    How to flash A037MUBS6CWJ2

    • A037MUBS6CWJ2 has bootloader binary 6. Your device must run binary 6 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.
