  • Enable the USB Debugging from the path “Settings > Applications > Development > USB debugging” and also you will have to ensure that the minimum battery life should be 30% so as to ensure that the phone doesn’t get turned Off in the middle of update. Disable / uninstall all the security suites installed in your phone.

(Optional, but Recommended)

  • Now, turn Off your device so that it can be entered in the Recovery Mode. Recovery Mode in Galaxy S II I9100 can be entered by pressing the Volume Up + Menu Button and then holding these both buttons, you will need to turn ON the device so that it can be entered in the Recovery Mode.
  • In recovery mode, you need to select the option of “Wipe Data / Factory Reset” option to make sure that the data gets wiped off from your phone.

Procedure to Update Galaxy S2 GT I9100 with Jellybean 4.1.2 XWLSJ Firmware:

  • Open Odin in your computer and turn Off your Galaxy S2 so that it can be entered in the Download Mode.  Download Mode in Galaxy S2 can be entered by pressing the Volume Up rocker key + Menu Button and holding these both, press the power button at the same time while the device is turned Off.
  • Once you see the green Robot, you need to connect your phone to the computer with original USB cable by ensuring that Odin is opened in your computer.
  • As soon you connect your Galaxy S2 to the computer, you will see that the ID : COM section will turn Yellow indicating that all the drivers have been installed successfully.

Note: If ID : COM section doesn’t turn Yellow, you need to check with two things which are mentioned below,

  • Install the USB Drivers in your computer &
  • Go to the Path “Settings > Wireless & Network > USB Settings” and ensure that “Samsung KIES” option is ticked before connecting the phone to the computer.
  • Click on “PDA” in Odin to select the .tar file which you will get after extracting the XWLSJ Firmware Package in the initial step. Once selecting, click on “Start” to start the process of firmware update. As soon as the firmware is applied successfully, you will see that the device will be rebooted.
  • It will take around 4 -5 minutes for total process of firmware update and may take more time than expected for rebooting the device as it will have to finalize the installation. As soon as the firmware is updated successfully and device shows up the home screen, disconnect the device.
  • To check the firmware version, head over to the path “Settings > About Phone” where the firmware version will be mentioned as XWLSJ Jellybean 4.1.2.

Note: Just in a rare case if the device is not updated and it gets into the boot loop mode, you need to again clear the cache from the recovery mode and retry the whole process from the start.

  35. Reply Nitin Shah March 19, 2013 at 5:29 pm

    I would suggest that the publisher give out full information on various updates, especially on specific advantages and disadvantages from changing one firmware to another.For example,like reduction in battery drain and overheating isues. Lot of us have so much information and application on the phone and everytime, we change the firmware, everything has to be reloaded. For small advantage, it is not worth it.

    I would also suggest all users in India to download and install Indian specific firmware, otherwise, you will not be able to connect with KIES, neither you will be able to take advantage of Indian specific news etc.

    The file tar that got downloaded is named .tar.md5
    would be obliged if someone can let me know if we need to rename this file by removing the ‘.md5′ or just go ahead with the same file.

    one clarification required, the tar file is with an extention “.md5″
    (I9100XWLSJ_I9100XXLS8_I9100OXXLS7_HOME.tar.md5)
    Do i need to rename it and remove the “.md5″?

I am from Romania and on samfirmware.com there isn’t an oficial jb version yet. If you would install this firmware, would it be 100% functional and the same with the future update that I will get via KIES? (who knows when… :( )

  52. Reply Emad Ernest March 18, 2013 at 9:06 am

    1- Download mode by volume down + Home + Power, to confirm inside the displayed warning screen use volume up. If I am new to this and follow your text word by word it might lead to nothing.
    2- I will not update from 4.1.2 WXLSD to this one until I see from other comments that this is 100% related to S2 GT-I9100 and not to some locked phones or other versions because this is a common mistake from this site
    Anyhow, good effort.
