Update Trezor device firmware
The purpose of this guide is to help you update your Trezor device’s firmware.
Updating the device firmware is necessary to expand the functionality of your Trezor, to apply new security measures, and to enable newly developed features.
Before updating firmware
Before proceeding with any firmware update, make sure your wallet backup (formerly recovery seed) is available and within reach.
If the update malfunctions it could erase the Trezor device memory, so having your wallet backup ready lets you immediately recover your wallet.
You can verify your wallet backup is correct at any time by performing a dry-run recovery:

To proceed with the firmware update, click on Install firmware and follow the on-screen / on-device instructions.
Your Trezor may prompt you that it is restarting in bootloader mode. Select Restart.
On Trezor Model One only: If you are using firmware 1.11.2 or earlier, you must complete two updating steps for bootloader and firmware installation, so the process may require two confirmations depending on the state of the device.
Firmware version will be displayed by the Trezor Device. Confirm you wish to install the update.
Review and confirm any additional prompts from the Trezor Device.
The Trezor will install firmware, and you can track its progress via Trezor Suite.
Your Trezor will be wiped if the device connection is lost while loading the new firmware.
This can sometimes happen due to a faulty or disconnected cable. If this happens, reconnect your Trezor and repeat the installation process and prepare to recover your accounts afterwards.
