Frequently Asked Questions

A135NKSSDEYJ2 is Android 14 firmware for Samsung Galaxy A13, released for South Korea (KOO, KTC, LUC, SKC). Samsung built it on 2025-11-27.

No. A newer build for SM-A135N is available: A135NKSSEEZB2. Install it instead of A135NKSSDEYJ2 unless you need this exact version. The previous build was A135NKSSCEYG1.

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 A13 must be on bootloader binary D (13) or lower.

This build uses bootloader binary D (13). It can be flashed on a Samsung Galaxy A13 running binary D (13) 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.
