Patch laptop BIOS to unlock hidden firmware menus
A Reddit user gave Claude Code a BIOS dump; it disassembled it, found the signature check and patched it, unlocking hidden settings after flashing (secondhand account).
What they did
A Reddit user gave Claude a raw BIOS dump from their laptop and asked it to unlock hidden firmware menus. Claude disassembled the binary, found the RSA signature-check function, and patched the verifier so it always returns true. The owner then flashed the modified firmware themselves. The article says there was no step-by-step prompting.
How it went
After flashing, the owner could reach settings the manufacturer hid. The article is secondhand, relayed from X posts, and gives no laptop model, prompts, or timings.
Worth knowing
Flashing firmware with a disabled signature check carries risk; the source gives no details on backups or recovery, so check those before trying this.
