Some people have problems updating the Trezor firmware which then messes things up.
The advice given is enter your seed phrase to recover your wallet.
Wouldn't this then make the device potentially compromised? the whole point of hardware wallets is the seed never travels across the internet, so once its entered for recovery that is no longer the case, would it then be best to replace the Trezor?
I've never had any issues upgrading firmware on any of my hardware wallets, Trezor One and Trezor T included. Nonetheless, just incase something goes wrong you should make sure you have the seed phrase backed up on a piece of paper before attempting a firmware update.
Should the necessity for restoration arise you'll be prompted to enter the seed phrase on the device, not on the computer.
