LIBTOOL

LIBTOOL (Willy LibTool) is a dual-layer Android reverse-engineering and asset-patching toolkit for Mobile Legends: Bang Bang. Operating via Shizuku and ADB without root access, it unlocks 165 Hz frame rates, custom camera views, and 40+ hero skins while providing a native C++17 IL2CPP inspection overlay.

Technical Overview

LIBTOOL executes privileged binder shell operations through ShizukuShell.java and UnityBundlePatcher.java to unpack LZMA (0x41) and LZ4 (0x42/0x43) UnityFS v7 bundles directly inside /sdcard/Android/data/com.mobile.legends/files/dragon2017/assets/ and files/mini_patch/. The Java patcher remaps m_Container path aliases inside CAB-* serialized files (AssetBundle PathID = 1) and rewrites 4-byte little-endian SkinID entries in GameResAlternative.unity3d without root permissions. On the native layer, libTool.so attaches an OpenGL ES 3 Dear ImGui overlay with runtime IL2CPP metadata reflection and inline instruction hooking via Dobby, Frida Gum, and AsmJit.

Core Features of LIBTOOL

• UnityFS Patcher: Unpacks .unity3d archives on-device to inject 40+ Collector, Legend, and Collab hero skins into mulonggame_table_1 (CAB-728f8b2bd4a2ebfb6b6f1ef7e4be6373) with zero fallback sphere errors and automatic mini_patch/ synchronization.
• 165Hz Spoofer: Injects an ASUS ROG Phone 8 Pro (ASUS_AI2401_A / Adreno 750) System Performance Table, locks peak_refresh_rate and min_refresh_rate to 165.0 Hz via Shizuku system settings, and writes HighFpsModeSee = 4 into com.mobile.legends.v2.playerprefs.xml.
• Drone Camera: Adjusts battlefield camera height across 2X to 5X presets or a 1.0x–6.0x custom FOV slider by patching SceneCameraConfig, CameraHeight, and PVP map bundles (Cab-PvpMap011_add through PVP_039_add).
• IL2CPP Engine: Integrates a stealth OverlayService HUD featuring a live IL2CPP method invoker, ?? wildcard AOB signature scanner, multi-type memory searcher (Dword, Float, Qword, Hex), and MemoryGuard anti-tamper protection.

Compatibility & Quick Setup

Requires Android 11 or newer for Wireless Debugging (or ADB on SDK 34) — install app-debug.apk, start the moe.shizuku.privileged.api service, and tap Grant Shizuku Permission.
