Magisk

Downloads | Documentation | XDA Thread

Introduction

Magisk is a suite of open source tools for customizing Android, supporting devices higher than Android 4.2 (API 17). It covers the fundamental parts for Android customization: root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt removals etc.

Furthermore, Magisk provides a Systemless Interface to alter the system (or vendor) arbitrarily while the actual partitions stay completely intact. With its systemless nature along with several other hacks, Magisk can hide modifications from nearly any system integrity verifications used in banking apps, corporation monitoring apps, game cheat detections, and most importantly Google's SafetyNet API.

Bug Reports

Make sure to install the latest Canary Build before reporting any bugs! DO NOT report bugs that are already fixed upstream. Follow the instructions in the Canary Channel XDA Thread, and report a bug either by opening an issue on GitHub or directly in the thread.

Building Environment Requirements

  • Python 3: run build.py script
  • Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
  • Latest Android SDK: set ANDROID_HOME environment variable to the path to Android SDK
  • Android NDK: Install NDK along with SDK ($ANDROID_HOME/ndk-bundle), or optionally specify a custom path ANDROID_NDK_HOME
  • (Windows Only) Python package Colorama: Install with pip install colorama, used for ANSI color codes

Building Notes and Instructions

  • Clone sources with submodules: git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git
  • Building is supported on macOS, Linux, and Windows. Official releases are built and tested with FrankeNDK; point ANDROID_NDK_HOME to FrankeNDK if you want to use it for compiling.
  • Set configurations in config.prop. A sample file config.prop.sample is provided as an example.
  • Run build.py with argument -h to see the built-in help message. The -h option also works for each supported actions, e.g. ./build.py binary -h
  • By default, build.py build binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (via the -r, --release flag), you need a Java Keystore file release-key.jks (only JKS format is supported) to sign APKs and zips. For more information, check out Google's Official Documentation.

Translations

Default string resources for Magisk Manager and its stub APK are located here:

  • app/src/main/res/values/strings.xml
  • stub/src/main/res/values/strings.xml

Translate each and place them in the respective locations ([module]/src/main/res/values-[lang]/strings.xml).

Signature Verification

Official release zips and APKs are signed with my personal private key. You can verify the key certificate to make sure the binaries you downloaded are not manipulated in anyway.

# Use the keytool command from JDK to print certificates
keytool -printcert -jarfile <APK or Magisk zip>

# The output should contain the following signature
