Instructions

  1. Extract the XXUGMK6 update ZIP file’s contents into a convenient location on your computer, preferably the Desktop.  The most important file is the one that ends in *.tar.md5.
  2. Extract the contents of the Odin ZIP package into a folder on your Desktop.
  3. Turn off your phone.
  4. Reboot your phone into Download Mode by holding down the Home, Volume Down, and Power buttons together.  When you see the Samsung logo, you may release the Power button, but keep the Home and Volume Down buttons pressed down until the phone boots into Download Mode.
  5. On your PC, fire up Odin by double-clicking the executable file that you extracted from the Odin ZIP file.
  6. Connect your phone to your PC via USB cable.  Odin should be able to detect the phone and display “Added” in its message box.  If you don’t see such confirmation, the software may be having trouble detecting the phone, in which case you can try reinstalling the phone’s USB drivers.
  7. In Odin, click the PDA button.  Browse for the *.tar.md5 file that you extracted from the update package.
  8. Except for loading the file for PDA, leave everything as is in Odin.  Make sure the “Re-partition” option is not ticked.
  9. Flash the upgrade to your phone by clicking Start in Odin.
  10. After a few minutes, if flashing is successful, Odin will let you know by displaying “PASSED” in one of its message boxes.
  11. Your phone will reboot automatically.  When it does, you may unplug the phone from the PC when you see the Samsung logo.
Awesome!  You have successfully upgraded your Samsung Galaxy S3 GT-I9300 to official Android 4.3 Jelly Bean build XXUGMK6.
