User manual:Updating the Trezor device firmware
Updating the device firmware is often the only way to expand the functionality of your Trezor, to apply new security measures, and to enable newly developed features.
When a new firmware version is released, Trezor Wallet will display an easily noticeable bar in the upper part of the wallet interface.
Clicking the Show details button allows you to review the changes brought with the update and displays instructions asking you to connect the device in bootloader mode.
1. Entering bootloader mode
Connect your Trezor while using your index and middle finger to hold both buttons pressed.
2. Updating the firmware
When in bootloader mode, read the instructions and warnings carefully and check the relevant box to enable the Update my device button. Confirm the update on your device and let the Trezor update the firmware.
After your device loads the new firmware, it will ask you to compare the firmware's fingerprint. Make sure this string of letters and numbers displayed on your device's screen matches what is displayed in your browser and finish the update by confirming this on your device.
Do not hesitate to contact us via Support center if you encounter any unexpected behavior, notifications, or warnings during the update process.
