How can I update my Nano S device?
I'm stuck somewhere in the update, please help!
Please read carefully the step by step instructions as the process require some manipulation (such as pressing the left button while rebooting the device). We have also listed some common issues at the end of this article.
Is it mandatory to update my Nano S device?
The update of your Ledger Nano S to the firmware 1.4.x is strongly recommended, but there is no mechanism to force you to upgrade.
What will happen if I don't update?
We strongly recommend to update but if you don't nothing specific will happen. The Ledger Wallet apps will notify you to update, but you will not get blocked. The device will continue to work normally.
We have published a full disclosure on the patched security issues, so you can have all the details.
What is this update for?
This update brings a lot of new features to improve user experience while increasing the security of the device. For more information on the changes, please refer to the blog post dedicated to the release of firmware 1.4.
Do I have to upgrade my Nano S if I'm not using it?
If you do not have access to your device, or if you do not plan to use it, it is not necessary to upgrade immediately. You'll be able to update when you get access to your device, or if you decide to use it.
What exactly are the security vulnerabilities discovered? Should I be concerned?
Please refer to our full disclosure report on the subject.
Is it possible to downgrade from 1.4 to 1.3.1?
No. For security reasons, it’s not possible to downgrade the firmware of your Nano S.
How many apps can I have on my Nano S with 1.4?
One of the user experience gains of the 1.4 is the possibility to install much more apps on the Nano S. The global limitation is related to the small amount of memory available on the device. The new firmware doesn't expand the memory, but optimizes the size of Bitcoin related apps.
Many cryptocurrency projects are clones of the Bitcoin blockchain and therefore share most of the signature code (such as Bitcoin, Bitcoin Cash, Bitcoin Gold, Litecoin, Dogecoin, Dash, Zcash, Komodo, Stratis, Posw, Pivx, Viacoin, Vertcoin, Stealthcoin, Digibyte, Qtum, Hcash...). By refactoring all common codes in a library (hosted in the Bitcoin app), we were able to significantly lower the size of the other apps. On this principle, it is possible to install up to 18 apps sharing this library.
But if you install apps with a completely different code base (for instance: Bitcoin, Ethereum, Ripple, FIDO U2F, Password Manager) you'll still be limited to 4 or 5 apps.
In conclusion, depending of the type of apps you install, you'll see a very different result. Most probably, you will be in the 10 to 12 apps range.
Tip: when the dashboard has many apps (> 10), the device will freeze for a few seconds just after entering the PIN. This is due to the time necessary to sort the apps to display. A temporary fix would be to remove all apps and install them in the alphabetic order (a future firmware update will address the slowdown).
Why is my device freezing for one or two seconds after entering the PIN?
When you have more than 10 apps, the time to sort the dashboard icons by alphabetic order takes a while. This is a minor (but annoying) issue that will be addressed in the next firmware update.
A temporary fix would be to uninstall all your apps and reinstall them in the alphabetic order (the sort algorithm will be must faster, reducing the lag).
Will I need my 24 words during the update?
No, your seed is not wiped during the process, so you won’t need to input your recovery words. However, make sure your 24 recovery words are properly backed-up and securely stored before starting the update (see: Basic security principles)
Warning: if you have an old version of the firmware (<1.3) then your seed will be wiped and you'll need access to your backup.
Could I lose my funds during this update?
As stated above, your seed is not wiped during the process, so your funds will not be at risk, as long as you carefully follow the guide. However, make sure your 24 recovery words are properly backed-up and securely stored before starting the update (see: Basic security principles)
Is this new version compatible with the Nano, the Unplugged or the HW.1?
No, this update only applies to Ledger Nano S devices.
Is this new version compatible with the Ledger Blue?
No, this update only applies to Ledger Nano S devices.
What if I am stuck on the "Update" message on my Nano S?
If during the upgrading process for some reason your Nano S stay stuck displaying "Update", and the Ledger Manager does not show the message "Installing firmware" but the default page "To begin, connect your Ledger Wallet", then:
- quit and launch again the Ledger Manager
- disconnect your Nano S,
- connect the Nano S again and unlock it by entering your PIN code
The process should start again. Follow the complete guide to update your Nano S here.
If you are on Windows and you are having issues
1. Open device Manager (in control Panel).
2. Find the USB with a yellow warning sign and right click select "Update driver".
3. After the driver is updated, you can close and open Chrome browser, open Ledger Manager, connect your device and just wait.
If you are using Windows 7, you'll have to finalize the update on another computer (not running Windows 7). We are working on a fix, but meanwhile this is the only option.
On other systems (Mac/Linux), if you are having trouble then the only solution is to try again.
The update server processes the request in a queue. The best is to wait when nothing seems to be happening. If it fails, then try again the step. It will eventually update. We thank you for your patience.
Also, if it fails continuously, make sure that no other applications are running on your computer (such as Parity for instance, or a firewall app).
