    A307GUBS3ATA1 is Android 9 (Pie) firmware for Samsung Galaxy A30s, released for 11 countries, 12 CSC codes. It includes the 2020-01-01 security patch. Samsung built it on 2020-01-07.

    No. A newer build for SM-A307G is available: A307GUBS6CWH3. Install it instead of A307GUBS3ATA1 unless you need this exact version. The previous build was A307GUBU2ASL2.

    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 A30s must be on bootloader binary 3 or lower.

    This build uses bootloader binary 3. It can be flashed on a Samsung Galaxy A30s running binary 3 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 1 other build of this model uses the same binary, so you can switch between them in both directions.
