Trezor.io/Start Setup Errors Fixed

Setting up your Trezor wallet via Trezor.io/Start is normally a smooth process. However, some users may encounter issues during installation, firmware updates, or connection. Below are the most common problems—and exactly how to fix them.

1. Device Not Recognized by Computer

Symptoms:

• Nothing happens when you plug in the device
• Trezor Suite shows “No device connected”

Fixes:

• Use a different USB cable (original cables are recommended)
• Try a different USB port on your computer (avoid USB hubs)
• Restart your computer and reconnect the device
• Try another computer to rule out hardware issues

2. Trezor Suite Can’t Detect Your Device

Symptoms:

• Trezor Suite is open, but stuck on “Looking for devices…”

Fixes:

• Make sure the Trezor device is unlocked using your PIN
• If using the web version, install Trezor Bridge
• Close any other wallet apps that may be blocking access
• Use the desktop version of Trezor Suite instead of the browser

3. Firmware Installation Fails

Symptoms:

• Firmware update gets stuck or crashes
• Device shows a blank screen or “Connect to Trezor Suite” endlessly

Fixes:

• Disconnect and reconnect the Trezor device
• Restart your computer and try the update again
• Make sure you're installing firmware only via Trezor Suite
• If issue persists, enter bootloader mode:
• Model One: Hold both buttons while connecting via USB
• Model T: Swipe your finger while connecting via USB
• Once in bootloader, retry the firmware install

4. Recovery Seed Not Accepted

Symptoms:

• Suite says “Invalid recovery seed” or rejects the entered phrase

Fixes:

• Double-check that you're entering each word in the exact order
• Make sure words are from the BIP-39 word list
• Only enter your seed on the Trezor device screen, never on the computer
• If unsure, start over and carefully retype each word

5. “WebUSB Not Supported” Error

Symptoms:

• Error message when accessing the Trezor web interface
• Device not recognized in Chrome or Firefox

Fixes:

• Use the Trezor Suite desktop app instead of the browser
• Make sure your browser is up to date
• Use Chrome or Firefox—Safari is not supported
• If using the browser version, install Trezor Bridge

6. “Update Required” Message Stuck

Symptoms:

• Suite shows “You must update” but update button does nothing

Fixes:

• Exit and reopen Trezor Suite
• Unplug and replug the Trezor device
• Restart your PC or Mac
• If the problem continues, uninstall and reinstall Trezor Suite

7. Browser Conflicts or Extension Issues

Symptoms:

• Connection issues when using suite.trezor.io/web
• Device detected but actions fail

Fixes:

• Disable conflicting browser extensions (ad blockers, password managers, VPN plugins)
• Open the site in incognito/private mode
• Clear your browser cache
• Use the desktop version to avoid browser limitations

• Never enter your recovery phrase on your computer screen
