How to Update Galaxy S2 GT I9100 with Official ICS XWLPX 4.0.4 Firmware
Samsung 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.

But, once again in the screen I get a big black frame mentioning
HW: REV
PDA : I9100XWLPX
Phone : I9100XXlQ6
etc, etc until
UniqueNumber : N

Hello is this version better than the XWLPO?
What are the changes?
i get a’ ”’ I9100XWLPX_I9100XXLQ6_I9100NEELP5_HOME.tar.md5””’ which is about 650 mb …… can i continue with it
Can it be applied to Omega 15 ICS running rooted phone too?
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.

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!!
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
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
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
God bless you all!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I’m having trouble downloading the firmware package? It stops after 2%-3%. Any recommendations?
Still waiting for the root!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Waiting for it since long time.

Haven’t installed it yet because I’m very eagerly waiting for rooting instruction for this update.
Great work guys.
I upgraded but there is no “Airplane mode” ???? please help me is that normal ??
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.

Does this method ROOT my phone……….???????

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.
