Start with the most common causes before resetting the wallet, restoring from a recovery phrase, or trusting a support message.
USB cable, hub, or port interrupted the update session
Wallet app or browser path is stale or blocked
KeepKey is in firmware/update mode and needs official instructions
Operating system security or permission prompt interrupted device access
Another wallet app took control of the device during update
After the update, the app needs a clean reconnect, account refresh, or detection check before balances display
Fake support asks for recovery words during firmware troubleshooting
An empty restored view can come from phrase mismatch, derivation path, account type, selected network, app sync delay, or comparing against the wrong public address
After KeepKey firmware or app updates, update mode, stale desktop or browser sessions, USB reconnects, and account refresh delays can make detection or balances look wrong temporarily
