My node crashed, I’m trying to restore it.
What I have :
- wallet.db (and the password)
- lnd wallet xprv
- channel.backup (many back-ups available)
What I don’t have :
I started a new node, and tried to copy wallet.db and channel.backup into /data/lnd/data/chain/bitcoin/mainnet.
Here are the logs I get :

Does anyone know how to solve this?
I can also use chantools.
Thanks for your help,
