    How to flash S918BXXS3CXD2

    Frequently Asked Questions

    S918BXXS3CXD2 is Android 14 firmware for Samsung Galaxy S23 Ultra, released for 62 countries, 109 CSC codes. It includes the 2024-04-01 security patch. Samsung built it on 2024-04-11.

    No. A newer build for SM-S918B is available: S918BXXUAGZIF. Install it instead of S918BXXS3CXD2 unless you need this exact version. The previous build was S918BXXU3CXCF.

    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 S23 Ultra must be on bootloader binary 3 or lower.

    This build uses bootloader binary 3. It can be flashed on a Samsung Galaxy S23 Ultra running binary 3 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 24 other builds of this model use the same binary, so you can switch between them in both directions.
