    How to flash S936NKSS5BYI9

    • 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.

Odin checks the built-in checksum of every .tar.md5 file before flashing. The download is 16.446 GiB; keep about twice that free on the computer to unzip it.
