    No. A newer build for SM-F731U1 is available: F731U1UEU8HZIJ. Install it instead of F731U1UES6EYF3 unless you need this exact version. The previous build was F731U1UES6EYE3.

    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.
