This process ensures that you have the latest features and security patches, which are vital for protecting your digital assets. In this guide, we will walk you through the detailed steps required to update the firmware version of your Trezor device, ensuring that you do not miss any critical steps along the way.

Preparing for the Firmware Update

Before you begin the firmware update process, it is essential to take a few preparatory steps to ensure a smooth and successful update. Here are the steps you need to follow:

• Ensure your Trezor device is fully charged or connected to a power source. This prevents any interruptions during the update process that could potentially brick your device.
• Backup your recovery seed. Although the firmware update should not affect your wallet's data, it is always a good practice to have a backup of your recovery seed. This can be found on the Trezor device itself.
• Connect your Trezor to a computer with a stable internet connection. The update process requires downloading the latest firmware from the Trezor website, so a reliable internet connection is necessary.

Accessing the Trezor Bridge

The Trezor Bridge is a software component that facilitates communication between your Trezor device and the Trezor Wallet application on your computer. To update the firmware, you need to ensure that you have the latest version of the Trezor Bridge installed. Here's how to do it:

• Open your web browser and navigate to the Trezor website. Look for the "Downloads" or "Support" section where you can find the latest version of the Trezor Bridge.
• Download and install the latest Trezor Bridge. Follow the on-screen instructions to complete the installation. Once installed, the Trezor Bridge will run in the background, allowing your Trezor device to communicate with the Trezor Wallet application.

Launching the Trezor Wallet Application

With the Trezor Bridge installed and running, you can now launch the Trezor Wallet application to initiate the firmware update process. Here's how to do it:

• Open the Trezor Wallet application on your computer. You can download it from the Trezor website if you haven't already installed it.
• Connect your Trezor device to your computer using the USB cable. The Trezor Wallet application should detect your device and prompt you to enter your PIN.
• Enter your PIN on the Trezor device. This will unlock your device and allow you to access the wallet interface.

Initiating the Firmware Update

Once your Trezor device is connected and unlocked, you can proceed with the firmware update. Here are the steps to follow:

• In the Trezor Wallet application, navigate to the "Settings" or "Device" section. Look for an option that says "Firmware Update" or something similar.
• Click on the "Firmware Update" option. The application will check for the latest firmware version available for your device.
• If an update is available, the application will prompt you to proceed with the update. Click on "Update" to start the process.

Completing the Firmware Update

The firmware update process will now begin. It is crucial to follow the on-screen instructions carefully to ensure a successful update. Here's what you need to do:

• The Trezor Wallet application will download the latest firmware from the Trezor servers. This may take a few moments, depending on your internet connection speed.
• Once the firmware is downloaded, the application will prompt you to confirm the update on your Trezor device. Follow the instructions on the device's screen to confirm the update.
• The Trezor device will now begin the firmware update process. Do not disconnect the device or interrupt the process in any way, as this could damage your device.
• Once the update is complete, the Trezor device will restart automatically. The Trezor Wallet application will notify you that the firmware update was successful.

Verifying the Firmware Version

After the firmware update is complete, it is a good practice to verify the new firmware version to ensure that the update was successful. Here's how to do it:

• In the Trezor Wallet application, navigate to the "Settings" or "Device" section. Look for an option that says "Firmware Version" or something similar.
• Click on the "Firmware Version" option. The application will display the current firmware version installed on your Trezor device.
• Compare the displayed firmware version with the latest version available on the Trezor website. If they match, then the firmware update was successful.
