  26. Why is that my comments awaits moderation? Truth hurts?

  27. Dear All
    i have updated this version and definately the speed has improved a lot. everything is working well, the scrolling also has improved
    the only thing is that the Phone heats and the battery drains very fast. Hopefully there will be some solution to thiss soon.
    Thanks a lot to Mr. Pradeep Neela for sharing and his patience.

  28. Has anybody encountered any issues with this version? Can somebody confirm if the battery drain problem is resolved!?

    Also how do I get 50GB dropbox account?

  29. My model no. Of samsung galaxy s2 is gt-i1900g

  30. Dude i m from odisha (india) my samsung galaxy s2 is running in ice cream sandwich can i update this to jelly bean, and plz also tell me when jelly bean is officially launched in india……

  31. Am still a newby at flashing ROMs so pls bear with rather basic questions.

    My GS2 already rooted and with 4.2.1 Resurrection Remix AOKP installed.
    Can I revert to this 4.1.2 XWLSJ using Odin to instal..? Or is there another method for rooted devices when I want to revert to official ROMs?

    Will I lose root after reverting to official ROM..?

    Thank you very much.

  32. Hey admin.
    I have croatian S2 and can I update my phone with this update?
    Baseband version:I9100XXLPW
    Kernel version: 3.0.15-I9100XWLPD-CL524746 dpi@Dell154 #3
    Build version: IML74K.XWLPD

  33. The odin is not detecting my phone in download mode. But the text turns yellow when the phone is switched on. :(. Even Kies is detecting my phone.. Whats the issue??

  34. 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.

  35. 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.

  36. 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″?

  37. Updated but through OTA via Kies
    I found no difference ever: over heating and Battery drain might be worse
    I hope that Samsung will come with solution OTA soon

  38. Dear Pradeep,
    1. Can we apply this in India?
    2. I had applied the earlier JellyBean version XWLS8 and is working fine. Except for
    huge battery draining its gr8.
    However
    3. when i enable the News ticker in the lock screen i do not get to select India. Is
    there any way to get Indiaan News on the locked screen ticker?

  39. hey admin. please tell me the difference between XWLSD & XWLSJ?? What’s the benefit of xwlsj over xwlsd? Currently i am on xwlsd. Is there any advantage to go on xwlsj?

  40. Hello AndroidAdvice. I have a question. Should i update my carrier-free Galaxy S2 with this last oficial firmware or should I wait for the update via KIES?? I mean really oficial style. 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… :( )

  41. HI,
    I updated but there is no change it is the same only in the settings when i checked the android version it is showing XWLSJ Jellybean 4.1.2 but I dint find any new options which are mentioned in the change log of this article. Kindly let me know why it is like that.

  42. I have receive an update over wifi and install it,now my version is XWLSJ.

  43. Hello Adroid Advice :) I’m Just Wondering, Can I Update My SGSII With This New Offcial Firmware “Again”? Because I’ve Already Flashed My SGSII With The Offcial Spain Firmware XWSLD,,, Please Can You Help Me? Thank You :)

  44. Something is different… Could you revise how can I put my mobile in Download Mode? Thanks a lot!

  45. Hello:
    Afraid I am confused and am seeking clarification….

    Wasn’t this Jellybean 4.1.2 XWLSJ Firmware already released back in Dec 2012…???
    Why is it being listed in AndroidAdvices now again?
    Or is it being listed now because it has not been listed here yet?

    Or is this an UPDATED version on the Dec 2012 firmware with the SAME reference 4.1.2 XWLSJ..??

  46. How is this different from XWLSD? What about India specific CSC?

  47. Hi ..what one is the latest? XWLSJ or XXLS8 that i’m using now..thanks

  48. Hi Android Advices Team
    Problem Odin by Hotfile there is no download it says (This file is either removed due to copyright claim or is deleted by the uploader.) Please can you fix this?

    Thanks
    Michael

  49. Dear All,
    in the instructions it is mentioned ” Download Mode in Galaxy S2 can be entered by pressing the Volume Up rocker key + power button at the same time while the device is turned Off”
    as i understand we need to press the volume down key + power button along with the power off.
    also i would like to know if others have tried this and if it is applicable for India as well.

    • its Volume Down + Menu Button and Power Combo…

    • Hi all, I have followed the methods to start the phone to download mode. It works. all you have to do is ON the phone with 3 buttons all pressed together !!

  50. “Download Mode in Galaxy S2 can be entered by pressing the Volume Up rocker key + power button at the same time while the device is turned Off”

    New way to enter Download Mode?

  51. 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.

  52. I have 4.1.2 XWLSD,can i update this firmware over existing firmware and do i have to root device?
    Thank you.

  53. Can i do this for my Tmobile version (sgh-t989)?
    & what are the known bugs?
