Flash dump from a TP-Link TD-W8901N ADSL router, hardware version 1.0, noted as the first read taken from the chip. The 2 MB image matches a 16 Mbit SPI flash, which holds the bootloader, firmware and configuration area on such routers. Technicians use a full read like this to unbrick a unit that no longer boots after a failed update. Check the hardware version sticker on the case, back up your own chip, and note that settings and MAC data from the donor unit will be carried over.
