Router firmware dump for the TP-LINK TL-WR842N, hardware version 4.0, marked as fully working and archived as RAR. Technicians use such an image to recover a unit that no longer boots or accepts a web update, writing it to the SPI flash with a programmer such as a CH341A. Compare the version on the bottom label with the dump, check that the image size equals the chip capacity, and keep a copy of the original flash, because it holds the wireless calibration data and the device MAC.
