Identifying the Right Version

The international GT-I9300 had several Android 4.3 builds. The most stable and widely used "final" versions include: I9300XXUGNA7 (Released in 2014) I9300XXUGMJ9 (One of the first stable 4.3 rollouts) I9300XXUGNG3 Always match the Country/Region Code

Important Note: The Samsung Galaxy S3 GT-i9300 (International Exynos version) officially stopped at Android 4.3.

Why Android 4.3 for the Galaxy S3 GT-I9300?

Before diving into the download links, let’s clarify why users still seek Android 4.3 (build JSS15J) for this specific model:

  1. Stability: Unlike custom ROMs (LineageOS, etc.), the official Samsung firmware has fully working RIL (radio), Wi-Fi Direct, Bluetooth, and Samsung’s camera drivers.
  2. Performance: Android 4.3 introduced TRIM support (fstrim), which significantly reduced the infamous “eMMC lag” on the GT-I9300.
  3. Features: This version brought Samsung’s "Premium Suite" – including Lock Screen widgets, improved Notification Panel, and better multi-window support (on some builds).

Troubleshooting: "Failed to flash" or "No official 4.3 for my region"

  • Your eMMC is too new/old: Some late-production S3 units shipped with a bootloader that rejects 4.3. Solution: Flash 4.1.2 instead.
  • Your region never got 4.3: Use the BTU (UK) firmware – it is multilingual and works on all GT-I9300s.

Prerequisites:

  1. Backup your data (This wipes everything).
  2. Samsung USB drivers installed.
  3. Odin v3.13 (or v3.09 for older PCs).
  4. Battery charged above 70%.
