  41. 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.

  42. 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.

  51. Come on every one is having the same problem… please advice

  52. Flashed…works nice

  53. Dr. K. A. Rasheed

    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

  54. odin turns blue NOT yellow

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

    • Dr. K. A. Rasheed

       I also got only one MD5 file.
      Lost here. Do not dare to move forward

    • please follow the insturctions

    • 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 ??????

      • which video you are talking about?

        • 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.

        • How do I root now ???

        • It is just above a page length from here

  55. nice..

  56. nice..
