In April 3rd, 2018, I created a bitcoin wallet with Greenbits and sent 0.02 BTC to it (tx)
I wrote down the 24 words in 2 columns in a paper, alternatively in each column. So the 1st one in the 1st, column, the second one in the second column, the 3rd one in the 1st, column, etc. I’m quite sure I didn’t set a password because that option wasn’t given to me with the Greenbits version I used (I installed that one now to see how it was and see if repeating the process would give me some clue)
I had to wipe my phone and reinstall Green. When trying to restore the wallet and entering the words, it says ‘login failed’. The checksum matches, because the OK button turns green.
Some more info. I also wrote down a 3-letter word (‘lns’) on a corner of the paper. Not quite sure what it means. Also, on the back, an alphanumeric 16-character string with numbers and letters, all lowercase. Also, not sure what it means. I’d say it wasn’t written on that day because it’s written in a different color.
Here are all the things I’ve tried, all unsuccessfully so far
- Writing the seed word in another order: first the first column, then the second one. The checksum doesn’t match, so I assume that the right order was the one I described before (I know now that this fancy ordering is probably a bad idea)
- Trying out different letters for the extra 3 words starting with l, n and s – didn’t work as the checksum didn’t match for most of them
I don’t have the nlocktimes.zip file so can’t use garecovery to try to recover my wallet.
AFAIK, Green/Greenbits use a 2 of 2 multisig setup, where Blockstream stores the other key. That would make it hard / impossible to brute force different combinations of the 24 words I have.
What else could I try?
