Please find more information about this update in our [blog post](http://ledger.com/new-firmware-update-for-ledger-nano-s).\n\n\n**Before you update**\n\n- Uninstall all apps if your device currently has firmware version 1.3.1 or 1.4.2.\n\n- **Linux users** must add new udev rules **before the update**. [Learn more](https://support.ledger.com/hc/en-us/articles/115005165269)\n\n- In some rare cases, your device may be reset during the update. You will then have to restore it from your recovery phrase.\n\n\n**Security enhancements**\n\n- Hardening PIN code entry by randomizing the order of digits and symbols to mitigate a potential attacker from counting button clicks to guess the PIN code.\n\n- Added screen jitter and partial screen inversions so that a potential attacker cannot guess the screen contents through a power consumption analysis. [Learn more](https://donjon.ledger.com/oled-vuln/)\n\nStarting from next firmware updates, the microcontroller (MCU) will be updated by the Secure Element, further increasing the security of the update process and improving the user experience.\n\n\n**Better user experience**\n\n- An entirely new user interface that brings app capacity back to where it was with version 1.4.2. Users will now always press either the left or right button to select an item, and press both buttons simultaneously to validate instead of validating or canceling with either right or left button.\n\n- Significant improvements to the setup and restore procedure including additional instructions and more user-friendly flows. \n\n- Added a Privacy setting that will later replace the Public key export approval setting in Bitcoin-based apps and that enables connections to Samsung Blockchain SDK through a cookie.\n\n- Removed the options to rotate or invert the screen to make the firmware smaller and not to conflict with the new partial screen inversions.\n\n- Fixed a capital S looking more like a number five.\n\n\n**Bug fixes**\n\n- Fixed a bug in WebUSB support on Windows by correcting faulty WinUSB descriptors.\n\n- Fixed a USB bug that reset the device in a few specific configurations.\n\n- Fixed device detection problems on Windows by having a different USB Product ID for each activated interface.\n\n- Fixed the device from timing out when connecting to a browser via U2F.\n\n- Fixed a glitch that rendered text incorrectly in some applications.\n\n\n**Cryptographic improvements**\n\n- Added CTR mode as available block cipher mode.\n\n- Added Stark 256 curve, used for some zero-knowledge proofs.\n\n- Enhanced computation of Schnorr and EdDSA curve points.\n\n- More flexible hmac/hash engine used for key computations.\n\n- Faster execution of the SHA256 hash algorithm.\n\nThank you to all Ledger Beta Testers that helped test the firmware","perso":"perso_11","firmware":"nanos/1.6.0/fw_1.4.2/upgrade_osu_1.6.0","firmware_key":"nanos/1.6.0/fw_1.4.2/upgrade_osu_1.6.0_key","hash":"1DF07429C2761E7B3FB5C2FD342988EEC8120186F26AFDEFF220AD801D7A3AC3","next_se_firmware_final_version":67,"previous_se_firmware_final_versions":[11],"date_creation":"2020-11-19T09:27:49.911944Z","date_last_modified":"2021-04-28T13:45:32.114629Z","device_versions":[6,10],"providers":[9],"minimum_live_common_version":null},{"id":371,"name":"2.2.0-pr1-osu-hidden","description":"","display_name":"","notes":"## WARNING INTERNAL USE ONLY!

You will then have to restore it from your recovery phrase.\n\n\n**A new onboarding flow**\n\n- Simplified the recovery phrase confirmation: choose each word of the recovery phrase among four suggested words. \n- Added screens before the recovery phrase display and after the recovery phrase confirmation to underline the importance of the recovery phrase.\n\n**New features and ETH 2.0 support**\n\n- From the dashboard, hold both buttons for 3 seconds to access device settings. \n- Added new device settings, allowing you to lock your device and uninstall apps directly from your device.\n- Added support for the seed derivation algorithm EIP2333, allowing you to securely sign a deposit contract transaction for Ethereum 2.0 on your device.\n\n**Better user experience**\n\n- Smooth update : no need to disconnect and reconnect the USB cable during firmware updates. Bootloader mode is now automatically launched to update the MCU firmware.\n- Significantly reduced the delay when (un)installing multiple apps in the Manager.\n- A progress bar is displayed on the device screen when installing applications.\n- Added separate settings for the PIN lock and the screensaver.\n- Starting from the next firmware update, the firmware update identifier will no longer be displayed.\n\n**Other changes**\n\n- Fixed functionality to switch between library contexts.","perso":"perso_11","firmware":"nanos/2.0.0/fw_1.6.0/upgrade_osu_2.0.0","firmware_key":"nanos/2.0.0/fw_1.6.0/upgrade_osu_2.0.0_key","hash":"f92229bbe30e5bddcc463e548db46678e972aa946f65ff458decad032f0cf1bc","next_se_firmware_final_version":129,"previous_se_firmware_final_versions":[67],"date_creation":"2021-03-24T10:40:20.617630Z","date_last_modified":"2021-11-29T16:20:26.997387Z","device_versions":[10],"providers":[1,4,7],"minimum_live_common_version":"19.4.0"},{"id":1140,"name":"1.9.0-to-1.10.1","description":null,"display_name":null,"notes":"## Ledger Stax OS version 1.10.1\n\n*Released on 11 May 2026*\n\n**Reminder before you update**\n\n* Ledger strongly recommends that you always keep Ledger OS up to date to benefit from the latest security improvements and features.  \n* Make sure you have updated Ledger Wallet through the notification banner or downloaded [the latest version of Ledger Wallet](https://www.ledger.com/ledger-wallet).\n\n**Blockchain support**\n\n* Added support for Zcash cryptography (ZIP 32\\)  \n* Added support for Aleo cryptography\n\n**Improvements & Fixes**\n\n* Fixed a rare issue restoring a 12-word Secret Recovery Phrase with Ledger Recovery Key  \n* Fixed a bug where the battery charge could be stuck below 100%  \n* Enabled crash logging  \n* Performance and security improvements\n","perso":"perso_11","firmware":"stax/1.10.1/fw_1.9.0/upgrade_osu_1.10.1","firmware_key":"stax/1.10.1/fw_1.9.0/upgrade_osu_1.10.1_key","hash":null,"next_se_firmware_final_version":571,"previous_se_firmware_final_versions":[522],"date_creation":"2026-05-07T09:20:33.923209Z","date_last_modified":"2026-05-11T12:05:59.412383Z","device_versions":[17],"providers":[1,83],"minimum_live_common_version":"27.3.2"},{"id":21,"name":"1.6.0-rc1-osu","description":"","display_name":"","notes":"","perso":"perso_11","firmware":"nanos/1.6.0-rc1/fw_1.5.5/upgrade_osu_1.6.0_cacarc1","firmware_key":"nanos/1.6.0-rc1/fw_1.5.5/upgrade_osu_1.6.0_rc1caca_key","hash":"nononononononohash","next_se_firmware_final_version":37,"previous_se_firmware_final_versions":[24],"date_creation":"2019-04-17T09:00:18.720585Z","date_last_modified":"2021-04-15T09:16:37.623582Z","device_versions":[10],"providers":[],"minimum_live_common_version":null},{"id":1091,"name":"1.9.1-to-1.10.0","description":null,"display_name":null,"notes":"## Ledger Stax OS version 1.10.0\n\n*Released on 22 April 2026*\n\n**Reminder before you update**\n\n* Ledger strongly recommends that you always keep Ledger OS up to date to benefit from the latest security improvements and features.  \n* Make sure you have updated Ledger Wallet through the notification banner or downloaded [the latest version of Ledger Wallet](https://www.ledger.com/ledger-wallet).\n\n**Blockchain support**\n\n* Added support for Zcash cryptography (ZIP 32\\)  \n* Added support for Aleo cryptography\n\n**Improvements & Fixes**\n\n* Fixed a bug where the battery charge could be stuck below 100%  \n* Enabled crash logging  \n* Performance and security improvements\n","perso":"perso_11","firmware":"stax/1.10.0/fw_1.9.1/upgrade_osu_1.10.0","firmware_key":"stax/1.10.0/fw_1.9.1/upgrade_osu_1.10.0_key","hash":null,"next_se_firmware_final_version":559,"previous_se_firmware_final_versions":[535],"date_creation":"2026-04-21T15:37:29.913286Z","date_last_modified":"2026-04-22T13:55:14.522090Z","device_versions":[17],"providers":[1,83],"minimum_live_common_version":"27.3.2"},{"id":656,"name":"1.1.0_to_1.2.0-rc1-osu","description":null,"display_name":null,"notes":"## WARNING INTERNAL USE ONLY!

Please find more information about this update in our [blog post](http://ledger.com/new-firmware-update-for-ledger-nano-s).\r\n\r\n\r\n**Before you update**\r\n\r\n- Uninstall all apps if your device currently has firmware version 1.3.1 or 1.4.2.\r\n\r\n- **Linux users** must add new udev rules **before the update**. [Learn more](https://support.ledger.com/hc/en-us/articles/115005165269)\r\n\r\n- In some rare cases, your device may be reset during the update. You will then have to restore it from your recovery phrase.\r\n\r\n\r\n**Security enhancements**\r\n\r\n- Hardening PIN code entry by randomizing the order of digits and symbols to mitigate a potential attacker from counting button clicks to guess the PIN code.\r\n\r\n- Added screen jitter and partial screen inversions so that a potential attacker cannot guess the screen contents through a power consumption analysis. [Learn more](https://donjon.ledger.com/oled-vuln/)\r\n\r\nStarting from next firmware updates, the microcontroller (MCU) will be updated by the Secure Element, further increasing the security of the update process and improving the user experience.\r\n\r\n\r\n**Better user experience**\r\n\r\n- An entirely new user interface that brings app capacity back to where it was with version 1.4.2. Users will now always press either the left or right button to select an item, and press both buttons simultaneously to validate instead of validating or canceling with either right or left button.\r\n\r\n- Significant improvements to the setup and restore procedure including additional instructions and more user-friendly flows. \r\n\r\n- Added a Privacy setting that will later replace the Public key export approval setting in Bitcoin-based apps and that enables connections to Samsung Blockchain SDK through a cookie.\r\n\r\n- Removed the options to rotate or invert the screen to make the firmware smaller and not to conflict with the new partial screen inversions.\r\n\r\n- Fixed a capital S looking more like a number five.\r\n\r\n\r\n**Bug fixes**\r\n\r\n- Fixed a bug in WebUSB support on Windows by correcting faulty WinUSB descriptors.\r\n\r\n- Fixed a USB bug that reset the device in a few specific configurations.\r\n\r\n- Fixed device detection problems on Windows by having a different USB Product ID for each activated interface.\r\n\r\n- Fixed the device from timing out when connecting to a browser via U2F.\r\n\r\n- Fixed a glitch that rendered text incorrectly in some applications.\r\n\r\n\r\n**Cryptographic improvements**\r\n\r\n- Added CTR mode as available block cipher mode.\r\n\r\n- Added Stark 256 curve, used for some zero-knowledge proofs.\r\n\r\n- Enhanced computation of Schnorr and EdDSA curve points.\r\n\r\n- More flexible hmac/hash engine used for key computations.\r\n\r\n- Faster execution of the SHA256 hash algorithm.\r\n\r\nThank you to all Ledger Beta Testers that helped test the firmware","perso":"perso_11","firmware":"nanos/1.6.0/fw_1.5.5/upgrade_osu_1.6.0","firmware_key":"nanos/1.6.0/fw_1.5.5/upgrade_osu_1.6.0_key","hash":"69922E417220EFCCE5E9A5B12BCB7FCF75DD5590B745A3C123148F1325DE4ECF","next_se_firmware_final_version":67,"previous_se_firmware_final_versions":[24],"date_creation":"2019-10-17T13:53:18.368000Z","date_last_modified":"2020-08-13T10:52:35.799348Z","device_versions":[10],"providers":[],"minimum_live_common_version":null},{"id":547,"name":"1.1.1-osu","description":"","display_name":"","notes":"## Coming Soon: Ledger Recover, provided by Coincover, OS version 1.1.1\n\n*Released January 8th, 2024*\n\n**Reminder before you update**\n\n- Ledger strongly recommends to always keep an up-to-date Operating System version on your Ledger devices, in order to benefit from our gradual security improvements.\n- Make sure you have updated Ledger Live through the notification banner or downloaded [the latest version of Ledger Live](https://www.ledger.com/ledger-live/download).\n\n**News: Ledger Recover, provided by Coincover, Coming Soon on Ledger Nano S Plus**\n\n- We’re excited to announce that this Ledger OS version 1.1.1 enables everyone with a Ledger Nano S Plus to subscribe to Ledger Recover, provided by Coincover, our new wallet recovery solution.\n- Ledger Recover is an optional, paid subscription service which creates a backup for your Secret Recovery Phrase.\n- Updating your Ledger OS will not automatically activate Ledger Recover.
