  13. basically the same instructions can be found (just much less explicitly described).

    One difference bothers me:

    You propose to use for CSC the file:
    GT-I9100-CSC-MULTI-OXAKG2.tar.md5

    The author of the mentioned side is aware of this file, but emhasizes to use this file instead:
    GT-I9100-CSC-HOME-MULTI-OXAKG2.tar.md5

    What is the difference? What is correct?

  14. hey thanks man…updated my galaxy successfuly….

    I have all this steps very carefully….
    and pls clear why there r two csc files in this packages…

    pls reply

    1. 1. make sure you’ve installed Kies (the official samsung galaxy software) on your PC. You won’t need to un Kies but it installed the drivers required by Odin

      2. Make sure you’re running a full-fledge Windows. Odin will not detect USB devices when ran from a virtual machine (like Parallels or Fusion on a Mac)

      1. Thanks for including the driver file in the XXKG3 package! I have to reinstall this and restart the computer for this to work. Now I have the upbeat version on my S2.

  15. I managed to get XXKG2 successfully. Any idea how to revert to the original 2.3.3 version that came with the phone, just in case I need to claim for warranty ?

    1. Good day,
      Where did you get the update software? I tried to download but it gives me page not found. Where can I download?

  16. u said this is unofficial and unstable version….
    u really think one should update with this.
    Im confused. :-(

    1. hey sandeep its an un official and since its a beta update there will be some bugs! You can update with the same as other good things too are mentioned!
