    How to flash F7310ZCS9GZE8

    • F7310ZCS9GZE8 has bootloader binary 9. Your device must run binary 9 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.
