    • 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.

    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 A30s must be on bootloader binary 2 or lower.

    This build uses bootloader binary 2. It can be flashed on a Samsung Galaxy A30s 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.
