    How to flash A307GUBU4CUH6

    • A307GUBU4CUH6 has bootloader binary 4. Your device must run binary 4 or lower: it is the 5th character from the end of your current build number.
    • CSC: Use CSC for a clean install, to change the region (CSC code), to downgrade or to repair a device that does not boot.
    • HOME_CSC: Use HOME_CSC to update the same model and region while keeping your data. Back up anyway: a failed update can still require a reset.
    • The Download Mode key combo depends on the model: see all combos.

    Frequently Asked Questions

    A307GUBU4CUH6 is Android 11 firmware for Samsung Galaxy A30s, released for 17 countries, 53 CSC codes. It includes the 2021-09-01 security patch. Samsung built it on 2021-08-31.

    No. A newer build for SM-A307G is available: A307GUBS6CWH3. Install it instead of A307GUBU4CUH6 unless you need this exact version. The previous build was A307GUBS4CUH2.

    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 4 or lower.

    This build uses bootloader binary 4. It can be flashed on a Samsung Galaxy A30s running binary 4 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 31 other builds of this model use the same binary, so you can switch between them in both directions.
