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

  2. 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.

  3. Hello sir,

    When will you provide the root information for this firmware.

    Waiting for it since long time.

  4. Still waiting for the root!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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

  6. God bless you all!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  7. 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

  8. 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

  9. 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

  10. 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!!

  11. 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.
