How to Download Xentry Developer Keygen 12 for Mercedes-Benz Diagnosis

Xentry Developer Keygen 12 is a software tool that allows you to unlock the developer mode in Xentry/DAS, the official diagnosis software for Mercedes-Benz vehicles. With developer mode, you can access more functions and features that are normally hidden or restricted by the manufacturer. For example, you can change coding, adaptation, variant coding, flash programming, and more.

If you want to download Xentry Developer Keygen 12 for free, you will need to follow these steps:

1. Register an account on MHH Auto, a forum dedicated to automotive software and tools.
2. Search for the thread “Fullfix/Patch for Xentry 2021-12 and newer [v4][upd.2021.12.07]” by disinfetor. This thread contains a link to download the full image of Mercedes-Benz diagnosis tools, including Xentry, DAS, EPC, WIS-ASRA, and the keygen.
3. Download the image file from the link provided in the thread. The file size is about 170 GB, so make sure you have enough space on your hard drive or external storage device.
4. Use Clonezilla or a similar software to restore the image file to a real HDD or a virtual machine. You will need to check the advanced options -icds and -k1 when restoring the disk in Clonezilla.
5. Run the keygen from the desktop shortcut and copy your hardware ID to the clipboard. The keygen will generate a license key and replace it in the clipboard. Paste the key in Xentry/DAS when prompted.
6. Enjoy the developer mode and explore more possibilities with your Mercedes-Benz diagnosis.

Note that these tools are hardware locked, so you might need to use a compatible device such as an SD Connect to connect to your vehicle. Also, be careful when using developer mode as it can cause irreversible damage to your vehicle if used incorrectly. Always backup your original settings before making any changes.

One of the benefits of using developer mode in Xentry/DAS is that you can access some hidden functions that are not available in the normal mode. For example, you can clean the ASSYST Plus memory, which stores the service history of your vehicle. This can be useful if you want to reset the service interval or erase the previous records. To do this, you need to enter the developer mode and select the ASSYST Plus module from the control units list. Then you can choose the option “Delete ASSYST PLUS Memory” and confirm your action.

Another benefit of using developer mode in Xentry/DAS is that you can view all the stored trouble codes in the control units, including the ones that are masked by the production software. This can help you diagnose some problems that are not detected by the normal mode. For example, you can check the error memory of the SRS module and see if there are any codes related to the airbags or seat belt tensioners. To do this, you need to enter the developer mode and select the SRS module from the control units list. Then you can choose the option “Read out error memory” and see all the codes displayed on the screen.

A third benefit of using developer mode in Xentry/DAS is that you can recode some parameters of the control units without needing a SCN (Software Calibration Number). This can allow you to customize some features of your vehicle according to your preferences. For example, you can change the speed limit of the cruise control, enable or disable some convenience functions, or adjust some settings of the instrument cluster. To do this, you need to enter the developer mode and select the control unit that you want to recode from the list. Then you can choose the option “Variant coding” and modify the values of the parameters as you wish.
