    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 A05 must be on bootloader binary K (20) or lower.

    This build uses bootloader binary K (20). It can be flashed on a Samsung Galaxy A05 running binary K (20) or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". No other build of this model uses binary K (20).
