Start with the most common causes before resetting the wallet, restoring from a recovery phrase, or trusting a support message.
USB cable, hub, dock, or port interrupted the update
Trezor Suite or browser update flow is stale or blocked
Device is in bootloader/update mode and needs official recovery instructions
Operating system security, browser permission, or Bridge state interrupted the session
Another wallet app or browser tab is using the Trezor connection
Fake support is exploiting update panic to request seed words
An empty restored view can come from standard wallet versus hidden wallet passphrase, account type, derivation path, selected coin, token view, or Suite sync delay
After Trezor firmware, Suite, Bridge, or browser updates, bootloader/update mode, permission resets, reconnect prompts, and account discovery delays can make the wallet look unavailable temporarily
