: The software might be looking for the device on the wrong port. Forcing the connection on a specific port (e.g., COM 28 ) has been cited as a common fix for clones.
The diagnostic software expects the VCI to be on a specific COM port (usually between COM 1 and COM 8). If Windows assigns a high port number (e.g., COM 24), the update link fails.
If the status LED on your DS100E flashes red continuously, the firmware chip is likely bricked from a partial flash.

The VCI uses FTDI drivers to simulate a serial connection over USB. Missing, outdated, or corrupted drivers break the data link.
Paste a known stable firmware version compatible with your device clone into this empty folder. (Versions like 1622 are widely considered the most stable for older double-board clones, while newer versions support single-board designs).

Disconnect the USB, run your verified driver installer, and reconnect the device. Step 3: Optimize COM Port Settings
Trusted firmware files are always bundled inside the installation directories of reputable diagnostic software providers. If your software copy is missing the firmware folder, reinstalling the core software release package is the safest way to recover the matching binary files.
By ensuring proper 12V power, checking your Windows COM port assignments, and matching the driver directory, you can easily bypass the link error and get your DS100E back to scanning vehicles. If Windows assigns a high port number (e
: Always connect the device directly to your PC via USB cable . Avoid using USB hubs or Bluetooth during a firmware update, as connection drops can "brick" the device.
Clone devices (which make up a large portion of DS100E units in use) often require specific firmware versions (e.g., 1622, 3201) that match their internal board architecture (single-board vs. double-board).
Manually browse to the Drivers folder within your Delphi software installation directory to reinstall the correct USB serial port drivers. In the Delphi software, go to Settings > Hardware Setup .
Before attempting fixes, it is essential to understand what disrupts the data link during a firmware update.
