Full flash dump for the U-vision UV-3316P 16-channel DVR, taken from a 16 MB chip according to the name, supplied as an 11.7 MB RAR. A raw dump like this is written back to the SPI flash with a programmer such as a CH341A when the recorder no longer boots, loops on its logo or has lost its firmware after a failed update. Extract the archive and confirm the image is exactly 16 MB before writing. Read the original chip first and check that the recorder board matches the model.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
