If you are running the latest 2020/2021 software suite but have older hardware, the firmware link will fail. It is often recommended to install the software version that matches the age of your hardware. For many DS100E users, rolling back to the 2016.R0 or 2015.R3 software suite resolves the firmware link issues immediately, as these versions have stable update pathways for the older hardware.
If you have a specific error message or a detailed issue you're facing during the update process, providing that information could help in giving a more targeted response.
If your Delphi DS100E (or similar CDP+ clone) is failing a firmware update, it’s usually due to a COM port mismatch or the software losing connection to the VCI. Common Solutions for Firmware Update Problems COM Port Selection
: The most frequent fix involves manually selecting the correct COM port in the software settings. Ensure you have the device connected via USB, go to the hardware setup/test section, select the correct COM port (often 9 or 20 depending on your PC), and click "Test" before attempting the "Update Firmware" button. Forced Firmware Update
: If the device is "stuck" or the application can't find it at all, it may have lost its stable firmware due to a power glitch. In these cases, connecting the VCI strictly via USB and using the "Hardware Setup" tool within the Delphi software can often "force" a fresh flash. "No VCI Found" Error
: If you see a "No VCI" error during the process, it usually indicates a driver issue or an incorrect firmware file in your installation folder. You can often troubleshoot this by ensuring your PC's Device Manager recognizes the "Autocom USB" or "Delphi VCI" device correctly.

1. Server-Side Obsolescence The most common cause for the "link" error on older genuine units and cloned units is that the specific firmware update servers for the DS100E hardware revision have been depreciated or moved. As Delphi (now settled under the CARS and TRUCKS brand umbrella) pushes newer hardware like the DS150E v2 or BlueTech adapters, support pathways for older DS100E units are sometimes orphaned. delphi ds100e firmware update problem link
2. Driver Confusion (The "Clone" Factor) A vast number of DS100E units in circulation are high-quality clones. These units often require specific, hacked driver files to communicate with the PC suite. If you update the main software suite to a version newer than what the cloned hardware supports, the software will try to fetch official firmware that is incompatible with the clone's architecture, resulting in a failed link.
3. USB Port Instability Firmware updates are sensitive to data interruption. If you are using a USB hub, a low-quality cable, or a USB 3.0 port that has backward-compatibility issues with the older drivers, the "link" will drop during the heavy data transfer of the update.

The Delphi DS100E (and its successor, the DS150E) is a critical tool for vehicle diagnostics, but firmware update issues can effectively "brick" the device if not handled correctly. Resolving a firmware update problem typically involves ensuring stable power, correct COM port configuration, and manual file management within the Delphi software environment. Common Causes of Firmware Update Failures
Updating the firmware on a Delphi VCI (Vehicle Communication Interface) often fails due to simple environmental factors:
Insufficient Power: The VCI must be connected to a stable 12V power source (usually the vehicle's OBD-II port) and the laptop via USB simultaneously.
COM Port Mismatches: If the software cannot find the VCI, it may be looking at the wrong COM port. This is a primary cause of the "No VCI Found" error.
Software version conflict: Using newer software with older firmware (or vice versa) often triggers a mandatory update prompt that can hang if the firmware files are missing or corrupt. Step-by-Step Resolution Guide
If your update is stuck or failing, follow these steps to force a successful sync: 1. Establish a Stable Hardware Connection
Plug the DS100E into a vehicle's OBD port to ensure it has 12V power.
Connect the VCI to your laptop using a high-quality USB cable. Avoid using long extensions or hubs, as signal loss can interrupt the flashing process. 2. Configure the Hardware Setup
Open your Delphi software and navigate to Settings > Hardware Setup.
Select the correct COM port. If you are unsure which port to use, check your PC's Device Manager under "Ports (COM & LPT)" to see which one is assigned to the Delphi VCI.
Click the Test button. You should see a confirmation that the VCI is found, even if it says the firmware is outdated. 3. Execute the Manual Update Key problems
Once the test is successful, click the Update button within the Hardware Setup menu.
During the update, the LED on the device will typically flash (often red or blue). Do not disconnect the cable or turn off the vehicle during this time, as it can corrupt the internal memory. Troubleshooting "No VCI Found" during Update
If the software still fails to recognize the device, you may need to manually point it to the firmware files:
File Path: Ensure the firmware files are located in the Firmware folder within your main Delphi installation directory (e.g., C:\Program Files (x86)\Delphi\Firmware).
Force COM Port: Some users have found success by forcing the COM port to a specific number, such as COM 28, in the Windows Device Manager to clear communication conflicts.
Security Software: Temporarily disable antivirus software or firewalls, as these can sometimes block the low-level data transfer required to flash firmware. Official Resources and Documentation

If the software cannot automatically download the firmware due to a server link error, you can often force the update manually.
The firmware update process for the DS100E involves the diagnostic tablet communicating with a PC suite (usually Delphi’s DS150E software) to transfer new operating instructions to the device's hardware.
The "bad link" or "file not found" error typically manifests in one of two ways:
You have the link, but pasting it into a browser won't fix the device. You must perform a "Cold Flash Recovery."
