The tool should detect the drive. Select "Production" or "Restore" to flash the controller firmware and format the NAND memory.
The controller has locked the NAND flash memory to protect existing data after detecting too many bad blocks or a physical voltage drop.
When a flash drive with the VID 1E3D & PID 198A profile malfunctions, it rarely suffers from physical hardware death. Instead, the flash memory translation layer in the controller fails, resulting in several classic symptoms:

To find the USB\VID_1E3D&PID_198A entry on your system:
When a Chipsea MCU (e.g., CSU38F20) is placed into bootloader mode (e.g., by pulling a specific pin low on reset), it enumerates as VID:1E3D PID:198A . In this state:
USB Device ID VID 1E3D PID 198A, Chipsailing driver, fingerprint sensor driver, 1e3d 198a driver, Windows Hello unknown device. The tool should detect the drive

If you have tried all the steps above and the device still does not work, it may be a hardware failure. Fingerprint sensors have limited write cycles and can fail after 2–3 years. In that case, disable the device in Device Manager or replace the module if your laptop supports it.
