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 2.65 GiB; keep about twice that free on the computer to unzip it. The Samsung Galaxy A7(2017) must be on bootloader binary 9 or lower.
