A newer build for SM-S916N is available: S916NKSU8GZIF.

    How to flash S916NKSS6CYB3

    • S916NKSS6CYB3 has bootloader binary 6. Your device must run binary 6 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.

Odin checks the built-in checksum of every .tar.md5 file before flashing. The download is 9.347 GiB; keep about twice that free on the computer to unzip it.
