Install Patches — new
Install modified / re-signed / downgraded APKs. A new
Install Patches entry under
Settings → Global Hooks opens one sheet with four patches:
Disable signature verification, Allow downgrade, Disable install verifier (Play Protect scan), and
Allow compressed resources.arsc. They patch Android's package installer inside system_server, so nothing loads into any app — undetectable, and the signature-bypass is applied at the JCA/crypto layer so it covers V1/V2/V3 in one place. Disable signature verification also forces the package manager's checkSignatures result to *always match*, so cross-app signature trust-checks pass (the "signature verification always true" behavior).
FREE; lives under the
System-Server Spoofs master switch (enable it and reboot to arm), with a boot-crash guard. Enabling signature bypass lowers a real security boundary for every install on the device — only install APKs you trust.

Lucky Patcher's signature-verification patches and
PMPatch by vova7878 (whose v7878 engine COPG uses), plus
CorePatch. COPG's implementation is its own.*
