I have the 34 mnemonic phrase words I wrote down, and the wallet JSON file. Unfortunately I cannot find where I wrote down the password, if I did at all. I did however manage to get what looks like a typical password for me by entering the mnemonic words into blockchain.info. However, this makes me wonder whether the mnemonics were actually for my blockchain.info wallet as I used that to send BTC for the pre-sale. In any case, the password I got does not work for decrypting my ethereum wallet. Tried via GUI client and also with `geth`.
Can anyone advise next steps to unlock this wallet?
