The PC is using default Windows USB drivers instead of the dedicated FTDI drivers required by the DS100E hardware.
Use a Flash loader demonstrator to write the firmware file directly to the chip. Where to Find Firmware Update Files (Links)
Fixing Delphi DS100E Firmware Update Connection Failures The Delphi DS100E is a staple diagnostic tool for independent mechanics. However, updating its firmware often leads to communication errors. If your device is stuck in an update loop or shows a "Communication Error" link failure, you can resolve the issue using the steps below. Why the Firmware Update Fails
demonstrates how to navigate the COM port settings to ensure the update doesn't fail. Note on Versions : Ensure the firmware version in your software folder ( ...\Delphi\Firmware delphi ds100e firmware update problem link
If Windows cannot properly see the device, the Delphi update link will remain greyed out or fail instantly. Open on your Windows PC.
Open your Delphi installation directory (e.g., C:\Delphi CARS 2020.23\ or similar). Find the folder named .
The "bad link" or "file not found" error typically manifests in one of two ways: The PC is using default Windows USB drivers

The is a legacy diagnostic tool used by technicians for vehicle communication, but its aging infrastructure often leads to firmware update failures or "no link" errors during the synchronization process. These issues typically stem from improper power supply, driver conflicts, or incorrect COM port settings. Common Causes of Firmware Update Failures
The Delphi DS100E is a popular choice among independent mechanics and DIY automotive enthusiasts for its balance of functionality and affordability. However, a recurring headache for users is the firmware update process, specifically an error where the software claims it cannot find the update file or generates a "bad link" error during the firmware flash. However, updating its firmware often leads to communication
Updating the firmware on a Delphi VCI (Vehicle Communication Interface) often fails due to simple environmental factors:
If your Delphi DS100E is still not connecting after trying these steps, you may need to replace the USB connector inside the device itself, as this is a common point of failure. If you can tell me:
