    J810MUBU3CUC1 is Android 10 firmware for Samsung Galaxy J8, released for 14 countries, 32 CSC codes. It includes the 2021-03-01 security patch. Samsung built it on 2021-04-10.

    No. A newer build for SM-J810M is available: J810MUBU3CWB2. Install it instead of J810MUBU3CUC1 unless you need this exact version. The previous build was J810MUBU2CTJ3.

    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 J8 must be on bootloader binary 3 or lower.

    This build uses bootloader binary 3. It can be flashed on a Samsung Galaxy J8 running binary 3 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 10 other builds of this model use the same binary, so you can switch between them in both directions.
