The problem with your WIF is that stride collides with checksum and you may have improperly calculated private keys, tomorrow I will launch my calculator to see how to solve it, usually it may be solved by launching several works with a different starting points. Just confirm how many characters you know l, from the gap to the end.
well , it seems like i had no luck in my recovery process because my characters is more than 21 and the searching range is so big ,
is there is any other thing i can do , like lattice attack on my outgoing txns , or something .
i have the public key which computes right to my address , and have everything except for the private key .
Any Help will be appreciated , i am out of luck as you see and hope that i can find something .
also i did not ever shared my wallet with anyone , so no one have it except me ( the owner ) .
