    How to flash A305GUBS8CUI1

    • A305GUBS8CUI1 has bootloader binary 8. Your device must run binary 8 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.

    No. A newer build for SM-A305G is available: A305GUBS8CWI1. Install it instead of A305GUBS8CUI1 unless you need this exact version. The previous build was A305GUBU8CUG1.

    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 A30 must be on bootloader binary 8 or lower.

    This build uses bootloader binary 8. It can be flashed on a Samsung Galaxy A30 running binary 8 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 16 other builds of this model use the same binary, so you can switch between them in both directions.
