If you need help with an old Blockchain.info recovery phrase template, here are some important pointers and troubleshooting steps based on reputable sources:

1. Understand the Type of Wallet and Recovery Phrase

Old Blockchain.info wallets (before their rebranding as Blockchain.com) often used non-standard recovery phrases, not always compatible with modern BIP39 wallets. Recovery phrases could be 12, 18, or 24 words, and sometimes worked differently than newer wallets.

It's crucial to know which format your recovery phrase is in, as misidentifying this can result in failed recovery attempts.

2. Common Issues with Old Recovery Phrases

The phrase might not work with modern wallets if:

The number of words doesn't match typical standards (12, 18, or 24).

The derivation path (the algorithm/path used to turn your phrase into private keys) is not BIP39-compliant, or used Blockchain.info's custom method.

Sometimes, the problem is due to spelling/order errors or using the wrong software for recovery. Always carefully check each word against a BIP39 wordlist and ensure correct order.
