Samsung has officially unleashed Android 4.1.1 Jelly Bean to the international variant of the Samsung Galaxy S3 GT-I9300. The said upgrade, which is for software version XXDLIB, is primarily intended for the Poland region (which also covers Austria, Belgium, France, Germany, Hungary, Italy, Spain, and the United Kingdom), but it reportedly works for any GT-I9300. The firmware update is for unbranded, non-carrier-locked devices.
Official updates will expectedly start rolling out for the other regions and carriers in the next few days.
Not that the Galaxy S3 is performing poorly on Android 4.0 Ice Cream Sandwich — it does! — but the upgrade to Jelly Bean will make the quad-core beast become more beastly in its performance. The official Jelly Bean upgrade for the GT-I9300 brings Project Butter (read: crazy-smooth display and performance) to the phone, plus a modified Settings menu, a new and more functional Notifications bar, Google Now, and several other goodies that will make you lick your lips.
This guide shows you how to upgrade the Galaxy S3 I9300 to official Jelly Bean build XXDLIB manually.

- On your PC, fire up Odin by double-clicking the executable file that you extracted from the Odin ZIP file.
- 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.
- In Odin, click the PDA button. Browse for the *.tar.md5 file that you extracted from the update package.
- Except for loading the file for PDA, leave everything as is in Odin. Make sure the “Re-partition” option is not ticked.
- Flash the upgrade to your phone by clicking Start in Odin.
- After a few minutes, if flashing is successful, Odin will let you know by displaying “PASSED” in one of its message boxes.
- Your phone will reboot automatically. When it does, you may unplug the phone from the PC when you see the Samsung logo.
