Confirm that your hardware explicitly matches the d00012 revision profile. Flashing this onto a d00011 or d00013 unit will cause an instant hardware fault.
Navigate to your device's hardware management console or system settings layer. Choose or Firmware Upgrade via File . Keep the system completely still and connected to uninterrupted power throughout the 15-to-30 minute flashing window to avoid data corruption. Step 4: Re-index and Validate the Database
To ensure that your device has fully integrated the update and is operating securely, follow these deployment steps depending on your platform: Via Windows Device Manager Open the and search for Control Panel . Click on System and Security , then select Device Manager .
