Some people have problems updating the Trezor firmware which then messes things up.
I never heard anyone complaining about problems with updating firmware, and if that happens you can always reset and start again.
The advice given is enter your seed phrase to recover your wallet.
This sounds like someone trying to scam you.
Trezor is not going to ask you to enter seed phrase anywhere, but they are giving option of checking if your seed phrase is correct.
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?
No.
