You can't. Otherwise Bitcoin, and ECDSA in general, would be broken.

A private key is retrievable if two different messages are signed using *the same* `r` value and the same private key. Two signatures using different values for `r` are insufficient to recover a private key.

You are asking for help to break one of the core cryptographic assumptions that make Bitcoin work. If what you are trying to do were possible, ECDSA would be considered broken and any form of address-reuse would leak private keys. To the best of my knowledge, neither of these two are currently the case.
