ipro memread 0x0 0x100 Non-zero output means pwned. | Command | Purpose | |---------|---------| | ipro pwndfu | Enter PWNDFU | | ipro pwndfu --exit | Reboot to normal mode | | ipro memread addr size | Dump memory (hex) | | ipro memwrite addr file | Write binary blob to memory | | ipro reset | Hard reset device | | ipro boot x.bin | Boot custom image (requires valid header) | 6. Example: Dump BootROM ipro pwndfu ipro memread 0x0 0x20000 > bootrom.bin 7. Troubleshooting ipro: command not found → Ensure build/ipro is in PATH or run sudo ninja -C build install PWNDFU is not permanent; re-run ipro pwndfu
