Firmware on a hardware wallet controls how the device talks to your computer or phone, how keys are stored inside the secure element, and how the user confirms transactions on-screen. Updates can add new coin support, fix bugs, and patch vulnerabilities. Why update? Because small fixes sometimes block bigger problems later. In my testing, a routine update fixed a connectivity quirk that caused occasional app crashes (so yes, they do matter).
But updates change low-level code. That means you should prepare carefully. Don’t rush in while you’re tired or on public Wi‑Fi.
For a deeper discussion of firmware authenticity and verification, see our detailed guide on firmware updates verification.
Before you run the update, run through this short checklist:
And yes, I double‑check the recovery phrase before any major firmware operation. It’s quick and worth the peace of mind.
| Connection | Reliability | Security | When to use |
|---|---|---|---|
| USB (recommended) | High — fewer dropouts | Highest practical security for updates | Use when possible, especially for firmware installs |
| Bluetooth | Convenient | Slightly higher attack surface; more potential for interference | Use only if USB isn’t available (mobile-only scenarios) |
Note: for firmware installs I prefer USB. Bluetooth is fine for daily balance checks and transactions, but a wired connection reduces variables during an update. And no, Bluetooth isn't automatically insecure — just a different risk profile.

This is a practical, non-exhaustive sequence that matches the typical Ledger Live + Nano X flow. Screen labels can change with app versions, so read prompts carefully.
Launch Ledger Live and connect the device via USB (or pair via mobile Bluetooth). Unlock the device with your PIN.
If Ledger Live shows a firmware update notification, click the update button (often in the Manager or the app banner). If you don't see it, open Manager and follow the prompt.
Follow on-screen prompts in Ledger Live: accept terms and allow Ledger Live to prepare the firmware package. You may be asked to close apps on the device.
On the device you'll be asked to confirm the update. The device will display a fingerprint or version number. Confirm by pressing both buttons (on the same line you see on the device).
Wait. The firmware installs and the device may reboot into a progress screen. Do not unplug or close Ledger Live. This stage typically takes a few minutes.
After reboot, the device may prompt you to enter your PIN again. Reinstall any apps that were removed during the update via Manager and re-open accounts to let Ledger Live re-scan balances.
A few practical notes from my experience: Ledger Live handles signature checks automatically for most updates. Still, follow the device screen: if it asks to confirm a fingerprint or to enter bootloader mode, do it on the hardware wallet itself.
What if the update stops, or the device appears stuck? First, don’t panic. Follow these steps:
But don't enter your seed phrase unless you're restoring on the hardware wallet itself (never into a website or a phone app). That single rule prevents most catastrophic mistakes.
Firmware updates are signed by the vendor and verified by Ledger Live before install. This reduces risks from tampered files. Still, you should:

But don't be overly paranoid either: normal, careful updates are routine and safe when you follow the prompts.

Who should look elsewhere:
Q: Can I recover my crypto if the device breaks?
A: Yes. If you have your seed phrase (recovery phrase), you can restore your accounts on another compatible hardware wallet or supported wallet software. See recover-if-broken.
Q: What happens if the company goes bankrupt?
A: Your crypto is controlled by private keys derived from your seed phrase. As long as you have that seed phrase (and any passphrase), you can restore funds independently of the company. Consider geographic backups and inheritance planning (see inheritance-planning).
Q: Is Bluetooth safe for a hardware wallet?
A: For daily use it's convenient and generally acceptable. For firmware updates I recommend USB because it reduces failure points. See more on connectivity-bluetooth-usb.
Firmware updates keep your hardware wallet functional and secure. They can feel intimidating, but with a few minutes of preparation — confirm your recovery phrase, use a reliable cable, and follow the on-screen prompts — they go smoothly. In my testing, the process is straightforward when you follow the checklist above.
