OneKey Classic 1S Pure

Keep Pure connected to USB power throughout use. Reconnect an existing wallet as a hardware wallet; never enter recovery words to reconnect.

Connect an iPhone or Android phone

On a computer, connect Pure by USB and choose Create wallet → Connect hardware wallet in OneKey App; this connects the device without creating new keys. Current app and firmware support Bluetooth on Windows and macOS, but a connected USB data cable takes priority. The browser extension uses USB through WebUSB. Linux Bluetooth remains unconfirmed.

If pairing fails, check Pure’s Bluetooth setting and the app’s phone permissions; Android also needs the documented location permission. Use the official platform-specific troubleshooting for persistent problems.

General is Pure’s multi-asset edition. BTC-Only is supplied with Bitcoin-only firmware.

Changing firmware does not convert or transfer coins. Keep the original network, account and optional passphrase information so you can find those accounts again.

In OneKey App’s Device Management, use the documented Switch to Universal procedure below. Enter recovery words only on Pure, reconnect afterward and check your expected accounts. An app display filter does not change the device firmware.

Create New Wallet generates new keys. Keep Pure powered through USB throughout setup.

To restore existing accounts on an uninitialized Pure, use Import Wallet instead.

• Restore an existing wallet on Pure 

Install OneKey App from its official download before connecting Pure to a computer.

• Find the official OneKey App download 

Check support for the exact asset, network and hardware task first. Non-Bitcoin networks need multi-asset firmware; an app listing alone does not prove support.

BTC-Only restricts this device to Bitcoin.

• Check Pure’s edition before choosing a network 

The receiving QR code shares an address; Pure does not sign by scanning it. For custom Ethereum-compatible networks, Pure may show EVM Address, a chain ID and derivation path. Do not proceed if you cannot establish the intended network.

OneKey App prepares the payment; Pure’s screen and buttons let you review and approve it. Keep USB power attached.

Token spending permissions are different from payments. App warnings and newer firmware parsing do not make every request readable or replace your hardware-screen check.

• What to compare before approving a payment 

Pure can compare your written phrase with its stored phrase without resetting. These steps apply to Classic firmware 3.20.0; keep USB power connected.

A match verifies only the stored phrase. Reopen your funded account with the exact optional passphrase; the phrase check does not verify that access.

• Check the passphrase and hidden-wallet accounts 

A phrase match does not establish replacement-wallet support for your backup, assets or networks. Older firmware menus may differ; do not update just to obtain this check before establishing usable recovery information.

• Check a replacement’s backup, passphrase and asset support 

A passphrase opens separate accounts with your recovery phrase. Keep its exact spelling securely and separately before funding that wallet.

Enable Passphrase in Pure’s Security menu and use OneKey’s documented USB desktop route: select the device in the app → Edit → Add hidden wallet. Enter and confirm the passphrase in OneKey App, then check and confirm it on Pure. The limit is 50 characters from the specified ASCII set; the official guide gives those rules.

From firmware 3.14.0, Pure supports up to three hidden-wallet PIN bindings; the official Bind PIN guide carries the steps. If accounts appear empty, check the same passphrase, network and account. Third-party apps must support passphrases; an empty view does not prove lost funds.

To restore Pure, keep its complete recovery phrase and exact optional passphrase ready. A PIN or app balance cannot replace them; maintain USB power.

For the passphrase step, follow the documented device/app entry route. Restoring keys does not move coins. If accounts are absent, check the passphrase and account selection before creating another wallet or transferring. Without a usable backup or another device that can approve, reinstalling the app cannot recreate the keys.

• Enter the passphrase after restoring 

Stop guessing a forgotten PIN: current firmware resets after five consecutive wrong entries; older guides say ten. A hidden-wallet PIN does not replace the main PIN. Reset only with established recovery information, never to test a backup. Check Recovery Phrase needs its menu and the main PIN. The official reset guide covers old app pairing. Never send words or passphrases to support.

• Check the phrase without resetting 

Have the correct recovery phrase and exact optional passphrase ready before updating. Updating OneKey App and updating Pure’s firmware are separate operations.

Use the non-destructive phrase check if your current firmware offers it and you know the main device PIN.

• Check the phrase before maintenance 

If the firmware update stalls at 90–95% and restarts, use the official computer firmware-website route below. Let the tool detect Pure; do not select files by a similar model name. If that fails too, contact OneKey with the model and error, never recovery words. Do not reset to clear an update error.

A dark screen and a startup error need different checks. Pure has no battery; battery-model charging and storage advice does not apply.

• USB powerCheck the USB power source and cable. If the screen stays dark with power connected, check device detection next.
• Device detected?First connect or pair Pure as a hardware wallet in OneKey App, using computer USB data or phone Bluetooth with USB power. If detected but dark, use support’s route; if undetected, ask for further checks.
• Startup error?Record the exact error and model. The official guide covers its firmware-update route; an app balance does not prove Pure can approve.
