Look for an item under or an Unknown Device with a yellow exclamation point. Right-click the item and choose Update Driver .
The DS100E runs a modified Android OS with a proprietary bootloader. During a firmware flash, the device writes critical system files to the NAND memory. At 99%, the system is usually verifying checksums or writing the boot configuration. If there is a voltage drop (even 0.5V) from the USB-C power supply, or a corrupted packet over WiFi, the verification fails. Unlike PCs, the DS100E has no rollback protection for the boot partition.
Connect the DS100E unit to a vehicle's OBD2 port OR a stable 12V bench power supply. Verify that the LED indicators on the hardware light up. Step 2: Configure the Device Manager Right-click the Windows Start menu and open . Expand the Ports (COM & LPT) drop-down menu. Look for the device labeled USB Serial Port .
Updating the Delphi DS100E (or DS150E) firmware is a common hurdle for DIY mechanics and technicians, often resulting in the dreaded "No VCI Found" error. This story breaks down the typical experience, the pitfalls of using clone hardware, and the steps to a successful fix.

To keep your automotive scanner functioning perfectly and prevent future update issues, adhere to these simple operating habits: Delphi DS150E Firmware Upgrade Procedure
: The update may freeze mid-way, often due to communication lag or incorrect COM port selection. Look for an item under or an Unknown
Before diving into the fixes, it’s important to understand that the DS100E firmware must match the version of the software (Autocom or Delphi) you are running on your PC. If you upgrade your software from version 2020.23 to 2021.11, the software will require a firmware "re-flash" to communicate with the hardware.
: The software may be looking at the wrong COM port, preventing it from communicating with the VCI. USB Connection Faults
Ensure your VCI is plugged directly into a live car OBD2 port. Never attempt a recovery flash on laptop battery power alone. During a firmware flash, the device writes critical
Solution 1: Supply 12V Power and Switch to a Direct USB Port
Ensure your laptop is plugged into a charger to prevent it from entering sleep mode or losing power. Verify COM Port Settings Open your Delphi software and navigate to Settings > Hardware Setup
If the device is unresponsive or flashing red, connect it via USB. In the software's Hardware Setup menu, click Update Firmware
and check for errors under "Ports (COM & LPT)" or "Universal Serial Bus controllers". If you see a driver error (Code 10 or 14), right-click and uninstall
Under the port configuration tab, look for your assigned COM port index. If communications fail, manually adjust your Windows advanced port assignments to force the tool onto .
