A Reddit user utilized the Claude Code AI assistant to reverse-engineer firmware on an HP 15-dw1036ne laptop, successfully unlocking 55 hidden setup fields and four configuration tabs.

Key Points

• The modification bypassed the RSA-2048 signature verification by patching the firmware routine to return a success signal.
• The process involved using Ghidra for disassembly, UEFITool for extraction, and Unicorn Engine for emulation.
• Claude Code acted as an assistant to bridge documentation gaps, significantly reducing the time required for manual reverse-engineering.
• Successful implementation requires physical access to the motherboard via a hardware flash programmer and carries a risk of bricking the device.
• The unlocked firmware remains model-specific and leaves the laptop more vulnerable to potential future firmware-based security implants.

Why it Matters

This development demonstrates how AI can lower the barrier to entry for complex firmware modification, potentially extending the lifespan of locked hardware that would otherwise become e-waste. While it offers a path for device recovery, it also highlights ongoing security vulnerabilities in hardware lacking robust, root-of-trust boot protection.
