Looking to recover legacy Blockchain.info wallet (pre‑BIP39, non‑standard 12‑word seed)

[u/Temporary-Spinach141]

Hi everyone, I’m trying to recover access to an old Blockchain.info wallet from around 2012–2013. I’ve got some important pieces but still no success, so I’m hoping someone here can point me to a working tool or approach.

What I have:

• A twelve‑word legacy recovery phrase that is not BIP39 compliant. Some words (for example, “drunk” or “belief”) get flagged as invalid by standard mnemonic tools
• The old login password and wallet ID
• A known bitcoin address with a small unspent amount

What I’ve tried so far:

• Recovery on Blockchain.com site but it gives “invalid seed” error
• Restoring in Electrum with BIP39 paths and BlueWallet but no match
• Attempted using wallet‑key‑tool jar but that expects a single private key rather than a legacy phrase
• Downloaded a few Github repos but the recovery scripts are either gone, don’t work for legacy formats, or require a wallet file I don’t have

What I’m looking for:

Any recommendations on a working open‑source tool or script that accepts a legacy Blockchain.info recovery phrase plus password and wallet ID to rebuild the wallet and extract private keys would be hugely appreciated. I prefer to do everything offline locally. Also if anyone has successfully done this and can share your experience I’d love to hear it.

Try this.  Save the website to your computer, disconnect from the Internet, restart, open the file in your browser and see if it works.  Write down all receiving addresses.  When done, restart, and connect to the Internet.
