    Frequently Asked Questions

    I9300IUBUBNJ1 is Android 4.4.4 (KitKat) firmware for Samsung Galaxy S3 Neo, released for Trinidad & Tobago (TTT). Samsung built it on 2014-10-10.

    No. A newer build for GT-I9300I is available: I9300IDDUBQE2. Install it instead of I9300IUBUBNJ1 unless you need this exact version. The previous build was I9300IXWUBNJ1.

    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 S3 Neo must be on bootloader binary U (30) or lower.

    This build uses bootloader binary U (30). It can be flashed on a Samsung Galaxy S3 Neo running binary U (30) or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 47 other builds of this model use the same binary, so you can switch between them in both directions.
