    How to flash S936BXXUDDZJB

    • S936BXXUDDZJB 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

    SMR Oct-2026 fixes 62 vulnerabilities, 9 of them critical. Android Security Bulletin: 45, Samsung Semiconductor: 4, Samsung-specific issues (SVE): 13.

    Yes. S936BXXUDDZJB is the newest build for SM-S936B on SamFirm. The previous build was S936BXXSDDZJ1.

    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 S25+ must be on bootloader binary D (13) or lower.

    This build uses bootloader binary D (13). It can be flashed on a Samsung Galaxy S25+ 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.
