    Frequently Asked Questions

    A205USQS9BUC2 is Android 10 firmware for Samsung Galaxy A20, released for CHA, DSH, United States (BST, SPR, TMB, TMK, USC, VMU, VZW, XAS). It includes the 2021-04-01 security patch. Samsung built it on 2021-03-31.

    No. A newer build for SM-A205U is available: A205USQUECWI1. Install it instead of A205USQS9BUC2 unless you need this exact version. The previous build was A205USQS8BTL2.

    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 A20 must be on bootloader binary 9 or lower.

    This build uses bootloader binary 9. It can be flashed on a Samsung Galaxy A20 running binary 9 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.
