Trezor.io/Start Setup Errors Fixed

How to troubleshoot and fix common Trezor setup problems

1. Trezor Not Detected

Problem:
Your Trezor device is not recognized by Trezor Suite when plugged in.

Solutions:

  • Use the original USB cable that came with your Trezor. Avoid power-only or charging cables.
  • Try plugging the device into a different USB port.
  • If you're using a USB hub, connect the Trezor directly to the computer instead.
  • Make sure your device screen turns on when connected.
  • Restart the Trezor Suite app and reconnect your device.
  • Reboot your computer and try again.

For Windows users:

  • Make sure the Trezor Bridge is installed. Trezor Suite requires it to communicate with the device.
  • Open Device Manager and check if Trezor appears under “Universal Serial Bus devices.”

2. Firmware Not Installed or Update Fails

Problem:
Trezor prompts for firmware installation, but it fails or gets stuck during the update.

Solutions:

  • Disconnect and reconnect your device, then retry the update.
  • Make sure your internet connection is stable.
  • Use a different USB cable or port if the process freezes.
  • Try using another computer if updates continue to fail.
  • If prompted, enter bootloader mode manually:
  • For Model One: Hold both buttons while connecting the device.
  • For Model T: Swipe your finger across the screen while connecting the cable.

3. Trezor Bridge Not Working

Problem:
Trezor Bridge is not detected or fails to work with Trezor Suite.

Solutions:

  • Uninstall any older versions of Trezor Bridge.
  • Download and install the latest version from the official Trezor website.
  • After installation, restart your browser and reconnect your device.
  • Make sure no other crypto apps (like Ledger Live or MetaMask) are running in the background.

4. Stuck on “Waiting for Device”

Problem:
Trezor Suite shows “Waiting for device” and does not continue.

Solutions:

  • Disconnect and reconnect the device.
  • Make sure you have unlocked the device using your PIN.
  • Check for any prompts on the device screen and confirm them.
  • Restart Trezor Suite and try again.

5. PIN Entry Not Appearing

Problem:
Trezor doesn’t ask for a PIN, or the PIN entry window doesn’t show.

Solutions:

  • Make sure the device is securely connected.
  • If using Trezor Model One, check that you are viewing the PIN matrix on your computer screen.
  • On Trezor Model T, enter your PIN directly on the touchscreen.
  • Restart the device and Trezor Suite to trigger the prompt again.

6. Browser Compatibility Issues

Problem:
Your browser doesn’t allow connection with the Trezor device.

Solutions:

  • Use Google Chrome or Firefox, which work best with Trezor Suite and Trezor Bridge.
  • Clear your browser cache and cookies.
  • Disable browser extensions that may interfere, such as privacy blockers or wallet extensions.
  • Try using Trezor Suite desktop app instead of the web version for better stability.

7. Recovery Seed Errors

Problem:
You’re trying to restore a wallet but get errors entering the recovery seed.

Solutions:

  • Make sure the number of words matches your original backup (12, 18, or 24 words).
  • Enter the seed on the device screen (not on your computer) for maximum security.
  • Double-check each word for correct spelling and order.
  • Use only lowercase letters, with no punctuation.

Final Tips

  • Always download Trezor Suite and Trezor Bridge from the official website to avoid scams or malware.
  • Keep your device’s firmware and Trezor Suite updated.
  • Never share your recovery seed with anyone, and never type it into a website or app.
  • If you're ever unsure about a message or error, check the official Trezor support page or contact their support team directly.
