Why firmware updates matter
Firmware on a hardware wallet is the code that runs the device’s user interface, cryptographic checks, and the bridge between the secure element and your computer or phone. Updates fix bugs, patch security vulnerabilities, add support for new coins or transaction types, and (sometimes) change the user flow for account management. When a public vulnerability is disclosed, applying the update reduces the time your device is exposed to potential attacks. In my testing, updates often restore compatibility with the latest version of Ledger Live and the blockchains it talks to.

Pre-update checklist — what to do first
Before you press "Update":
- Confirm you have your seed phrase (recovery phrase) securely backed up (seed-phrase). Do the mental check: can you restore to a new device without guessing? If not, pause.
- Make sure you know your PIN.
- Use a trusted computer or phone and a good USB cable.
- Install the Ledger Live latest version (search or visit Ledger Live page on this site). This step matters because Ledger Live performs the signature checks for the firmware.
- Close other wallet-related tools while updating (no MetaMask tabs, no third-party apps).
And: if you use a passphrase (the optional 25th word), make sure you remember it—updates that reset the device will still require the same passphrase to access those accounts (passphrase-25th-word).
How to update firmware — step by step
Important: the exact UI varies by model and the Ledger Live version. Below are safe, general steps. If a prompt asks for your seed phrase during an update, that is abnormal — do not enter it.
Desktop (Ledger Live desktop)
- Install the Ledger Live latest version on your computer (ledger-live).
- Open Ledger Live and connect your hardware wallet with the official cable.
- Unlock the device with your PIN.
- If a firmware update is available you will see a notification or a banner. Click to start.
- Follow prompts from Ledger Live. You will be asked to confirm actions on the device screen (pressing both device buttons is the usual confirmation).
- Ledger Live may uninstall apps on the device before the firmware installs and then reinstall them afterward. That’s normal.
- Wait for the progress bars to complete. Do not unplug.
I noticed that updates can take several minutes when network conditions are slow (downloads and signature checks take time). Be patient.
Mobile (Ledger Live mobile / Bluetooth)
Some models support updates over Bluetooth with the mobile version of Ledger Live. The process is conceptually the same: run the Ledger Live mobile app, connect to the device, and follow the prompts. The firmware image is still cryptographically signed; however, using a trusted device and official app matters more when you rely on wireless transports (connectivity-usb-bluetooth-nfc).
If you prefer additional safety, update on a desktop over USB.

How firmware authenticity is verified
Firmware files are signed by the manufacturer and verified before installation. The device’s secure element and Ledger Live perform attestation checks that confirm the firmware signature matches the manufacturer’s public key (a cryptographic check). If authenticity can't be proven, Ledger Live will block the update and display a warning.
Why that matters: a signed firmware prevents attackers from installing a malicious image that could extract private keys or prompt you for your seed phrase. The check uses public-key cryptography, not a simple checksum.
For manual or advanced verification procedures, see our guide on verify-firmware and the device security pages (secure-element).
Troubleshooting: ledger live not updating
Symptoms can include: no update notification, a stalled download, errors during install, or Ledger Live not launching the update. Try these steps in order:
- Confirm you have the Ledger Live latest version installed.
- Restart Ledger Live and your computer/phone.
- Try a different USB cable and port.
- Disable VPNs and strict firewalls temporarily.
- Run Ledger Live as administrator (Windows) or check macOS permissions.
- If the device appears in a bootloader or recovery state, open Ledger Live and follow the on-screen recovery prompts — do not enter your seed phrase into a computer app unless the recovery process explicitly asks you to restore to the device.
If the app shows an authenticity error, do not proceed with manual workarounds. See troubleshooting-connection and device-damage-recovery.
Risks and common mistakes
- Buying a used device or one from an unofficial seller increases supply-chain risk. Prefer sealed purchases or follow supply-chain-verification steps.
- Never paste your seed phrase or enter it into Ledger Live. Firmware updates never ask for the full seed phrase. If prompted, stop.
- Using unofficial Ledger Live clones or third-party installers can expose you to malware. Download only from official sources.
But remember: even with correct procedures, human errors happen. Use metal backup plates for long-term storage of your seed phrase (metal-backup-plates).
Advanced notes: air-gapped, multisig and passphrases
Air-gapped signing (where a device with no network access signs transactions) reduces attack surface but is more complex to use. For multisig setups, update each participant device and test a small transaction before moving large funds. See multisig and air-gapped guides for workflows.
Passphrase users should be cautious: the passphrase is not part of the seed phrase and is not recoverable by the seed alone. If an update forces a device reset and you lose the passphrase, funds on that passphrase-derived account cannot be restored (passphrase-25th-word).
Advanced users can perform manual firmware verification using attestation public keys and reproducible builds, but that requires cryptographic familiarity and is out of scope for casual users (see verify-firmware).
FAQ
Q: Can I recover my crypto if the device breaks mid-update?
A: Yes — as long as you have the seed phrase (recovery phrase) and the passphrase if you used one. You can restore to another compatible hardware wallet or to a fresh device using the standard restore flow (backup-and-recovery).
Q: What happens if the company stops operating?
A: Your crypto is tied to your seed phrase and keys, not the company. If the vendor disappears you can still restore funds to another compatible hardware wallet or software that supports your derivation paths (plan for this ahead of time — see company-failure-recovery).
Q: Is Bluetooth safe for a hardware wallet?
A: Wireless transports can be safe when the firmware and updates are signed and verified, but they introduce additional attack vectors (pairing, local wireless attacks). For maximum isolation I prefer USB updates on a trusted computer. Your threat model will decide.
Conclusion & next steps
Firmware updates protect both functionality and security. I believe keeping Ledger Live latest version and following the simple pre-update checklist above prevents most update headaches. In my testing, a calm, prepared update process (backup checked, official app, verified cable) is the fastest path to a secure device.
Read the step-by-step Ledger Live guide, confirm your seed phrase backup, and review supply-chain advice at supply-chain-verification. If you want advanced verification details, see verify-firmware.
Stay safe, and update on your schedule — not under pressure.
