Flash dump for the TP-Link Archer C20 router, said to cover hardware versions 4 and 4.1 and marked by the source as a fully working image. A full chip dump of this kind is used to recover a bricked router whose bootloader or firmware partition is damaged, by writing it to the SPI flash with a programmer. Check the hardware version on the label under the router, read and keep the original chip contents, and confirm the image size matches the capacity of the flash chip. Note that a full dump may carry another unit's MAC address and calibration data.
