Start with the most common causes before resetting the wallet, restoring from a recovery phrase, or trusting a support message.
The device is powered but not passing data to the app
Browser permissions or hardware wallet access prompts were denied
Another wallet app, extension, or tab already controls the device
KeepKey is locked or waiting for an on-device approval
Firmware state or app version is incompatible with the current wallet path
Firmware updated successfully but the app has not refreshed its device permission or account session
Fake KeepKey support page is imitating detection or pairing flow
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
