Stock ROM Samsung Galaxy: New Method 2018

By 

This guide outlines a new method for installing the stock ROM on Samsung Galaxy phones in 2018.

“With the Android Oreo update, the Samsung firmware flashing process has changed. It now consists of 5 separate files including AP, BL, CP, CSC, and HOME_CSC, all required to be installed separately via Odin.”

Older Samsung phones used single-file firmware updates, but new Galaxy phones from 2017 onwards with Android Oreo require multiple firmware files for updates, which may continue with newer Android versions.

This guide simplifies the confusing flashing process on Galaxy devices by explaining the purpose and location of each file.

This guide covers the installation process and benefits of installing a stock ROM on Samsung Galaxy phones, such as improved performance and situational benefits.
