Re: Seeking solutions to a 12 year old Electrum wallet mystery

With BTCrecover I am running my seedtoken off an address.db file. When I tried to use the electrum 1.* option, I got the error saying there was a conflict with 'lang' and I have no idea what that means yet.

Oh, that's pertaining to --language arg that you've included to the command.
I've tested it and apparently, selecting "electrum 1.x" will prohibit you from using certain args like --mnemonic-length as well as --tokenlist.
It'll ask about your "best guess" of the mnemonic instead, then proceed to do its programmed 5-phase bruteforce attack to the provided phrase.
(pretty much the same in the old original version of BTCRecover)

I tested BTCRecover v.1.12.0 (seedrecover.py) with an easy seed with 1 wrong word:
v1.x Seed: flutter weak friendship painful shy dirty play forgotten settle double ask season

Code:

./python seedrecover.py --addrs 1MdagXmBnbfGTWjrq2atoK8NY4SqkS5xq6 --addr-limit 10 --dsw --no-eta --no-dupcheck

Best Guess (wrong seed): flutter ask friendship painful shy dirty play forgotten settle double ask season

Code:

--Correct mnemonic seed in the POP-UP--

Yours should be provided with --big-typos 8 arg to limit it to 1 phase with "8" being the number of possible wrong words.
And that's quite a lot of search space and I don't know how to optimize the bruteforce for electrum 1.x seed in seedrecover though.
