Re-open your Delphi software, set the hardware configuration to match this COM port, and click . 3. Diagnose Physical Hardware and USB Power Issues
: Connect the VCI unit to a vehicle's OBDII port or a stable 12V power supply. Do not rely solely on USB power, as it may fluctuate during the flash process.
: For users of "clone" devices, connecting to the internet during an update can trigger security protocols that disable the device's drivers. Strategies for a Successful Update
Do not use a USB hub. Connect directly to a USB 2.0 port on your computer, as USB 3.0 can sometimes cause issues. Ensure Proper Power: Connect the
: Security applications often isolate or block the serial execution files needed to safely write firmware to the VCI chipsets. delphi+ds100e+firmware+update+problem+work
Connect the DS100E/DS150E to the vehicle (12V) and to your laptop via the (avoid hubs).
: Expand the Ports (COM & LPT) section. Look for VCI (Diagnostic Unit) or USB Serial Port . Change Port Settings : Right-click the port →right arrow Properties →right arrow Port Settings tab →right arrow Advanced .

: If you are using a newer software version (e.g., 2017.3 or 2021.10b), you must update to a matching firmware version, such as v1622 , for full vehicle compatibility. Re-open your Delphi software, set the hardware configuration
Fixing firmware update issues with the (Autocom/VCI) usually involves resolving a mismatch between the software version and the hardware's internal firmware. When the update fails or the device isn't recognized, it typically manifests as a "Communication Error" or a frozen progress bar. Common Causes of Update Failure
Navigate to your primary working diagnostic directory (e.g., C:\Program Files (x86)\Delphi Diagnostics\Delphi Cars\ ). Locate the folder named .
: Plug the OBD2 end into a healthy car battery or a stable 12V desktop power supply. The USB port alone does not always provide enough current to complete a flash. 2. Synchronize the Firmware Folders
The Delphi DS100E (also sold as the or Bosch ADS 100 ) is a popular professional J2534 Pass-Thru interface. It supports: Do not rely solely on USB power, as
When standard firmware refuses to cooperate, modified custom firmware can be a lifesaver, particularly for clone DS100E units. Users have reported success with firmware 1622 modified to work with all Delphi and WOW (Wurth) software. After obtaining the correct modified firmware file, add it to the firmware folder and initiate the update process. This approach has successfully restored many devices that standard updates had bricked.
: The VCI unit must be connected to a 12V power source (usually a vehicle’s OBD port) while updating; relying solely on USB power often leads to failure.
Before executing the fixes, it helps to understand why the firmware update fails, freezes, or fails to initiate:
Wait for the LEDs on the device to stop flashing (usually turning solid blue or green) before disconnecting. If the Device is "Bricked"
Flashing freezes; 9241A chip incompatibility; missing components.
