    How to flash A305GUBU3ASK2

    • A305GUBU3ASK2 has bootloader binary 3. Your device must run binary 3 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.

    A305GUBU3ASK2 is Android 9 (Pie) firmware for Samsung Galaxy A30, released for 13 countries, 23 CSC codes. It includes the 2019-12-01 security patch. Samsung built it on 2019-11-20.

    No. A newer build for SM-A305G is available: A305GUBS8CWI1. Install it instead of A305GUBU3ASK2 unless you need this exact version. The previous build was A305GUBU3ASK1.

    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 A30 must be on bootloader binary 3 or lower.

    This build uses bootloader binary 3. It can be flashed on a Samsung Galaxy A30 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.
