Hello TUMAS,

It could be that your TREZOR is not fully synchronised yet after the firmware update. There is no need to worry if you have the recovery seed and you verified that the coins are in that address via a blockexplorer. Give your hardware wallet some time to see if the coins will be displayed eventually. You can always at a later point restore your wallet by using the seed for recovery.

A few more users have experienced problems after running a firmware update, it seems there is was a bug in the boot-loader that comes with the new firmware patch.
This means would mean that any firmware update may result in a wiped device. In that case you will have to restore your wallet via the recovery seed either way.

If you have any further questions, feel free to send us a DM.

With kind regards,
The Anycoin Direct team
