1. Why Firmware Updates Matter

  • Security Enhancements: Regular updates patch vulnerabilities and strengthen protection against new threats.
  • Improved Compatibility: Updates ensure Trezor works with the latest versions of Trezor Suite, browsers, and blockchain networks.
  • Feature Upgrades: Support for new coins and functions is often added in firmware updates.

2. Firmware Update Workflow via Trezor.io/Start

  1. Connect Your Device:
  • Plug in your Trezor to your computer using the official USB cable.
  • Launch Trezor Suite or follow the prompts on Trezor.io/Start.
  1. Firmware Check:
  • Trezor Suite automatically detects if your firmware is outdated.
  • If needed, you’ll receive a prompt to update.
  1. Download & Verify Update:
  • The firmware package is downloaded directly from official Trezor servers.
  • A cryptographic verification ensures the update is authentic and untampered.
  1. Install the Firmware:
  • Your device enters bootloader mode (you may need to confirm on the device screen).
  • The new firmware is securely flashed onto the device.
  1. Device Restart:
  • Once the installation is complete, your Trezor reboots and is ready to use.
  • You’ll be prompted to reconnect to Trezor Suite.

3. Safety Measures During Firmware Update

  • Recovery Seed Safety: You will never be asked to enter your recovery seed on a computer during an update. If a website or app asks for it, it’s a scam.
  • USB Connection: Do not disconnect your Trezor while the firmware is installing.
  • Official Sources Only: Always initiate updates from Trezor Suite or Trezor.io/Start to avoid malicious firmware.

4. Post-Update Steps

  • Verify the firmware version in Trezor Suite (Settings → Device → Firmware version).
  • Test your wallet connection and accounts to ensure everything functions correctly.
  • Stay informed about new releases by following the official Trezor blog or Suite notifications.

5. Common Firmware Update Issues

  • Device Not Detected? Use another USB cable or port.
  • Update Fails? Restart Trezor Suite, re-enter bootloader mode, and try again.
  • Browser Issues? Switch to Trezor Suite desktop instead of the web version.
