    How to flash X135GDXS4BZB6

    • X135GDXS4BZB6 has bootloader binary 4. Your device must run binary 4 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.

Odin checks the built-in checksum of every .tar.md5 file before flashing. The Samsung Galaxy Tab A11 LTE must be on bootloader binary 4 or lower.
