What to do when the Biometric Wallet screen gets stuck during a firmware update

First, disconnect your D’CENT wallet from your computer.

Press and hold both the "Down (v)" button + "Power" button for few seconds to force the device to power off. If your device is "brick"ed during the firmware update, you can still access the bootloader mode by pressing and holding both "OK" button + "Power" button for 10 seconds.

From the bootloader mode, you can try updating the firmware to recover your Biometric Wallet.

What to do when the Biometric Wallet is not recognized by the PC

What should I do from the Device Manager?

From the Device Manager screen, look for "Human Interface Devices".

Check if there is a "USB Input Device" marked as error (yellow triangle with exclamation mark). You will need to check if this is indeed a D'CENT device.

Right Mouse Click on this device and select "Properties".

• From the USB Input Device Properties window, select "Details".

• Under Property, choose "Hardware Ids".

• Correct device ID for D'CENT is "PID_2130", "PID_2131" or "PID_2141".

From the "Device Manager", Right Mouse Click on the error marked device and select "Uninstall device".

On the top menu of Device Manager, press Action then select "Scan for hardware changes". This will scan for any new devices attached and will automatically install the driver to detect your Biometric Wallet.
