BlueStacks Root GUI is a utility designed to easily toggle root access settings and enable read/write (R/W) permissions for your BlueStacks 5 instances (specifically targeting the BlueStacks_nxt structure and the MSI App Player's BlueStacks_msi5). It aims to simplify the process described in the original guide: Root BlueStacks with Kitsune Mask by providing a graphical interface.
- Auto-Detection: Discovers BlueStacks installation paths via the Windows Registry (
SOFTWARE\BlueStacks_nxtorSOFTWARE\BlueStacks_msi5). - Instance Listing: Reads 
bluestacks.confto find and list configured instances. - Root Toggle: Modifies 
bst.instance.<name>.enable_root_accessandbst.feature.rootinginbluestacks.conf. - Read/Write Toggle: Modifies the 
Typeattribute (NormalvsReadonly) for key disk files (fastboot.vdi,Root.vhd) within instance-specific.bstkfiles. - Process Handling: Detects running BlueStacks processes and attempts graceful termination before applying changes.
 - Status Display: Shows the current Root and R/W status for each detected instance.
 - Responsive UI: Uses background threads (
QThread) for potentially long operations (file I/O, process termination) to keep the GUI responsive. - Basic Internationalization: Includes English and Japanese translations.
 
- Operating System: Windows 10 or later (due to registry keys and file paths used).
 - BlueStacks Version: BlueStacks 5 or MSI App Player (versions using the 
BlueStacks_nxtorBlueStacks_msi5registry keys and configuration structure). Compatibility with other versions is not guaranteed. - Python (for development): Python 3.7+
 - Administrator Rights: Required to read the HKLM registry and terminate BlueStacks processes effectively. Run the application as an administrator.
 - Dependencies: Listed in 
requirements.txt. Key dependencies includePyQt5,pywin32,psutil. 
- Download the Latest Executable: Go to the Releases page on GitHub and download the latest 
.exefile. - Run as Administrator: Right-click the downloaded 
.exeand select "Run as administrator". This is necessary for registry access and process termination. - Important Pre-Run Steps:
- Clean BlueStacks Install Recommended: If you encounter issues, fully uninstall all previous BlueStacks versions using the official BlueStacks Cleaner tool.
 - Install Latest BlueStacks 5: Download and install the latest version from the official BlueStacks website.
 
 
- 
Clone the Repository:
git clone https://github.com/RobThePCGuy/BlueStacks-Root-GUI.git cd BlueStacks-Root-GUI - 
Create a Virtual Environment (Recommended):
python -m venv venv .\venv\Scripts\activate
 - 
Install Dependencies:
pip install -r requirements.txt
 - 
Run the Application:
python main.py
(Remember to run your terminal/IDE as administrator if running directly)
 - 
Build the Executable (Optional):
pip install pyinstaller pyinstaller --onefile --windowed --icon="favicon.ico" --add-data "favicon.ico;." --name BlueStacksRootGUI main.py
The executable will be in the
dist/folder. 
- Launch as Administrator: Start the GUI (
.exeorpython main.py) with administrator privileges. - Instance Detection: The GUI will attempt to find your BlueStacks installation and list the instances found in 
bluestacks.conf. Statuses (Root, R/W) will be displayed. - Select Instances: Check the box(es) next to the instance(s) you want to modify.
 - Toggle Root:
- Click "Toggle Root". This enables the necessary settings in 
bluestacks.conf. - Turn this ON only temporarily while you are installing Kitsune Mask.
 
 - Click "Toggle Root". This enables the necessary settings in 
 - Toggle R/W:
- Click "Toggle R/W". This sets the instance's disk files (
Root.vhd,fastboot.vdi) toNormal(Read/Write) mode. - This needs to be left ON for the system modifications (like Kitsune Mask) to persist after the instance restarts.
 
 - Click "Toggle R/W". This sets the instance's disk files (
 - Install Kitsune Mask:
- Ensure Root is ON and R/W is ON in the GUI for the target instance.
 - Download the latest Kitsune Mask APK.
 - Launch the modified instance using the BlueStacks Multi-Instance Manager.
 - Install the downloaded Kitsune Mask APK onto the instance (drag-and-drop usually works).
 - Open the Kitsune Mask app inside the instance.
 - Tap Install.
 - Tap Next.
 - Select the option "Direct Install to /system".
- Troubleshooting: If the "Direct Install" option is missing, fully close and reopen the Kitsune Mask app inside BlueStacks. It should then appear.
 
 - Let the installation complete and reboot when prompted (the instance will restart).
 
 - Final GUI Step:
- Crucially: Once Kitsune Mask is successfully installed to 
/system, return to the BlueStacks Root GUI. - Select the instance again.
 - Click "Toggle Root" to turn the configuration setting OFF.
 - Leave "Toggle R/W" ON.
 
 - Crucially: Once Kitsune Mask is successfully installed to 
 - Verify: Launch the instance. Open Kitsune Mask; it should show as installed and active. Root applications should now work.
 - Close: Close the BlueStacks Root GUI.
 
- "Path Not Found" / No Instances Listed:
- Ensure you ran the GUI as Administrator.
 - Verify BlueStacks 5 or MSI App Player is installed correctly and the registry keys (
HKLM\SOFTWARE\BlueStacks_nxt\UserDefinedDirandDataDirorHKLM\SOFTWARE\BlueStacks_msi5) exist. - A clean reinstall of BlueStacks using the official cleaner tool might be necessary.
 
 - Permission Errors during Toggle:
- You must run the GUI as Administrator.
 
 - R/W Toggle Doesn't Stick:
- Ensure BlueStacks processes (
HD-Player.exe,HD-Agent.exe, etc.) were fully terminated before toggling. The GUI attempts this, but manual termination via Task Manager might be needed if issues persist. - Ensure you are leaving the R/W setting ON in the GUI after installing Kitsune Mask.
 
 - Ensure BlueStacks processes (
 - "Direct Install to /system" Missing in Kitsune Mask:
- Make sure Root and R/W were both ON in the GUI before launching the instance and attempting installation.
 - Try closing and reopening the Kitsune Mask app within the BlueStacks instance.
 
 - Errors during Toggle Operations: Check the status bar in the GUI and the application logs (if run from source/console) for specific error messages.
