Thanks for your ideas, Alex. Yeah I’m sure that I used the passphrase protected account to access my Daedalus Wallet. Actually, as you already said, it’s most likely that I put in the wrong passphrase or made a mistake writing it down in the first place.
Usually I double check everything before resetting my ledger, in this case I was forced to do it, as after the firmware update I couldn’t access my “secret” account anymore, what I also don’t really understand.
I gonna wait for an answer from ledger support and then try it again.
In worst case, is it possible to pay a recovery company / hacker to fix the wrong digits in my passphrase, any idea? That’s my last hope, as my seed phrase is okay and triple checked.
