    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 A21s must be on bootloader binary 8 or lower.

    This build uses bootloader binary 8. It can be flashed on a Samsung Galaxy A21s running binary 8 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 4 other builds of this model use the same binary, so you can switch between them in both directions.
