• A JTAG programmer (like Segger J-Link or ST-Link).
• Soldering to the test points on the PCB.
• Flashing the original bootloader hex file.

Unless you are an electronics hobbyist, send the device to a specialist repair service (cost: ~$50–80). This review is based on common user experiences

4. Manual Bootloader Mode (For Semi-Bricked Units)

If your DS100E shows a solid red light or is unrecognized: Last Resort: JTAG Recovery If your DS100E is

• Step A: Disconnect the device.
• Step B: Press and hold the “OK” button (or the button next to the LCD, depending on version).
• Step C: While holding the button, plug the USB cable into the PC.
• Step D: Release after 5 seconds. The device should now enter “Bootloader Mode” – recognized as a generic HID or DFU device.

Step-by-Step Prevention Guide (Before Updating)

1. Identify your device type – Use “Delphi Device Checker”. If serial is “1234567890” or all zeros, it’s a clone.
2. Backup current firmware using ST-Link Utility (requires SWD pins).
3. Disable Windows Driver Signature Enforcement (for Windows 10/11).
4. Use a powered USB hub – Never update through a laptop’s unpowered port.
5. Turn off antivirus – Some updaters flag patched DLLs as false positives.
