Firmware dump for a DVR recorder identified as 8286-8AHD-V 01, read from an MX25L128 flash chip, which is a 128 Mbit (16 MB) Macronix SPI memory. The archive is 11 MB, so extract it and confirm the dump is exactly 16 MB before writing. Such images are used to recover security DVRs that boot-loop or are bricked by a failed update. Match the board marking and chip, back up the original with a programmer, and expect settings and passwords to come from the donor image.
