    How to flash A546EXXSNFZI1

    • A546EXXSNFZI1 has bootloader binary N (23). Your device must run binary N (23) 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.

    Download the package for your region (CSC) and unzip it. In Odin, load each file into the slot with the same name: BL, AP, CP (if the package has one) and CSC, or HOME_CSC to keep your data. Odin checks the built-in checksum of every .tar.md5 file before flashing. The Samsung Galaxy A54 5G must be on bootloader binary N (23) or lower.

    This build uses bootloader binary N (23). It can be flashed on a Samsung Galaxy A54 5G running binary N (23) or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 1 other build of this model uses the same binary, so you can switch between them in both directions.
