If you want to search multiple paths, specify those paths in "/btcrecover-1.12.0/derivationpath-lists/BTC.txt" (comment-out the other default paths) or provide multiple paths in --bip32-path arg.
Change this BTC.txt file to something along the lines of this:
m/84'/0'/0'/1
m/84'/0'/1'/0
m/84'/0'/1'/1
m/84'/0'/2'/0
m/84'/0'/2'/1
Keep going with as many additional account numbers as you want, checking the receiving and change paths for each one. Each additional path you add will prolong your search time, however. Then run the same command again, but leave out the
--bip32-path argument. Since you are specifiying
--wallet-type BIP39, btcrecover will check all the paths you specify in the BTC.txt file. You might also want to drop the
--addr-limit to a smaller number to speed things up a bit.
I agree with Loyce though, this sounds like nonsense.
