SR-70000HD firmware, version 2.53 build 20899, released 10.09.2019 and archived as a 4.19 MB zip. Neither the flash chip nor the board revision is stated, so inspect the receiver mainboard before use. Such images help recover a receiver that freezes on the logo, reboots repeatedly or lost its software after a failed update, through the USB update menu or an external SPI programmer. Back up the existing memory contents first, and make sure the image is meant for this exact model and fits the chip.
