    How to flash J400MUBSDCUK3

    • J400MUBSDCUK3 has bootloader binary D (13). Your device must run binary D (13) 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

    J400MUBSDCUK3 is Android 10 firmware for Samsung Galaxy J4, released for 14 countries, 34 CSC codes. It includes the 2021-11-01 security patch. Samsung built it on 2021-12-07.

    No. A newer build for SM-J400M is available: J400MUBUECWC1. Install it instead of J400MUBSDCUK3 unless you need this exact version. The previous build was J400MUBSDCUK2.

    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 J4 must be on bootloader binary D (13) or lower.

    This build uses bootloader binary D (13). It can be flashed on a Samsung Galaxy J4 running binary D (13) 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.
