    Frequently Asked Questions

    A155NKSS9CZB4 is Android 16 firmware for Samsung Galaxy A15, released for South Korea (KOO, KTC, LUC, SKC). Samsung built it on 2026-03-05.

    No. A newer build for SM-A155N is available: A155NKSSBDZH6. Install it instead of A155NKSS9CZB4 unless you need this exact version. The previous build was A155NKSS8CZA2.

    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 A15 must be on bootloader binary 9 or lower.

    This build uses bootloader binary 9. It can be flashed on a Samsung Galaxy A15 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.
