    How to flash A045MUBSCEYF1

    • A045MUBSCEYF1 has bootloader binary C (12). Your device must run binary C (12) 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

    A045MUBSCEYF1 is Android 14 firmware for Samsung Galaxy A04, released for 16 countries, 41 CSC codes. It includes the 2025-07-01 security patch. Samsung built it on 2025-07-24.

    SMR Jul-2025 fixes 32 vulnerabilities, 1 of them critical. Android Security Bulletin: 22, Samsung Semiconductor: 1, Samsung-specific issues (SVE): 9.

    No. A newer build for SM-A045M is available: A045MUBSHEZH2. Install it instead of A045MUBSCEYF1 unless you need this exact version. The previous build was A045MUBSBEYD3.

    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 A04 must be on bootloader binary C (12) or lower.

    This build uses bootloader binary C (12). It can be flashed on a Samsung Galaxy A04 running binary C (12) 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.
