    How to flash A300MUBS1BQB2

    • 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.

    No. A newer build for SM-A300M is available: A300MUBS1BRK5. Install it instead of A300MUBS1BQB2 unless you need this exact version. The previous build was A300MUBS1BQB1.

    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 A3 must be on bootloader binary 1 or lower.

    This build uses bootloader binary 1. It can be flashed on a Samsung Galaxy A3 running binary 1 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 45 other builds of this model use the same binary, so you can switch between them in both directions.
