<p>I'm using <a href="https://github.com/gurnec/btcrecover" rel="nofollow noreferrer">btcrecover</a> 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 <code>3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy</code>. I'm new to blockchain but I believe that this is a Segwit/P2SH account?</p>

<p>Is there a way I can convert this into a P2PKH address so that I can use the tool?</p>

Which software did you create the wallet or address with?

What is it that makes you believe that the seed you wrote down is incorrect? (i.e. missing bitcoin?)

The device erased all private and public keys after 3 unsuccessful attempts to enter a pin and now says the seed is invalid when trying to recover the data

If you haven't sent any bitcoin to the addresses generated from your old seed, consider starting a fresh and generating a new seed.

I'm using [btcrecover](https://github.com/gurnec/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.
