    Frequently Asked Questions

    I9300UBUGNI1 is Android 4.3 (Jelly) firmware for Samsung Galaxy S Ⅲ, released for Brazil (ZTO). Samsung built it on 2014-09-23.

    No. A newer build for GT-I9300 is available: I9300XXEMU8. Install it instead of I9300UBUGNI1 unless you need this exact version. The previous build was I9300XXUGNH4.

    Download the package for your region (CSC) and unzip it. In Odin, load each file into the slot with the same name: BL, AP, CP (if the package has one) and CSC, or HOME_CSC to keep your data. Odin checks the built-in checksum of every .tar.md5 file before flashing. The Samsung Galaxy S Ⅲ must be on bootloader binary U (30) or lower.

    This build uses bootloader binary U (30). It can be flashed on a Samsung Galaxy S Ⅲ running binary U (30) or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 49 other builds of this model use the same binary, so you can switch between them in both directions.
