    No. A newer build for SM-X700 is available: X700XXSBEZH3. Install it instead of X700ZCU9EYJ4 unless you need this exact version. The previous build was X700XXS9DYI1.

    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 download is 8.356 GiB; keep about twice that free on the computer to unzip it.
