5) Security, safety, and legal considerations

• Firmware modification can permanently brick devices; always have SPI programmer and recovery plan.
• Modifying firmware may void warranties and violate device vendor policies.
• Replacing modules can introduce vulnerabilities or remove security protections (e.g., bypassing measured boot).
• Do not reuse signed firmware components incorrectly; signature validation may block modified images.
