Ok, so, I guess a lot of people having same problem as me. So here is my story:
Original wallet(model T):
I used the wallet for more then a year with no problems until recent firmware update.
State before update: having all coins and accounts(1/2/3) visible like Dash/Litecoin, few Ethereum accounts(1/2) with attached ERC-20 tokens to them. See all balances in Suite for web. No pass phrase.
State after update: only first created accounts(1/1) in Dash/LTC with some balance and no additional accounts where coins were places.
Total absence of Ethereum accounts(first one was with zero balance)[only zero balance one] and no possible way to add any other.
New spare wallet from the pack: downloading update, going with recovery: seeds from original wallet, pass phrase left with empty string. Even tried to add hidden wallet like “”.
Result: absolute absence completely of any accounts and coins on the wallet.
Checking original wallet: leftover Dash/Litecoin from (1/1) accounts.
I had my year salary there Trezor team. And always followed security measures that were stated.
Also I have another wallet[3d] with coins, that I didn’t even touch cause of zero information of such situation.
When updating no information about such thing was noticed. Only: keep your seed next to you. The only thing I kept secure and written was my seed. No addresses were written down by me.
I ask for help Crypto-community and Trezor team.
Latter I’ll send tickets(sorry for beforehand panic/fear there).
