It won't learn about utxos until you go online so i'm guessing that's what you need to do. Take the electrum wallet paired with trezor online.
I went online and it worked. I used Tails, without persistent, I guess it would not compromisse my passphrase.
Thanks for all the help here, guys. If you have more ideas, they will be welcome
