Hi all,

I’m trying to help a friend recover his BTC and would appreciate advice from experienced users.

In June 2023, my friend purchased Bitcoin via Crypto.com and transferred it to his newly bought Trezor Model T. At the time, he had installed Trezor Suite on his Windows notebook, connected the Trezor, and we saw the BTC appear in the wallet interface. Everything looked fine.

Since then, he hasn’t touched the wallet. He later got rid of his Windows notebook, bought a MacBook, and recently reconnected the same Trezor Model T to the latest version of Trezor Suite on his MacBook.

Now the problem:

    Trezor Suite does not show the amount of bitcoins he transfered in 2023
    Trezor Suite shows a different BTC receiving address than the one used in 2023

    The original address (from the Crypto.com transaction history) still holds the BTC — confirmed via block explorers

    That original address does not appear in the current Trezor Suite session

    He never used any wallet other than Trezor, and no passphrase

    In 2023, the BTC were visible in the Trezor Suite interface

    Now, the BTC are not visible at all in the reconnected Trezor — we don’t see any balance, transactions, or that original address

Additional question:

Does Trezor Suite have the ability to generate receiving addresses and accept BTC without an active connection to a Trezor device?
In other words: Is it technically possible that Trezor Suite generated an address in 2023 that wasn't tied to the connected Model T, and that the BTC were sent to such a standalone address?
Summary of questions:

    Is it possible that the Trezor was reset or re-initialized and now holds a different seed, which is why a different address is being shown?

    Can Trezor Suite show a wallet with a new seed and still appear "valid" without warning the user?

    Is there any way to trace which derivation path or wallet structure generated the original BTC address?

    Are there tools that can help scan derivation paths or compare the seed against known addresses?

    Can that BTC address (where the coins are now) be linked to a known wallet platform, just in case something went wrong during the original send?

    Most importantly: Can Trezor Suite receive BTC independently of a Trezor device, or was the original address 100% tied to the Model T?

    Where are the Bitcoins? Why does the connected Trezor Model T not show the BTC we originally saw in 2023?

We still have the original seed phrase from 2023 stored safely. We're being cautious before attempting recovery, and any advice or guidance would be greatly appreciated.

Thanks in advance!
