Sometimes the update is actually finished, but the software interface hangs. Force Restart:

If the update keeps failing at 0% or 100%, the issue is the USB stack.

If the "Update" button in the software settings is greyed out or fails:

“Fire it,” Leon said.

This is critical. . Do not rely solely on the USB port for power, as the peak current during flash writing can exceed what your laptop's USB port can provide.

He knew the root cause now. The v4.2.1 updater assumed the unit’s NAND flash had zero bad blocks. But the Odysseus’s unit, after three years of thermal cycles and salt-air corrosion, had nine. The update wrote the new bootloader over a worn-out sector, then panicked when the checksum failed—and erased its own escape hatch.

Navigate to your installation folder (e.g., C:\Program Files (x86)\Delphi Cars\Firmware ). delphi+ds100e+firmware+update+problem+work

Manually copy files over from the software installation folder. VCI not found on scan Force configuration to COM Port 28 via Device Manager. Low Voltage Update hangs mid-way

: Right-click your diagnostic software execution shortcut and select Run as Administrator to give Windows explicit permissions to execute direct COM port writing protocols.

Check your PC's Device Manager to identify which COM port the DS100E is assigned to. Sometimes the update is actually finished, but the

Delphi requires a specific, legacy FTDI driver. Windows 10 and 11 aggressively auto-update to newer FTDI drivers (3.x or 9.x). These newer drivers change the handshake protocol. If you connect the DS100E before installing the legacy driver, Windows installs the wrong one. The firmware update tool cannot see the device.

The Delphi software or Autocom software often looks for the device on an incorrect virtual COM port assignment.

These can block the communication between the software and the VCI. This is critical

Now, let’s move to the practical solutions.

Now run the firmware updater (Delphi_CDP_Firmware_Updater.exe). It should detect the device in recovery mode.
