"Firmware is already installed"

All Trezor devices come without firmware. Make sure you purchased your device directly from our shop and please check the following:

 

  • The USB port of the Trezor Model T should have been covered by a security hologram sticker. For the Trezor Model One, the security hologram is placed on the box.
  • The bootloader verifies the firmware signature. The device only runs if the firmware is correctly signed by SatoshiLabs.
  • Because the recovery seed is generated during Trezor setup, there is no default seed, only the seed you will generate for yourself. 

 

If your newly purchased Trezor device has pre-installed firmware, please contact Trezor support as soon as possible.


If the device came from us and you want to reinstall the firmware, please wipe the device according to the manual:

 


The factory reset will wipe the device, including firmware. You can then proceed with a fresh setup.
 

Make sure you are performing setup only with the official  Trezor Suite.


If you did not purchase the device from us, please contact our support team immediately.
