I got locked out of my Ledger Nano S. When setting up the device I was given a 24 words seed passphrase, which I wrote down. The device asked me to verify 3 of the 24 words and my input was valid.
It now turned out that I made a mistake when writing the seed passphrase down since the checksum doesn't validate and I can't recover my wallets. All words that I wrote down are words that are in the BIP32 spec words list.
What strategy would you use (involving coding or not coding) to try and fix the seed passphrase?
