Title says it all. It's a basic passphrase that I always use (bad practice, I know). The Model T was set up using Shamir shares. Shares are all valid, according to the Trezor. Monero wallet password works fine, but the passphrase gives a different wallet address than the one originally created in the wallet/.keys file.
What's odd is that the second or third time I logged into the wallet, the same passphrase was not accepted when typed on Computer, only when typed on hardware device. And now sure enough, a couple weeks later, it's not being accepted at all. Based on this I am assuming that there is some weird glitch going on and this is not simply forgetting a passphrase.
If it's relevant: I don't recall exactly, but I believe I updated the Trezor firmware after realizing the passphrase wasn't going to work no matter how many times I tried. Also, I am unsure if I added the official Trezor passphrase before or after setting up the Monero wallet. In any case it is the same passphrase and even when I disable it on Trezor suite, the monero wallet is still inaccessible. I have also tried accessing the wallet via CLI, to no avail.
Is there a way to go about recovering the XMR wallet with Shamir shares? I found this--I can make it as far as converting the Shamir shares to a bip39 seed/bip32 root key, but from there..?
