## Executive Summary This blog post provides a step-by-step tutorial on extracting SPI flash firmware from a Netgear WNDR3700 by using a CH341a programmer (including 1.8V adapter context and a 16-pin chip clip) and the AsProgrammer utility on Windows; it details identifying the MX25L6445E chip, aligning pin 1 markers, connecting the clip to the CH341a ZIF socket, reading and saving the dump, and performing a basic strings search for credentials, while warning that the CH341a supplies power and the router should not be plugged in.
