Modern files are cryptographically signed with Samsung’s private key. The device’s boot ROM verifies this signature before executing any code. This is part of Samsung’s Secure Boot chain. Attempting to modify or replace sp5001.bin with a custom binary will cause a signature mismatch, and the device will refuse to boot—or in some cases, permanently lock itself. : For a logic-level "paper" on how the
