    How to flash S741NKSS2AZI3

    • S741NKSS2AZI3 has bootloader binary 2. Your device must run binary 2 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.

Odin checks the built-in checksum of every .tar.md5 file before flashing. The download is 13.564 GiB; keep about twice that free on the computer to unzip it. The Samsung Galaxy S26 FE must be on bootloader binary 2 or lower.

    This build uses bootloader binary 2. It can be flashed on a Samsung Galaxy S26 FE running binary 2 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 2 other builds of this model use the same binary, so you can switch between them in both directions.
