Trezor.io/Start Setup Errors Fixed

If you're facing problems during the initial setup at Trezor.io/Start, you’re not alone. Here’s how to fix the most common setup errors, step by step.

1. Device Not Detected by Browser or Suite

Problem:

• Your computer or browser doesn't recognize the Trezor device.

Fix:

• Ensure the USB cable is working and not a charge-only cable.
• Try a different USB port directly on your computer.
• Avoid USB hubs or docks.
• Use Trezor Suite desktop instead of the web version if Bridge is failing.
• Restart your computer and Trezor device.

2. Trezor Bridge Not Working

Problem:

• Web browser doesn't communicate with your device via Bridge.

Fix:

• Reinstall Trezor Bridge from the official site: https://trezor.io/bridge.
• After installation, restart your browser and computer.
• Make sure Bridge is running in the background.
• Disable conflicting browser extensions (like ad blockers or anti-virus browser add-ons).

3. Firmware Installation Fails

Problem:

• Firmware update or initial installation doesn’t complete.

Fix:

• Try a different browser or install Trezor Suite Desktop instead.
• Use the original USB cable, or try a new one.
• Make sure your internet connection is stable.
• Keep your device connected during the full update process.
• Restart the device and try the installation again.

4. Stuck on “Loading” or Blank Screen

Problem:

• The page hangs indefinitely or shows a white screen.

Fix:

• Clear your browser cache and cookies.
• Try a different browser (Chrome, Firefox, Edge).
• Disable browser extensions.
• Use the Trezor Suite desktop app, which doesn’t rely on browser performance.

5. PIN or Passphrase Not Accepted

Problem:

• The device doesn’t accept your input.

Fix:

• Double-check how the PIN layout changes on your computer screen and your Trezor device.
• If you forget your PIN, you’ll need to reset the device and recover with your seed phrase.
• Make sure Caps Lock isn’t affecting your passphrase input.

6. Can’t Recover Wallet

Problem:

• Seed words not accepted or recovery fails.

Fix:

• Double-check the order and spelling of all recovery words.
• Use the exact same number of words (12, 18, or 24) as when the wallet was created.
• Only enter the words on your Trezor device, not on the computer.
• Use standard English BIP39 word list.

7. Security Warnings or "Unofficial Firmware" Message

Problem:

• Trezor warns you about unverified firmware or device tampering.

Fix:

• Immediately stop setup if you didn’t get the device directly from Trezor.io or an authorized reseller.
• Contact Trezor support.
• Never enter your recovery seed on a device that shows this error.

8. Browser Shows "Blocked by Extension"

Problem:

• Browser or antivirus blocks access to Trezor.io or Bridge.

Fix:

• Temporarily disable:
• Ad blockers
• Antivirus browser shields
• Privacy tools like Privacy Badger or uBlock Origin
• Add trezor.io as an exception in your security settings.

9. Recovery Seed Not Shown

Problem:

• You don’t see a recovery seed or skipped the step.

Fix:

• Factory reset the device through Trezor Suite.
• Restart the setup and create a new wallet to generate your recovery seed.
• Always write it down and store it offline.
