How to update Trezor firmware

Keep your Trezor firmware updated for enhanced security, new features, and optimal performance—always use official sources and back up your recovery phrase before updating.

Jul 09, 2025 at 11:14 am

Understanding the Importance of Trezor Firmware Updates

Trezor firmware updates are essential for maintaining the security and functionality of your hardware wallet. These updates often include critical security patches, performance improvements, and new features that enhance user experience. Firmware is the software embedded in your Trezor device that controls its basic operations, so keeping it up to date ensures protection against potential vulnerabilities.

Users should always be cautious about where they download firmware from, as malicious versions can compromise wallet integrity. Only official Trezor sources should be used when updating firmware. This helps prevent phishing attempts or malware installation disguised as legitimate updates.

Preparing Your Device and Environment

Before proceeding with a firmware update, certain preparatory steps must be followed to ensure a smooth process. Ensure that your Trezor device is fully charged if applicable (this applies more to newer models like Trezor Model T). Additionally, use a trusted computer that is free from malware and has a stable internet connection.

You should also back up your recovery seed phrase before initiating any firmware update. While firmware updates typically do not erase wallet data, unexpected issues could arise. Make sure your recovery phrase is written down and stored securely, preferably offline and away from digital threats.

Accessing the Trezor Firmware Update Tool

To begin the firmware update process, you need to access the official Trezor firmware update tool. Visit the Trezor website and navigate to the "Downloads" section. Here, you will find the latest firmware version compatible with your specific Trezor model—either Trezor One or Trezor Model T.

Once you have downloaded the firmware file, connect your Trezor device to your computer using the provided USB cable. Open your web browser and go to the Trezor Suite application or use the legacy Trezor Bridge if necessary. Ensure that your browser allows communication with the Trezor device via WebUSB.

Initiating the Firmware Update Process

With your Trezor device connected and recognized by your computer:

  • Open the Trezor Suite application
  • Navigate to the settings or firmware update section
  • Check for available firmware updates

If an update is available, you will be prompted to proceed with the installation. Confirm the action on both your computer and your Trezor device. During the update, do not disconnect the device or close the browser window.

Your Trezor screen will display progress indicators during the firmware flashing process. This may take a few minutes, depending on your connection speed and device model. Once completed, your device will restart automatically with the new firmware version installed.

Verifying the Firmware Version After Update

After the update completes, it’s important to verify that the firmware was successfully applied. Go back into the settings menu within the Trezor Suite application and check the displayed firmware version. Compare this to the version number listed on the Trezor downloads page to confirm accuracy.

Physically check your Trezor device's screen for any error messages or prompts indicating success. If everything looks good, you can safely disconnect the device and resume normal usage. Should any issues arise, consult the Trezor support documentation or reach out to their customer service team for assistance.

A: No, firmware updates do not erase wallet data. However, it is still strongly recommended to back up your recovery phrase before performing any update to safeguard against unforeseen issues.
