How to Update Trezor Firmware Safely
Keep your Trezor secure with firmware updates. Here's how to update safely through Trezor Suite without putting your funds at risk.
Introduction
TL;DR
- Update only through the official Trezor Suite app.
- Confirm your recovery seed is backed up before starting.
- Suite verifies firmware authenticity; confirm prompts on the device.
- Keep the device connected throughout — don't unplug mid-update.
Before you start: back up
Make sure your recovery seed backup exists and is correct. Some firmware updates on certain models can require re-confirming your setup, so a verified backup keeps you safe.
Update through Trezor Suite
Open the official Trezor Suite (desktop is most reliable) with the device connected. When an update is available, follow the prompts; Suite checks that the firmware is authentic before installing.
Confirm on the device and wait
Approve the update on the device and keep it connected until it completes. If it enters bootloader mode, that's normal during firmware work — see Trezor stuck in bootloader mode.
After updating
Reopen Trezor Suite and confirm your accounts appear as expected. The firmware update itself doesn't move or risk your funds, which remain on the blockchain.
