By Pradeep Neela / September 19, 2012 / Galaxy S II 1

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. The best part is that it also comes with the best modems which doesn’t come with issues like device getting heated up etc. This update ropes in the latest ICS Android 4.0.4 firmware version.

So before we proceed with the detailed guide on how you can install this firmware update, make sure that you follow the below mentioned pre requisites and then we will check out the tutorial in the next page. As of now this XWLPX firmware version is only available in select countries and also applying this update doesn’t root the device in any manner which means that warranty is intact even though this firmware is applied.

Data in your Galaxy S2 might get corrupted or erased. So, ensure that with the help of below mentioned steps, you are backing up all the data present so that, the data can be easily restored. Don’t backup the data using the KIES.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log -Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

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 50% 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.

  1. hey…can i revert back to gingerbread 2.3.6….if i not siuted to dis ics firmware.md is der root for this???

  2. 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.

  3. Hi Pradeep, you have replied above that there is root available , if yes then can you provide the link please, I follow your site regularly but until you have not replied in spite of me asking the same questions multiple time.

  10. Hi,
    I have a Sansung S2 with an “ancient” 4.0.4 version (I9100XWLPM_I9100OXELP8_I9100XXLQ6) and a rom to have root permission (CF-Root-SGS2_XW_OXI_LPF-v5.5-CWM5) but I have a problem with my Camera app and Video Player. Could I load XWLPX Firmware on my S2 without problems ?
    Thank you very much.
    Regards,
    Giuliano

  11. I’ve read there are serious problems with rooting LQ5/6.It seems when wipe/cache is done in CWM the phone may be permantly bricked,something to do with `Emmc bug`?

  13. The battery is brilliant on this official ROM,But the weirdest thing is happening,my battery level has gone up when I don’t use the phone from 20% to 24% which is really weird.One thing I must also add is please stop the very annoying android guide pop up,which is very annoying after a few times of continua sly closing it down

  14. What can i do if i brick my phone?
    Can i update this firmware on
    PDA : I9100XWLP7
    PHONE : I9100XXLPS
    CSC I9100XXLPH

  15. I am having S2 with the ICS 4.0.3 and the firmware version is XWLP7 when I connect it with the ODIN it doesnot turn yellow instead it is blue… Please suggest me a solution, I have done the other two methods as suggested by you but it din’t work … Help me with a solution….

  16. 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.

  17. Haven’t installed it yet because I’m very eagerly waiting for rooting instruction for this update.
    Great work guys. :)

  21. hi pradeep…..

    selected the pda file as u said…
    but still it FAILS.
    HELP ME please.

  22. 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.

  23. 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

  24. 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

  25. 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

  26. 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!!

  27. 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

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

  29. I did the upgrade, in the first look seems as it works well.
    But, once again in the screen I get a big black frame mentioning
    HW: REV
    PDA : I9100XWLPX
    Phone : I9100XXlQ6
    etc, etc until
    UniqueNumber : N
    Who can help to put out this not nice screen?
    Thanks from Portuga

      1. I agree, works perfectly but isn’t nice. Will look for something else, not official because I don’t like the frame. Do you want make an recommendation?
        Rgds from Portugal

      2. Hi sorry to come back, I guess that is perfect but, by visual reasons I don’t like have the message in the home screen. There are the possibility to delete it?

    1. I’m having the same issue. Did you get rid of it ? Please reply so i can remove it. Thanks in advance.

  30. I guess the first paragraph of the procedure that says “turn off the computer so that it can be then entered in the download mode.” should have meant “turn off the phone….”

  31. Hi,

    Can this be applied to a phone that it’s stock with GingerBread 2.3.5?build number : gingerbread.xwki8?

    Thanks in advance.
