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


Keeping your Trezor device up to date is essential for maintaining security, compatibility, and access to the latest wallet features. Whether you're using Trezor Model One or Model T, updating the firmware is easy when you follow the proper process via Trezor.io/Start. Here’s a step-by-step guide for safely updating your Trezor device.

Before You Begin

Make sure you have:

  • Your Trezor device (Model One or Model T)
  • A reliable USB cable
  • A computer with an up-to-date browser or the Trezor Suite desktop app installed
  • Your recovery seed stored safely (you won’t need it for the update, but it’s good practice to have it just in case)

Note: Do not disconnect your device during the update.

Step 1: Go to Trezor.io/Start

  • On your computer, open a browser and type the official setup page address manually.
  • Choose your Trezor model from the screen.
  • Download and open Trezor Suite, if you haven’t already installed it.

Trezor Suite will check for firmware updates automatically when you connect your device.

Step 2: Connect Your Device

  • Plug your Trezor device into the computer using the USB cable.
  • If prompted on the device, confirm the connection.
  • Open Trezor Suite, and it will begin scanning your device.

If a firmware update is available, a notification will appear in the Suite interface.

Step 3: Start the Firmware Update Process

  • Trezor Suite will prompt: “A new firmware is available.”
  • Click Update firmware to begin.
  • Read the warnings and instructions carefully. Trezor will remind you not to disconnect the device and that your wallet will remain intact.

On Model One, you may need to re-enter bootloader mode:

  • Disconnect the device.
  • Hold both buttons while reconnecting the USB cable until the bootloader screen appears.

On Model T, enter bootloader mode by:

  • Holding your finger on the screen as you plug in the device.

Step 4: Confirm on the Device

  • The device screen will ask you to confirm the update.
  • Review the firmware version, then press the button or tap the screen to proceed.

The firmware will begin installing immediately. It usually takes less than a minute.

Step 5: Wait for the Installation to Complete

  • Keep your device connected and do not interrupt the update.
  • Once the update finishes, the device will reboot.
  • You’ll see a confirmation message in Trezor Suite that your device is running the latest firmware.

Step 6: Verify Everything Works

  • After the update, Trezor Suite will reconnect to the device.
  • Your wallet data (balances, accounts, coins) should still be available.
  • No need to re-enter your recovery seed unless the device had been wiped—which is rare and typically avoidable if the update is done properly.

Troubleshooting Tips

  • Device not recognized after update: Unplug and replug it, restart Trezor Suite, or try another USB port.
  • Firmware update fails: Re-enter bootloader mode and repeat the update process.
  • Update wipes device (rare): Restore your wallet using your 12- or 24-word recovery seed during setup.

Why Regular Updates Matter

Firmware updates contain:

  • Security patches for newly discovered vulnerabilities
  • Support for new coins and features
  • Improved performance and bug fixes
  • Interface enhancements and functionality upgrades

By keeping your Trezor device updated, you ensure that your crypto assets remain safe, your tools stay compatible, and your wallet can interact with the latest networks and protocols.

Conclusion

Updating your Trezor via Trezor.io/Start is a straightforward and secure process. With just a few steps, you can ensure your hardware wallet runs the latest firmware and is equipped with all current security measures. Make it a habit to check for updates periodically and always follow the on-screen prompts in Trezor Suite for a smooth experience.
