Keep your BitBox firmware up to date to receive the security fixes, bug fixes, and features included in new releases. Firmware is the software running on your BitBox. You update it through the BitBoxApp, without downloading or installing a separate firmware file.

A firmware update does not change your wallet’s recovery information. You do not need to create a new wallet backup or update your existing backup afterward: the backup lets you restore your wallet, while a firmware update maintains the device software.

Before you update the firmware

• Install the latest stable BitBoxApp from the official BitBoxApp download page. If necessary, follow Update the BitBoxApp.
• Use a stable connection and keep the BitBox connected until the BitBoxApp says the firmware update has finished.
• The update does not use your microSD backup. Keep the card stored securely; you do not need to insert, format, or overwrite it.

Updating the BitBoxApp does not automatically update your BitBox firmware. After updating the app, connect and unlock your BitBox to check whether compatible new firmware is available. Follow only the update offered inside the BitBoxApp; do not use a firmware download or update link sent by email, message, letter, or QR code.

Update the BitBox firmware

If the BitBoxApp offers an update for your device, follow these steps. Confirmations take place in both the app and on your BitBox.

1. Open the latest BitBoxApp, connect your BitBox, and unlock it with the device password.
2. Look at Settings in the left sidebar. A red notification dot appears when a firmware update is available.

3. Open Settings, then select Manage device. The tab also shows the red notification dot.

4. Scroll to Device information and select New upgrade available beside the current firmware version.

5. Review the firmware update information in the BitBoxApp and select Upgrade.

6. Read the confirmation shown on your BitBox and use the touch sensors to confirm that you want to update the firmware.

7. Select Upgrade firmware now in the BitBoxApp.

8. Wait while the BitBoxApp and BitBox display the update progress. Do not close the BitBoxApp or disconnect the device.

9. Wait for the BitBox to restart.
10. Unlock the BitBox with its device password. If you use an optional passphrase, enter and verify it only on the BitBox to open the intended wallet.
11. In the BitBoxApp, return to Settings → Manage device → Device information and check the displayed firmware version.

You can now continue using your wallet. The firmware update does not move cryptocurrency, and your existing wallet backup remains valid without being updated or recreated.

If no firmware update is offered

1. Confirm that you installed the latest stable BitBoxApp.
2. Reconnect and unlock the BitBox.
3. Open Settings → Manage device → Device information and check the displayed firmware version.

If no update appears, your BitBox may already have the newest compatible firmware available through that BitBoxApp version. You can compare release information in the BitBoxApp releases and BitBox firmware releases.

If you still expect an update, contact BitBox Support through the official contact form. Include only your operating system, BitBoxApp version, displayed firmware version, BitBox model or edition, and a screenshot of the update area if useful. Do not include wallet secrets or screenshots containing private information.

If the update does not complete

If the connection was interrupted, the update stopped, the BitBox remains on the Bootloader screen, or the same update prompt returns, do not reset the device, restore a wallet, install firmware from another source, or follow third-party recovery instructions.

When the BitBoxApp no longer shows that a firmware installation is in progress, unplug the BitBox and reconnect it. Unlock the device and check whether the firmware update can now complete.

If reconnecting the BitBox does not resolve the issue, record what is shown on the device and in the BitBoxApp, then contact BitBox Support through the official contact form. Include your operating system, BitBoxApp version, BitBox model or edition, any displayed firmware version or error message, the stage at which the update stopped, and what happened after reconnecting. Share no wallet secrets.

Optional: independently verify the firmware

The normal update procedure is complete once you have confirmed the installed version. The following checks are optional.

For release details, see the official firmware releases. Firmware releases are signed, and the BitBox bootloader verifies firmware before accepting and starting it.

Advanced users can also follow How to independently verify the firmware. Firmware hashes depend on the firmware version, BitBox model, and edition, so compare the value shown by your device only with the matching official release value.
