Unfortunately, in about 2% of cases, the error is hardware-based. If you have performed all five fixes above and the error persists with the message "SWC not detected," the fingerprint sensor's internal ROM may have failed.

Look for these signs:

In this scenario, you must replace the fingerprint reader module or use a USB external fingerprint reader as an alternative.

sudo apt update
sudo apt install libfprint-2-tod1-goodix   # For Goodix sensors
sudo apt install libfprint-2-tod1-synaptics  # For Synaptics sensors

If all else fails, the Windows image itself may be corrupted. An "In-Place Upgrade" reinstalls Windows without deleting your files but repairs every SWC link.

This rewrites every driver component, including the missing SWC for the fingerprint sensor. In 95% of cases, this resolves the error permanently.

Understanding the cause is half the battle. This error does not typically indicate a hardware failure (though we will test for that). The primary culprits fall into four categories:

Ticket ID: FP-DRIVER-404 Type: Feature / Bug Fix Priority: High Component: Biometric Driver Core / Secure Element Interface
