    Frequently Asked Questions

    No. A newer build for SM-A217N is available: A217NKSUBDXJ1. Install it instead of A217NKSU7CUI3 unless you need this exact version. The previous build was A217NKSU6CUG1.

    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 7 or lower.

    This build uses bootloader binary 7. It can be flashed on a Samsung Galaxy A21s running binary 7 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 1 other build of this model uses the same binary, so you can switch between them in both directions.
