and waited until it finally finished installation and shut off. When I restarted my phone was rooted. Installed Titanium Backup and recovered all programs and data. 

    Great operation by following directions and being patient.

    Another question, is there any support for unicode languages like Hindi/Malayalam/Tamil etc with the latest firmware update? If not any idea when android would start supporting unicode?

    Thanks

  • Anonymous

    Are there any ways to get the customization back after upgrade, like all the personalization, shortcuts added etc?

    • http://www.theandroidsoul.com Shivam

      No, but if you’re rooted you can take a complete backup with “*Titanium backup*” (search for it in the Market) before upgrading to the new firmware. And restore the backup after you upgrade.
