Firmware

From Trezor Wiki
Jump to: navigation, search

In computing, firmware is a computer program that provides the low-level control for the device's specific hardware.

Since Trezor is a simple device, its firmware acts as a complete operating system. Trezor firmware is a key component of the device security and is also responsible for all of its basic and advanced features. To enable future enhancements and security updates, the firmware of the device can be updated when a new version is published using Trezor Wallet or other compatible interfaces with managing capabilities. To prevent malicious updates, only firmware properly signed by SatoshiLabs can be installed without additional user confirmation.

ImportantAll Trezor devices come without firmware installed to ensure that the latest firmware is installed when the device is delivered.

Latest firmware:v2.0.7 (Trezor Model T), v1.6.2 (Trezor One)

Actions: Updating the Trezor device firmware, Factory reset, Wipe device

ImportantFor security reasons, an unsuccessful firmware update (or a successful one using unofficial firmware) will wipe the device from any private information including your recovery seed.
