Device not recognized
If your computer or phone does not detect the Trezor® device, try these steps: switch USB cable (use data cable), test a different USB port, restart your host device, and try Trezor Suite on another machine. Avoid USB hubs — connect directly to the host port. Also ensure you’re using an official cable that supports data transfer (some charging cables only provide power).
Firmware update errors
Update failures commonly result from unstable connections or interference. Reconnect the device, close other USB-using apps, and run the update again using the official Trezor Suite. If a firmware restore is needed, follow the official restore instructions — do not attempt third-party firmware unless you are an advanced developer and understand the risks.
Forgot PIN or passphrase concerns
If you forget your device PIN, the device must be reset to factory defaults and then the wallet restored using your recovery seed. If you lose your passphrase (the extra hidden-wallet password), that hidden wallet cannot be recovered without the passphrase. Keep passphrases secure and documented in a way only you can access.
Recovery seed recovery issues
Seed restoration fails most frequently because of typos or incorrect word order. Use the official wordlist and carefully re-enter the exact sequence. If your seed is partially damaged, professional seed recovery services exist — but use only reputable providers and understand the privacy risks.
If the issue suggests hardware tampering or device failure, stop and contact official Trezor® support for guidance rather than using unofficial repair services.
