I have it running now but the only problem I see is that I need it for BCH, not BTC so I wonder if it will work. I tried to put in the new style BCH address but it gave an error. I found the "legacy" address for the BCH address so I used that and it ran. One thing I had to do was add 2 more words to my seed to make the program run. I guess it won't fill in the blanks. lol I'll report back when its finished.
You shouldn't need to add in 2 words... it should detect that your seed is short and add words as required. The only issue is that by default, I think seedrecover may only look for ONE completely incorrect word

Which wallet was your seed from? You might find that the "seedrecover" script will fail to find your correct seed, as it is setup for BTC and ETH... so the derivation path it defaults to is the BIP44 derivation path for BTC which is m/44'/
0'/0'/0... unfortunately, you most likely need to use the derivation path: m/44'/
145'/0'/0 to find your BCH address.

You can try running it using the --bip32-path parameter to force it to the BCH derivation like this:
./seedrecover.py --bip32-path "m/44'/145'/0'/0/"
If you find that it doesn't search for 2 incorrect words, you may or may not also need to add the following argument: --big-typos 2
It will likely generate MILLIONS AND MILLIONS of possible combinations if you use --big-typos 2... as I don't think you can specify where the missing words are. It'll test ALL combinations.
I have another possible solution. It's a custom python script that I hacked together that lets you specify the location of missing words like this:
python find_missing_seed_word.py sketch hockey elbow property symptom peanut genre bubble popular inherit x x
It'll try all the different combinations of valid words, replacing the x's, looking for valid seeds.
It isn't terribly difficult to use, but it doesn't automatically search the output for possible addresses. It just generates 100 addresses for each valid seed that it can find... and you can then search the files looking for a matching address.
When I get some free time I will try out those possible solutions. Thank you! The seed key is from Guarda Wallet for BCH it's a mobile phone Android app wallet.
