Recorder firmware dump for an HVR508 DVR built on the AHD-6108ZY board, packed as a RAR archive of about 11 MB. AHD in the board name points to analogue high-definition camera support. The image is meant for direct programming of the unit's SPI flash when a recorder is bricked, stuck at the logo or refuses software updates. Before use, confirm the board code printed on the PCB matches AHD-6108ZY. Save a copy of the existing chip, and check that the extracted file size equals the flash capacity.
