Find your country below, verify the file and download for free. Compared with the previous build A336NKSS8EXH1: bootloader binary raised from 8 to 9, so after installing it there is no way back to older builds; security patch 2024-10-01 instead of 2024-08-01. A newer build for SM-A336N is available: A336NKSUGGZI2.

    • 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.
