Replacing ECDSA in Target (arma)

Hello Guys,

i need some help or information what steps i missing . First i must say i'm not a unpacking Professional. I have a Target with Armadillo protected and bruteforced already the cert with Mr.Exodias Akt Tool but i'm trying to replace
the ECDSA Signature.

i have the Base & Replace Code but how to use thie replace code now ??

I can't find either the OEP over x64dbg and Armageddon unpacks it but the binary is not runnable maybe of invalid OEP.

The binary has Debug Blocker no CopyMem..

Any help of Information about unpacking/replacing the signature would be good

Ok Found out how to replace the ECDSA, but the programm wont run even if inline the base code into the target.. without the replace code... does it mean it has additonal protection or are some values wrong ?
