A RAR archive of about 1.22 MB labelled for the Xiaomi Redmi Note 4. It is indexed as firmware, but the name does not say whether it holds a flash image, schematics or other service material, and no board variant is given. Extract it and inspect the contents before use. If it contains firmware, confirm that it matches the exact model variant and back up the existing partitions first. If it turns out to be documentation, it can serve for tracing power rails and locating components during board-level repair.
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 @pepeelectronica. Enginerys does not host this file.
