This is the first step for any custom ROM.

Because BigDroidOS 201 Patched often disables SELinux enforcement (to allow root apps to work freely), any malicious app you install could easily take full control of the system—deleting partitions, encrypting files for ransom, or hijacking network traffic.

This malware is inserted at the factory level, meaning it cannot be removed by a standard factory reset or by uninstalling applications the normal way because it is embedded directly into the system partition. For privacy-conscious users, replacing the system image with a clean, patched, or entirely different ROM is not just a hobby, but a necessity.
