16MB firmware dump for the DS-7208HGHI-K1 recorder board, with the code 80389 and revision 1.4 given in the name, archived as RAR. The model code follows the pattern of Hikvision digital video recorders, but no brand is listed, so check the device label. A dump like this is written to the flash chip with an external programmer to recover a unit stuck in a boot loop or bricked after a bad update. Confirm that rev 1.4 and the chip capacity match, and back up the original contents first.
