COPG

Overview

Developed by AlirezaParsi, COPG (Custom OEM Profile Generator) is a modern Zygisk-based per-app hardware profile spoofer equipped with a full on-device WebUI.

In the mobile gaming ecosystem, popular competitive titles (such as PUBG Mobile, Call of Duty: Warzone, Genshin Impact, and Brawl Stars) restrict graphical settings, particle density, and 90Hz/120Hz refresh rate options based on a device’s reported OEM model and GPU renderer strings. COPG lets you assign custom flagship hardware profiles on a granular, per-application basis without affecting system stability.

Technical Architecture & How It Works

Targeted Zygisk Property & OpenGL Interception

1. Process-Level Targeting: When an application process is launched, COPG checks /data/adb/copg/profiles.json to see if a custom profile is assigned to that package.
2. Build Prop Emulation: Hooks __system_property_get within the target process, returning spoofed strings for ro.product.model, ro.product.brand, and ro.product.manufacturer.
3. OpenGL / Vulkan Query Hooking: Hooks glGetString(GL_RENDERER) and glGetString(GL_VENDOR), tricking the 3D rendering engine into believing a top-tier GPU (like Snapdragon 8 Gen 3 Adreno 750) is active.
4. Isolated Scope: Apps not configured in COPG experience zero interference and read standard system properties directly from the OS.

Installation & Setup

1. Open Magisk, KernelSU, or APatch.
2. Download and flash the latest COPG-vX.zip.
3. Reboot your device.
4. Open the COPG WebUI directly from your root manager’s module interface (or browse to http://127.0.0.1:8080 if configured).
5. Search for your game in the app list, choose a target preset (e.g. ASUS ROG Phone 8 Pro), and tap Apply.
6. Launch the game, open graphics settings, and enable high-framerate modes.
