Common Trezor.io/Start Problems & Fixes

Trezor.io/Start is the official setup portal for Trezor hardware wallets. Most users complete the process without issues, but occasionally, technical problems or user errors can cause delays. Here’s how to troubleshoot the most frequent issues.

1. Device Not Detected by Trezor Suite

Problem:

You plugged in your Trezor, but Trezor Suite says “No device connected.”

Fix:

• Try a different USB port or cable (use the original Trezor cable if possible)
• Avoid USB hubs—connect directly to your computer
• Restart both your computer and Trezor Suite
• If using the web version, make sure Trezor Bridge is installed
• Try another browser (Chrome or Firefox are recommended)

2. Firmware Installation Fails or Freezes

Problem:

Trezor Suite gets stuck during firmware installation, or your device displays a blank screen.

Fix:

• Unplug the device, wait a few seconds, and plug it back in
• Restart the setup and don’t disconnect during installation
• If needed, enter bootloader mode:
• Trezor Model One: Hold both buttons while connecting USB
• Trezor Model T: Swipe your finger across the touchscreen while connecting
• Retry the firmware update

3. Trezor Bridge Not Working

Problem:

Trezor Suite (web version) can’t communicate with the device even though Bridge is installed.

Fix:

• Make sure Trezor Bridge is running in the background
• Close other wallet software (Ledger Live, MetaMask) that may block USB access
• Restart your browser and try again
• If problems persist, use the Trezor Suite desktop version, which doesn’t require Bridge

4. “WebUSB Not Supported” Error

Problem:

You see an error message like “WebUSB not supported” when trying to use the web version of Trezor Suite.

Fix:

• Use the desktop version of Trezor Suite for full support
• If staying on browser, switch to Chrome, Brave, or Firefox
• Ensure your browser is up to date
• Disable conflicting browser extensions like VPNs or ad blockers

5. Recovery Seed Not Working

Problem:

Trezor Suite says your recovery phrase is invalid.

Fix:

• Confirm you’re entering all 12, 18, or 24 words in the correct order
• Use only English BIP-39 words from the official word list
• Double-check spelling and avoid typos
• Enter the seed only on the device screen, not the computer

6. Stuck on “Looking for Your Device” Screen

Problem:

Suite keeps scanning but never finds your hardware wallet.

Fix:

• Make sure your device is unlocked with your PIN
• Disconnect and reconnect your Trezor
• Close and reopen Trezor Suite
• Try a different USB cable
• On Linux, ensure udev rules are installed (see trezor.io/start for details)

7. Connectivity Issues on macOS

Problem:

Device not detected or Suite doesn’t load properly on a Mac.

Fix:

• Open System Preferences > Privacy & Security
• Grant Trezor Suite and Trezor Bridge permission to access USB devices
• Use the official Trezor Suite desktop app instead of web version

8. Trezor.io/Start Redirects or Loads Incorrectly

Problem:

The website doesn’t load properly or redirects unexpectedly.

Fix:

• Always enter the full URL:
• Clear browser cache or use private/incognito mode
• Avoid clicking third-party links—always type it directly
