    How to flash A037MUBU5CWF3

    • A037MUBU5CWF3 has bootloader binary 5. Your device must run binary 5 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

    A037MUBU5CWF3 is Android 13 firmware for Samsung Galaxy A03s, released for 14 countries, 43 CSC codes. It includes the 2023-06-01 security patch. Samsung built it on 2023-06-12.

    No. A newer build for SM-A037M is available: A037MUBSBCYE4. Install it instead of A037MUBU5CWF3 unless you need this exact version. The previous build was A037MUBS4CWD1.

    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 A03s must be on bootloader binary 5 or lower.

    This build uses bootloader binary 5. It can be flashed on a Samsung Galaxy A03s running binary 5 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.
