Galaxy S2 LogoSamsung Galaxy S2 GT I9100 users can now install their phones with the latest stock firmware which is dubbed as XWLPX firmware which is the ICS firmware. Very soon in the coming days, the latest Jellybean 4.1 update will be coming up but this XWLPX version comes with add on stabilities in the Camera and also battery life has been considerably increased from all other previous builds.

    Hi,

    I would like to ask. I’ve applied this update to my phone but I have a bit of problem. There are images that I’ve taken prior to updating to ICS that are now showing as corrupted. I can see the thumbnails when opening the folders but when I tried opening the images themselves, it becomes just a box with a white icon and thunderbolt. I also can’t transfer them to other folders.

    Kindly advise. Thanks.

  30. Hi Neela, I have upgrade to several of your official update successfully. thanks. but is the following portion always necessary? the upgraded phone functions normally even If i don not do the following:

    In recovery mode, select “Wipe data/factory reset” & “Wipe Cache partition” for clearing out all the cache data present in your device. Once it’s done, select “reboot system now”.

    Let me know whether skipping the above mentioned step would harm the performance in any sense.

  47. This version is for which country? When is 4.0.4 releasing for India?

  48. Thanks for the good work.

    Please what is the difference between this update and XXLPO.

    XXLPO if fine but my gameloft games are shutting down my phone.

    What are the changes. Thank you.

  49. Still waiting for the root!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  50. I’m having trouble downloading the firmware package? It stops after 2%-3%. Any recommendations?

  51. God bless you all!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  52. I’m currently (and probably will be for a while longer) in Kenya, one of those countries that have NEVER had Samsung bother themselves preparing an update for (I’m now starting to think Nokia Lumia, even with its poorer Windows marketplace, at least with Nokia you get the updates. My 701 running the Belle FP1 can attest to that).
    But I digress. Can this be applied to GT-I9100 with Gingerbread 2.3.3 (stock) Build number GINGERBREAD.XWKF3? And does it have performance issues that I’ve read about online when people upgrade from Gingerbread to ICS? Issues like malfunctioning apps, etc.
    Your help will be very much appreciated

  53. so this is like an ota/kies update? will i continue receiving future updates normally (jellybean) Help me cause i’m new to rooting/flashing. Tks

  54. Sorry about the stupid question but my phone is rooted and has remix resurrection 3.0.6 ..van I install it on do I have to put the original room and unroot it? Thanks

  55. Ive only had my S2 for about a month and have never done any updating or rooting to previous androids that ive owned. Is it easy enough for a beginner to do something like this? I have no idea what to expect. Are there any references to more detail on this update? Thanks!!

  56. I am presently on Official XWLPO version which i have rooted. If i update to this version i have following queries.
    1) Will my root access will be revoked. I use Titanium back up pro to restore my application ans system data.
    2) If root revoked, then can i just wipe my cache and do not do a factory reset to keep the data.
    Help appreciated.
    Regards

  57. Can it be applied to Omega 15 ICS running rooted phone too?

  58. i get a’ ”’ I9100XWLPX_I9100XXLQ6_I9100NEELP5_HOME.tar.md5””’ which is about 650 mb …… can i continue with it

  59. Hello is this version better than the XWLPO?
