Schematic set for the Xiaomi Redmi Note 4X, internal codename mido, packed in a 9.91 MB ZIP archive. It is filed under firmware, but the name points to circuit diagrams. Repair uses include following voltage rails out of the power management chip, checking battery and charging circuits, and locating components linked to display, camera or audio faults. Extract it and open the sheets in a PDF reader, then confirm that the mainboard revision matches, as the Note 4X uses a different platform from the Note 4 nikel.
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 @esquematicosparatodos. Enginerys does not host this file.
