For automotive professionals specializing in Mercedes-Benz vehicles, maximizing performance and accessing advanced functionalities are paramount. The DAS Xentry Bypass HW tool emerges as a crucial solution, enabling technicians to overcome factory-imposed limitations and fully leverage the diagnostic and programming capabilities of the DAS (Diagnostic Assistance System) and Xentry software suite. This article delves into the significance of DAS Xentry Bypass HW, its applications, and provides a step-by-step guide on integrating it within a DAS Xentry 01/2014 installation.
Understanding the Need for DAS Xentry Bypass HW
Mercedes-Benz vehicles, like many modern automobiles, are equipped with electronic control units (ECUs) that govern various aspects of vehicle operation, including engine performance, speed limits, and other functionalities. While these limitations serve regulatory and manufacturer-specific purposes, automotive experts often require the ability to bypass these restrictions for diagnostic, tuning, and advanced repair procedures.
The DAS Xentry Bypass HW serves precisely this need. It’s a supplementary tool designed to work in conjunction with Mercedes-Benz DAS and Xentry diagnostic software, specifically targeting limitations on maximum speed (Vmax) and engine torque. By implementing this bypass, professionals gain unrestricted access to performance parameters, facilitating comprehensive diagnostics, performance optimization, and specialized repairs that would otherwise be constrained.
Step-by-Step Guide: Installing DAS Xentry 01/2014 and Integrating Bypass HW
The following guide outlines the process of installing DAS Xentry version 01/2014 and incorporating the DAS Xentry Bypass HW. This procedure assumes a foundational understanding of software installation and computer partitioning.
Preparation Phase:
- Boot from Installation Media: Begin by booting your computer from a bootable CD/DVD or USB drive containing the Windows XP installation files.
- Partitioning Hard Drive: During the Windows XP installation process, configure the partition sizes as follows:
- C partition: Allocate 20 GB (for Windows XP installation).
- D partition: Allocate 6 GB (can be larger, but not smaller).
- E partition: Allocate 20-25 GB.
- F partition: Allocate 30 GB.
- Windows XP Installation: Install Windows XP on the C partition, using NTFS formatting (avoid quick format for thoroughness).
- User Account Creation: Upon completion of Windows XP installation, create two user accounts: “STAR” and “OWNER”. Log into both accounts.
- Format Partitions D, E, and F: Return to the “STAR” user account and format partitions D, E, and F using NTFS. Quick format is acceptable here.
- Set System Date: Adjust the system date to a date in November 2013 (e.g., November 10th, 2013).
- Driver Installation (Optional): Install necessary hardware drivers. While optional at this stage, driver installation might be deferred until after DAS/Xentry installation to prevent potential conflicts.
- Install Disc Image Tool: Download and install a CD/DVD image tool like PowerISO. Ensure “autostart” and “automount” options are enabled within the tool’s settings.
- Install Acrobat Reader (Optional): Install Adobe Acrobat Reader (version 7.0.8 is suggested) to prevent potential errors during the initial DVD installation. If not installed, a harmless error might appear, which can be ignored.
- Disable Windows File Protection: Navigate to the “NewGuide2i” folder (ensure you have this tool downloaded; search online if needed) and run “WFPswitch” application to disable Windows File Protection. Click “Quit” and restart your PC.
WBEMTEST Configuration (Crucial Step):
- Open WBEMTEST: Go to Windows Start > Run, type “wbemtest,” and press Enter.
- Connect to Namespace: In the WBEMTEST window, click “Connect.” In the subsequent window, type “rootcimv2” and click “Connect.”
- Open Instance: Click “Open Instance,” type “Win32_ComputerSystem,” and press Enter.
- Delete Manufacturer and Model: Locate and delete the “Manufacturer” and “Model” properties.
- Add “Manufacturer” Qualifier: Click “Add qualifier.” In the Qualifier Editor window, enter “Name: Manufacturer” and “Value: adstec.” Click “Save Qualifier.”
- Add “Model” Qualifier: Click “Add qualifier” again. Enter “Name: Model” and “Value: C4TT13.” Click “Save Qualifier.”
- Save Object: Crucially, click the “Save Object” button to ensure all WBEMTEST modifications are saved.
- Restart PC: Restart your computer.
Post-Restart Configuration and Installation:
- Run “prepare.bat”: Navigate to the “NewGuide2i” folder and execute “prepare.bat.”
- AppID 253 Folder: Once “prepare.bat” completes and prompts for a restart, do not restart immediately. Navigate to the “AppID 253” folder (ensure you have this; search online if needed) and copy the folder to the Startup folder. Refer to the detailed instructions within the “AppID 253” folder for precise steps. After copying, return to the “NewGuide2i” command prompt and confirm the restart.
- License Activation: After restarting, open Star Utilities and input licenses for Xentry, DAS, and WIS. License key generators (“keygens”) can be found online if needed.
- Launch Hardware Monitor: Open the “Das_xentry_bypass_hw” folder and run “HardwareMonitor.exe.”
- Mount First DVD: Mount the first Star Diagnosis DVD (DVD from July 2013, “SD_DVD_07_2013_1”).
- Start Installation (DVD 1): Initiate the installation by running “setup.exe” from the mounted DVD drive (e.g., X:stardiagsetup.exe).
- Xentry License Entry (AppID 253 Trigger): Due to the AppID 253 configuration, you will be prompted to enter a new Xentry license. Provide the license when requested.
- “javaws.exe” Error (Potential): You might encounter an error message stating that “javaws.exe” has crashed. Click “Don’t send.” You may be prompted to enter the Xentry license and encounter the “javaws.exe” error repeatedly. This is expected due to the WBEMTEST modifications. Continue through these prompts until an error report appears in Star Utilities. Close the error report and proceed with the installation. The installation should conclude shortly after, prompting for a restart. Click “Finish” and restart your PC.
- License Entry Post-Restart: After Windows restarts, open Star Utilities and enter the new Xentry license key again. This time, the AppID should be 253.
- Launch Hardware Monitor (Again): Re-open the “DAS_Xentry_byPass_HW” folder and run “HardwareMonitor.exe.”
- Start Installation (DVD 1 – Second Attempt): Initiate the installation again from the mounted DVD drive (e.g., X:stardiagsetup.exe). This second attempt should proceed smoothly.
- Mount Second DVD: Upon successful completion of the first DVD installation, mount the second Star Diagnosis DVD (DVD from November 2013).
- Start Installation (DVD 2): Begin the installation from the second DVD. You can either repeat the process from the DVD drive or utilize a desktop shortcut that might appear to initiate the second DVD installation.
- Run “after installation.bat”: After the second DVD installation completes, do not click “Finish” immediately. Navigate to the “NewGuide2i” folder and run “after installation.bat.”
- Finish Installation and Restart: Once “after installation.bat” finishes, click “Finish.” The PC will restart and install hotfixes.
Undo WBEMTEST Modifications (Final Step):
- Reverse WBEMTEST Changes: Undo the WBEMTEST modifications performed earlier. As described by user “phara0n”:
- Remove the “Manufacturer” and “Model” qualifiers you added.
- Add “Model” and “Manufacturer” properties back using “Add property.”
- Set the value for both “Model” and “Manufacturer” properties to “NULL” (as they were originally).
- Restart PC: Restart your computer to finalize the process.
