Convert P2SH to P2PKH I'm using btcrecover to recover a Ledger BIP39 backup seed that I wrote down but seems to be wrong. The tool only accepts P2PKH addresses and my account was created very recently in this kind of format 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy. I'm new to blockchain but I believe that this is a Segwit/P2SH account?

Is there a way I can convert this into a P2PKH address so that I can use the tool?
Converting address formats is not feasible without knowing the public or private key(s) used to generate them.

Without reviewing the source code of btcrecover, I can't advise whether you should use it or not. But if you do trust it and decide to use it, consider first generating a new seed and address to immediately send your bitcoin to.

Consider any seed you may recover with btcrecover compromised and no longer secure.
