By Pradeep Neela / September 8, 2012 / Galaxy S II 0

Jellybean LogoSamsung Galaxy S2 GT I9100 smartphone can now be upgraded with the latest ICS 4.0.4 firmware which was released recently in the Nordic countries. This update fixes issues related to the camera app and issues with the flash light. As of now there is no estimated time on by when there will be an official update of ICS 4.0.4 but we can expect an all new version of firmware dubbed as Jellybean 4.1.1. Please note that for applying this update, you need not root your device and also just in case if you have rooted the device, the root access will be revoked and the warranty can be reclaimed. This firmware is dubbed as XWLPO and ropes in the latest ICS 4.0.4 firmware update. This firmware has been officially released in UK and since there is no boot loader in this update, anyone can apply this firmware in their unlocked Galaxy S2 GT I9100 smartphone.

Disclaimer: If all the instructions are followed which are mentioned in this article, there is no possibility of bricking the phone. We should not be held responsible in any manner for damage happened to your Galaxy S2 due to not following the instructions.

Since this update is not officially yet rolled out in all the countries and has no boot loader, this can be applied to all the devices which has the model number of I9100. You can find the model number from the path “Settings > About Phone”. Just in case if you wish to root the device, we will very soon be coming up with the rooting article which will help you to root the device.

Before proceeding you need to ensure that all the user level data in the device is backed up since the data in the device will have to be wiped off. Don’t make use of PC Suite for backing up the data as it doesn’t support the beta or unreleased firmwares.

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

Ensure that minimum charge left in the device is 50% or else the device may get turned Off in the middle of firmware update. Disable all the security suites present in your device as these tools tend to interrupt the process of firmware update.

So assuming that you are done with all the above mentioned things, you can now head to the next page where we have summed up the detailed guide on how to apply this XWLPO ICS Android 4.0.4 firmware update.

  20. Hi Pradeep,
    It was not mentioned in the article “where” we should put the tar file we downloaded. I assumed its on the PDA ‘coz one of your reply to Jaideep C is that to “just follow the instructions, leave everything as blank other than PDA”. Anyway, thanks for the updates. Does everything work in this update? Any issues? When will the root be coming out? Thanks again and more power.

  21. Thanks for this update. Kindly check this OS with gameloft games.
    My SII gets heated up when i play HD games and automatically shut down my phone.
    Please assist me on this.

    Thank you.

      1. Thank you Neel, Works fine now. However, this could have been stated upfront in the instructions, as you have done on earlier occasions. When it official JellyBean comming for the Galaxy S3?
        Thanks once again.
        Your blogs are very useful :-)

  26. In the ODIN the ‘Boot loader’ is seen highlighted. Shall I tick this and ‘start’, and leave  PIT, PDA, Phone and CSC leave unticked???
    Please advise
    Dr. K. A. Rasheed

  27. odin turns blue NOT yellow

    what about the files …where do they go ????PDA or PHONE  in Odin ??????

      1. Same here… Why is Neel not responding.
        Onky 1 file recieved of 636MB
        Why is only 1 file reced. Where are other files?

        Pls help. Many of us are stuck

    1. It turns blue, and in the video also it turns blue and not yellow. And again it starts with this blue, not waiting for it to turn yellow and passes. But how. Please try downloading the video and see repeatedly ??????

        1. The procedure is there as a small video even now visible above o0n this page. I downloaded it in high quality and viewed it several times. In spite of the blue colour instead of the yellow on Odin, I decided to move forward, because the video gave me some confidence. I got everything successfully installed. Later when WiFi was connected some prompt came from somewhere for updating, while I was re installing all my applications from my backups. I got some updating of about 60 MB. But it made little difference. It was still 4.0.4. I am sure that 4.0.4 is much superior to 4.0.3.
          Just now I connected my phone with Kies. It prompted for yet another update. This is again 4.0.4. But the version now I got is ‘XXLQ6,.
          Great many thanks Mr.Pradeep. Please keep it up. I will definitely follow your posts in future without fail.
