User manual:Updating your Trezor's 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.
The purpose of this guide is to help the user to update the firmware on your Trezor Model T (show for Trezor One).
When a new firmware version is released, the 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 the bootloader modeStart swiping your finger across the Trezor's touchscreen and plug in the USB cable when your finger is halfway through. Once connected in bootloader mode, confirm the connection on your device. You can see the process illustrated in this short clip.
2. Updating the firmware
When in bootloader mode, you can choose to either update the device's firmware or reset the device completely. Read the instructions and warnings carefully and check the respective box to enable the Update my device button. Confirm the update on your device and let the Trezor update the firmware.
Do not hesitate to contact us via Support center if you encounter any unexpected behavior, notifications, or warnings during the update process
