The user offered a 4 BTC reward to anyone who could assist with recovery.
IndeterminateCase description
A BitcoinTalk forum user (Splashboard) posted in November 2022 that they had forgotten the passphrase to a Trezor hardware wallet and were locked out of their Bitcoin holdings. The user offered a 4 BTC reward to anyone who could assist with recovery. The post illustrated the desperation felt by holders locked out of substantial sums and the lack of any built-in recovery path for hardware wallet passphrases, even for owners with full possession of the seed phrase.

Not enough information is available to determine the outcome.
