ZIP archive of about 1.94 MB for the Xiaomi Redmi Note 9S, catalogued under firmware, though the name gives no detail about its contents. Given its small size and naming, it may contain schematic or service documents rather than a full flashable ROM, so open it before planning any work. If it holds diagrams, use them for tracing rails and locating components; if it holds firmware, back up the device first and confirm the image matches the exact model and region before flashing.
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 @canalesquematicos. Enginerys does not host this file.
