Step-by-Step Device Update via Trezor.io/Start

Keeping your Trezor hardware wallet updated is essential for maintaining the highest level of security, compatibility, and performance. The most trusted method to update your device is through Trezor.io/Start — the official onboarding and maintenance portal for all Trezor devices.

Whether you’re updating a Trezor Model One or Trezor Model T, this guide will walk you through each step of the process clearly and safely.

Why Update Your Trezor Device?

Updating via Trezor.io/Start ensures:

• Protection against known vulnerabilities
• Access to the latest coin support and features
• Improved user interface and device responsiveness
• Compatibility with third-party tools like MetaMask, Electrum, or Trezor Suite

Most importantly, Trezor firmware updates do not affect your private keys or wallet funds, as those remain secured offline in the hardware itself.

What You Need Before You Begin

• Your Trezor device (Model One or Model T)
• A USB cable (original or high-quality data cable)
• A computer with a supported browser (Chrome, Firefox, Edge, Brave)
• Trezor Bridge installed (unless using Trezor Suite desktop)
• Stable internet connection
• Optional: Your recovery seed stored safely nearby (not needed unless something goes wrong)

Step-by-Step: Updating via Trezor.io/Start

Step 1: Go to Trezor.io/Start

Open your browser and navigate to: https://trezor.io/start

You’ll be prompted to choose your device model. Select either:

• Trezor Model T
• Trezor Model One

Then, follow the on-screen guidance to begin the device connection process.

Step 2: Install Trezor Bridge (If Prompted)

If you haven’t installed Trezor Bridge before, the site will detect this and prompt you to download it.

• Download the Bridge installer for your operating system (Windows, macOS, or Linux)
• Install and then restart your browser for the changes to take effect

If you're using the Trezor Suite desktop app, you don’t need Trezor Bridge.

Step 3: Connect Your Device

Plug your Trezor device into your computer using the USB cable. Ensure:

• The device screen turns on
• You unlock the device using your PIN (if already set)
• You confirm the connection prompt that appears

If the browser doesn’t detect the device, try using a different cable or port.

Step 4: Wait for the Firmware Update Prompt

Once connected, Trezor.io/Start will automatically check if your firmware is outdated.

• If a new update is available, you’ll see a notification: “Firmware Update Available”
• You’ll then be asked to confirm the update both on the website and on the device screen

You must approve this update directly on the Trezor device — this prevents malicious remote updates.

Step 5: Confirm and Install the Update

Carefully follow the prompts:

• Confirm on your device screen that you want to proceed
• Wait while the update downloads and installs (takes about 1–2 minutes)
• Do not disconnect the USB cable or power off your device during this process

During the update, the device may reboot. This is completely normal.

Step 6: Firmware Update Complete

Once the update is complete:

• Your Trezor will display a message like “Firmware updated successfully”
• The browser or Trezor.io/Start will redirect you to continue setup or enter your wallet

At this stage, your wallet and funds are intact. You can proceed to use Trezor Suite for normal operations.

Optional: Verify Firmware Version

To confirm your update:

1. Go to Trezor Suite
2. Open Settings > Device
3. Check the current firmware version listed under device info

This step is recommended if you want to verify that you’re running the latest release.

Troubleshooting Firmware Update Issues

Here are some common issues and how to solve them:

Important Safety Tips

• Never enter your recovery seed online. It’s not needed for firmware updates.
• Always use Trezor.io/Start or Trezor Suite for updates — avoid third-party websites.
• Backup your seed and store it offline before performing any updates, just in case.
• Do not install updates on public or untrusted computers.
