Getting any of the following errors...
Trezor: Recovery failed. Error details: Mnemonic is not valid
Ledger: Invalid recovery phrase
Invalid mnemonic...
Any of the above errors can really ruin your day, especially if you have lost/damanged/reset your hardware wallet. The aim of this tool is to be a 1st (and hopefully only) step required to recover your 24 word seed. It is quick and easy to understand and will work on any system with nothing more than a browser. If you don't have success with this tool, then you can try BTCRecover, (https://github.com/gurnec/btcrecover) though it hasn't been updated in some time.
Enter your 12 or 24 words BIP39 seed phrase. Use the tool OFFLINE for recovery. If one of your words is incorrect, the tool will try to suggest similar, correct words. Try them out. If you are unsure about one of the words, replace it with ? . The tool will calculate all possible words that work. Check them in your wallet or check if any of the calculated addressess is yours. To calculate the checksum (last word - either 12th or 24th), put ? instead of last word. The tool will calculate all correct checksum words - 8 potenial words for 24th and 128 words for 12th.
example: enter a 12 or 24 words seed phrase: "phrase brief ceiling dream rack install fault insane panic surround glory ? library brother hill sauce access child notice picnic dinner panda purity poem"
Note: 12 word seed phrases will take significantly longer to process due to the large number of possibilities for a unknown word.
Enter your seed phrase into the 'BIP39 Phrase' field. If a word is missing or unknown, please type "?" instead and the tool will find all relevant options. If a word is wrong, the tool will try to suggest the closest option.
The tool will suggest all relevant options for the missing word and the derived public addresses for Bitcoin anmd Ethereum. To find out if one of the suggested addresses is actually the right one, you can click on the suggested address tocheck the address' transaction history on a block explorer.

The tool is based on the bip39 project by Ian Coleman https://github.com/iancoleman/bip39 and is a minimally modifed version of the Seed Savior Tool found here: https://github.com/KZen-networks/mnemonic-recovery. Changes involves mostly making the tool responsive to display size and small improvements in UX.
