    How to flash W9026ZCS2AYJ3

    • W9026ZCS2AYJ3 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.
    • 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 17.416 GiB; keep about twice that free on the computer to unzip it. The Samsung W26 must be on bootloader binary 2 or lower.

    This build uses bootloader binary 2. It can be flashed on a Samsung W26 running binary 2 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". No other build of this model uses binary 2.
