    Frequently Asked Questions

    M315FXXU2BUG2 is Android 11 firmware for Samsung Galaxy M31, released for 5 countries, 7 CSC codes. Samsung built it on 2021-08-03.

    No. A newer build for SM-M315F is available: M315FXXU4CXJ6. Install it instead of M315FXXU2BUG2 unless you need this exact version. The previous build was M315FXXU2BUF5.

    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 M31 must be on bootloader binary 2 or lower.

    This build uses bootloader binary 2. It can be flashed on a Samsung Galaxy M31 running binary 2 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 26 other builds of this model use the same binary, so you can switch between them in both directions.
