Zip archive of schematic material for the Huawei Mate 20X phone, per the name. Phone service schematics like this usually show the PMIC rails, battery and charging path, display and camera connectors and RF blocks, which helps when tracing a no-power, no-charge or dead-display fault. The name does not state the board version or variant, so check the board markings against the drawings. You may need a PDF reader or a specific viewer for the files inside.
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 @phoneSchematics. Enginerys does not host this file.
