    How to flash X518USQSHEZI3

    • X518USQSHEZI3 has bootloader binary H (17). Your device must run binary H (17) 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.

    Yes. X518USQSHEZI3 is the newest build for SM-X518U on SamFirm. The previous build was X518UVLSGEZI3.

    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 Tab S9 FE 5G must be on bootloader binary H (17) or lower.

    This build uses bootloader binary H (17). It can be flashed on a Samsung Galaxy Tab S9 FE 5G running binary H (17) or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". No other build of this model uses binary H (17).
