1. SDConnect Toolkit: Look at the Toolkit icon in your system tray. Is the C4 detected and does it have a green checkmark? If the Toolkit does not see the mux, DAS cannot use it. Check your IP settings (PC IP should be 172.29.127.119, Subnet 255.255.0.0).
2. Blacklist Fix: Since you are using the FullFix, re-run the tool and ensure you have applied the C4 Blacklist раtсh (sometimes labeled as "Mux Fix" or similar). If your clone C4 serial number is on the blacklist, DAS will throw this error.
3. Configuration: Check the file cal.ini in C:\Program Files (x86)\Mercedes-Benz\DAS\bin\. Ensure the platform is set correctly for C4 (usually PLATFORM=PART_D2).

DAS\bin\ cal.ini change "PLATFORM=PART_T"

• PART_T is strictly for PassThru (J2534) devices (like OpenPort, Scanmatik, etc.).
• PART_D2 is the correct setting for SDConnect C4.

PLATFORM=PART_D2

This usually happens if a background service fails to start or a patched file was blocked by the system.

Please check the following points:

• Secure Boot: Go into your BIOS and make sure Secure Boot is Disabled. The раtсh uses modified DLLs that often fail to load if Secure Boot is active.
• Antivirus: Check Windows Defender or your AV history. It likely quarantined a file in
  Code:

  C:\Program Files (x86)\Mercedes-Benz\Xentry\bin

  (usually a DLL related to authentication or the diag service).
• Services: Open
  Code:

  services.msc

  and check if the Xentry Diagnosis Service is running. If it is stopped, try to start it manually.

If it still hangs, try re-applying the FullFix as Administrator, but make sure your antivirus is disabled during the process.

First, I assume you mean 03.2024 (or perhaps 12.2023), as 03.2026 does not exist yet.

Since the 2023 updates, Mercedes has completely removed the "Offline Mode" button and the ability to use z / z from the standard interface. A clean installation will always force you to the Online B2B login screen.

To get the offline option back, you must apply the specific раtсh for it. Since you are in the Samik FullFix thread:

1. Run XENTRY FullFix By Samik as Administrator.
2. Look for the checkbox or button labeled Offline Login or Common Fixes (depending on your version of the tool).
3. Apply the fix.

This раtсh modifies the internal login.html and JavaScript files to restore the offline button or bypass the login screen entirely.

If you have already applied the fix and the button is still missing:

• Check your Antivirus/Defender history. It often detects the modified login.js or Authentication dlls as threats and restores the original files.
• Ensure you are using a version of the FullFix that supports your specific Xentry version. Older fixers often don't work on 2024 installations because the file structure of the login page changed.

Can you do full run off how to install xentry by samik v4.8.1 on windows 10 pro.

Click to expand...

• 1) Prepare Windows
  • Use Windows 10 Pro (64-bit) (preferably clean install / minimal background apps).
  • Log in as your main user (preferably an account with admin rights).
  • Connect your internet only if the installer requires it for login components; otherwise you can disconnect after the installation steps that need it.
• 2) Install as Administrator
  • Right-click the FullFix installer and choose Run as administrator.
  • Don’t run it through VM/compatibility mode.
• 3) Choose Components
  • In the custom installer, select the required parts.
  • Common selections people use:
    • XENTRY Open Shell
    • Vediamo (pick version if prompted)
    • DTS Monaco (if shown/needed)
    • Special Functions / FDOK Calculator (and other calculator/unlock tools if you want them)
    • Any helpers (SW Finder, Add-on Blocker, etc.) if you want a “full” toolset
• 4) Install / Let it finish
  • Let the installer complete all steps.
  • If there are driver prompts (J2534/Passthru drivers), allow/install them when shown.
• 5) Offline / Online Login behavior (important)
  • With newer XENTRY versions, a clean install typically forces you to the Online B2B login screen.
  • If you want offline login back, apply the Offline Login / Common Fixes option included in the FullFix “fix” area:
    • Run the FullFix tool as Administrator.
    • Find the checkbox/button labeled Offline Login or Common Fixes (label may vary by build).
    • Apply the раtсh/fix.
• 6) First start + update prompts
  • Launch XENTRY components.
  • If it asks for updates/components, follow the prompts carefully (don’t cancel mid-way).
  • If you get login issues, re-check whether offline fix is applied correctly.
• 7) PassThru / Interface setup (J2534)
  • Plug in your interface after installation (or as requested by installer).
  • Confirm the passthru drivers are installed (VX Manager / Scanmatik / Openport, etc. depending on what you use).
• 8) Test before coding/flashing
  • Run a quick module scan / basic diagnostics first.
  • Only proceed to ECU/coding after you confirm stability.

• What passthru/interface you use (VX Manager / Scanmatik / Openport 2.0 / other)
• Whether your Windows is already installed or you’re doing a clean install

Ton1, yes—if your Windows 10 Pro is already installed, you don’t need to reinstall Windows. You just install the Samik FullFix package and (optionally) apply the offline/login fix.

Do this:

• Prepare Windows]
  Install/update the basics (VC++/NET if prompted), and keep it clean: disable unnecessary startup apps.
• Run the installer correctly]
  Copy the FullFix v4.8.1 installer to the PC, right-click it → Run as administrator.
  Don’t run in VM.
• Install required components]
  In the custom installer, select the tools you need (at least XENTRY Open Shell, plus Vediamo/DTS Monaco if you want coding/engineering features).
• Install J2534 drivers]
  If you’re using SM2 Pro / passthru, install the drivers when the installer asks (choose the matching passthru option in the installer).
• Offline vs Online login]
  If after install you only get Online B2B login, run FullFix as Administrator and apply the option labeled Offline Login / Common Fixes (wording can vary).

Quick questions so I can guide you exactly:

• What is your SM2 Pro</b] interface connected as (which mode/model/driver name)? (or post a screenshot of the driver list in FullFix)
  [*]Do you want offline login working, or is online login OK?
  [*]Are you on Windows 10 22H2 (or which build)?

scanmatik version 2.21.32 build 04.02.2025 offline work on windows 10 pro 22h2 build 19045.6466

Click to expand...

• Install VC++/.NET prerequisites if FullFix asks (leave them to install).
• Run the FullFix v4.8.1 installer as Administrator (right-click → Run as admin).
• In the custom component list, at minimum install: XENTRY Open Shell.
• Do not run FullFix in VM.
• After install: if you still see only online B2B login, run FullFix tool (as Admin) and apply the option Offline Login / Common Fixes (wording may differ).

1. Do you want XENTRY to be fully offline (no login), or only want it to launch without issues?
2. Is SM2 Pro connected to the PC via USB passthru/J2534—what driver/mode does it show in Device Manager after you plug it in?

Gemini said:

Ton1, yes—Scanmatik 2 works fine on Windows 10 Pro 22H2 (19045.6466). For XENTRY FullFix v4.8.1, the key point is not Scanmatik version, but making sure your OS/tools don’t conflict and that you apply the correct offline-login option.

Do this:

• Install VC++/.NET prerequisites if FullFix asks (leave them to install).
• Run the FullFix v4.8.1 installer as Administrator (right-click → Run as admin).
• In the custom component list, at minimum install: XENTRY Open Shell.
• Do not run FullFix in VM.
• After install: if you still see only online B2B login, run FullFix tool (as Admin) and apply the option Offline Login / Common Fixes (wording may differ).

Quick check for me so I guide you correctly:

1. Do you want XENTRY to be fully offline (no login), or only want it to launch without issues?
2. Is SM2 Pro connected to the PC via USB passthru/J2534—what driver/mode does it show in Device Manager after you plug it in?

sm2 j2534 device configurator offline without issues . install complete steps

Click to expand...

• Run XENTRY FullFix (or the FullFix launcher) as Administrator.
• In the FullFix tool/menu after install, apply the Offline Login / Common Fix option (in your case it sounds like the option is the one shown as “O”).
• After applying the offline option, reboot the PC.
• Open XENTRY Open Shell (run as Admin) and let it finish database/loading.
• Plug in SM2 Pro and confirm the passthru driver is still working (device stays detected, no driver errors).
• Try opening a vehicle/ECU from Open Shell and start a session (even just a quick scan) to verify communication.

Gemini said:

Ton1, if your SM2/J2534 works offline and install is complete, then the remaining “XENTRY FullFix” steps are only about getting the right offline login/config for XENTRY.

Do this in order:

• Run XENTRY FullFix (or the FullFix launcher) as Administrator.
• In the FullFix tool/menu after install, apply the Offline Login / Common Fix option (in your case it sounds like the option is the one shown as “O”).
• After applying the offline option, reboot the PC.
• Open XENTRY Open Shell (run as Admin) and let it finish database/loading.
• Plug in SM2 Pro and confirm the passthru driver is still working (device stays detected, no driver errors).
• Try opening a vehicle/ECU from Open Shell and start a session (even just a quick scan) to verify communication.

To be sure I tell you the exact clicks: when you run the FullFix tool, what does the offline/login menu show (screenshot or exact option names/numbers)? Also confirm you’re using the J2534 Device Configurator successfully before launching XENTRY.

is this the complete v4.8.1 install or only xentry, i would like complete install

Click to expand...

• Run the FullFix v4.8.1 installer as Administrator.
• In the custom/component list, select at minimum:
• XENTRY Open Shell (must-have to work with SM2/J2534)
• Also install any prerequisites that the installer prompts (VC++/.NET).
• If you want “complete” for coding/diagnostics, also select the additional components like Vediamo and/or DTS Monaco (if shown in the list).
• Then after install, run the FullFix tool/launcher and apply the Offline Login / Common Fix option (the “O” option).
• Reboot PC, then launch XENTRY Open Shell as Admin and let it finish DB/loading.

• “install everything available in the FullFix component list” (all modules), or
• “XENTRY fully working + SM2 passthru offline” only?

Ton1 said:

yes

Click to expand...

• All XENTRY-related modules (including XENTRY Open Shell)
• Any prerequisites/components the installer offers (VC++/.NET etc.) -> leave them enabled
• Optional but “complete” add-ons it shows (e.g., Vediamo / DTS Monaco if present)
