Open the folder labeled . Copy all contents inside this folder (usually containing various .hex or .bin binaries).
After a failed update, the software no longer recognizes the device via USB or Bluetooth.

Allow the software up to 5 full minutes to finalize the write sequence. Do not move the cables or shut off the computer until a success window states that firmware version 1622 (or your selected equivalent) has been successfully verified. Best Practices for Stable Delphi VCI Updates
Often, the problem isn't the firmware, but the FTDI drivers . If the computer sees the DS100E as a "Generic Serial Port" rather than a "Delphi Diagnostics" device, the firmware update will never initiate. Reinstalling the drivers manually through Device Manager is a frequent fix. Open the folder labeled
If the device stays red after a failed update, try restarting both the software and the VCI, ensuring the 12V power supply is stable.
The is a staple in many automotive workshops, valued for its ability to communicate with a wide range of vehicle ECUs . However, the device often hits a wall during firmware updates—a process intended to keep the hardware compatible with newer software versions (like V2020.23 or V2021). When a firmware update fails, it typically leaves the device in a "dead" state, or prevents it from connecting to vehicles entirely. The Core of the Problem Do not move the cables or shut off
Ensure your software license matches your exact VCI serial configuration (such as the standard 6-digit identifiers).
If the software says "VCI not found," your computer isn't talking to the hardware.
