So I kept reading and researching. From what I read, I need the UUID/wallet ID number, from that I can retrieve a copy of the wallet.dat file from the blockchain itself. From there I need at least some of the 12 or 24 word passphrase(?). I found out about btcrecovery.py,may work if I can get enough of the word passphrase.
Not that "
blockchain", based from "
wallet ID" you're talking about the online wallet of blockchain.com/info.
And it isn't Bitcoin's blockchain, they have a "
blockexplorer" service but it's not affiliated with Bitcoin, they just used the name.
If it's the earliest versions of Bitcoin-cli, there's no other way but to recover that wallet.dat or any latest backup of it.
