    Hi, is this work on non rooted telephones because I have already updated my 4.0.3 software with Odin even my phone is not rooted so will it work and with 4.0.4 ?

  • 20stz

    Hello, i’ve updated to 4.0.4, but I have some problems.
    1. It tells me I have updates on software, downloads 9MB and reboots to update firmware then it doesn’t and when phone boots it says: “Failed to update firmware. Try again using pc software (kies) or visit a samsung service centre”.
    2. I can’t use the phone camera, when I try to use it i can’t see nothing, it’s black screen, but if I hit the capture button it takes a picture of what the camera is pointed at.
    Please help me!

    Works perfect, without any bugs !!! The most interesting thing is that, I can still update my phone via OTA and can receive updates. Few days ago the phone received new update version XWLPT via OTA !!! I’m happy :)

    I’m Stuck in Samsung Galaxy s2 GT-I9100 screen even how many times i Re-install and
    Factory Reset :( please help

  • Hems

    Installed and running so far so good.

  • choppaa

    I just did this, and it worked almost perfectly! I have been to xda developers several times, but this is hands down the most straightforward guide to installing the latest firmware for my phone, and that’s why I decided to bite. I ran into the fail message with the red background, but I followed the steps and it worked the second time. It took me about 7 minutes and was so simple. My phone had a baseband UHKI2 and I could not find anything about when it would get updated, so I was stuck on 2.3.4. Now it’s at 4.0.4, and it feels great to have known that I did this, thanks to you!
