    Frequently Asked Questions

    F731USQS6FYJ3 is Android 16 firmware for Samsung Galaxy Z Flip5, released for CHA, United States (ATT, CCT, TMB, TMK, USC, VZW, XAA). It includes the 2025-10-01 security patch. Samsung built it on 2025-10-29.

    No. A newer build for SM-F731U is available: F731USQU8HZIJ. Install it instead of F731USQS6FYJ3 unless you need this exact version. The previous build was F731USQU6FYI8.

    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 Z Flip5 must be on bootloader binary 6 or lower.

    This build uses bootloader binary 6. It can be flashed on a Samsung Galaxy Z Flip5 running binary 6 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 12 other builds of this model use the same binary, so you can switch between them in both directions.
