AltA2DP Driver Patcher

Overview

A simple AoB patcher for Alternative A2DP by Luculent. Modifies both AltA2dpConfig.exe and AltA2DP.sys to bypass license checks and make the program free to use beyond the trial period.

Features

• Automated Patching: Simplifies the patching process, eliminating manual hex editing.
• Signature-Based: Uses AOB (Array of Bytes) signatures to locate the code to be patched, making the patcher more resilient to minor driver version changes.
• In-Place Patching: Patches the original files directly.
• Automatic Backups: Creates .bak backup files before patching, allowing easy restoration.
• Safety Checks:
  • Detects existing backups and prompts the user to restore, skip, or abort to prevent accidental double-patching.
  • Includes a check for administrator privileges and warns the user if they are not running with sufficient permissions.
• Error Handling: Provides informative error messages to guide troubleshooting.
• Clear Output: Displays a summary of the patching process, including successes, skips, and failures.

Prerequisites

• Python 3.x: You need Python 3 installed on your system if you will be running the python script instead of the release binary. You can download it from https://www.python.org/downloads/
• Original Driver Files: The script must be run in the root installation directory of the Alternative A2DP Driver.

How to Use

For the Release Binary (.exe) - Recommended Method

1. Download: Go to the Releases page and download the latest .exe file.
2. 2. Place the Patcher: Copy the downloaded .exe into the root installation directory of the driver (typically C:\Program Files\Luculent Systems\AltA2DP).
3. Run as Administrator: Right-click on the .exe file and select "Run as administrator". This is required to modify files in the Program Files directory.
4. Follow Prompts: The patcher will guide you through the rest of the process.

For the Python Script (.py)

1. Prerequisites: Ensure you have Python 3 installed.
2. Download: Download the patcher.py script from the repository.
3. Place the Script: Copy patcher.py into the driver's root installation directory.
4. Open an Admin Terminal: Open Command Prompt or PowerShell as an Administrator.
5. Run the Script: Navigate to the installation directory in the terminal and run the script using the command: python patcher.py

How to Restore the Original Driver

If something goes wrong or you want to revert the changes, you can restore the original driver from the backup files:

1. Locate the .bak files in the installation directory (e.g., AltA2dpConfig.exe.bak and AltA2DP.sys.bak in the Driver subfolder).
2. Delete the patched files (AltA2dpConfig.exe and AltA2DP.sys).
3. Rename the .bak files to remove the .bak extension. For example, rename AltA2dpConfig.exe.bak to AltA2dpConfig.exe.

Troubleshooting

• "Permission denied" error: This means you are not running the script as an administrator. Right-click on the binary and select "Run as administrator" or make sure the cmd window/powershell window from which you ran patcher.py was also ran as an administrator.
• "Signature not found" error: This indicates that the script could not find the expected code pattern in the file. This can happen if:
  • The original files have already been patched. Try restoring from the .bak files first.
  • You are using a different version of the Alternative A2DP Driver than the script is designed for.
• Script does not create .bak file - This is due to a permission error where the script lacks access to create files in the installation directory. Running as an admin will usually resolve this issue.
