Circuit schematic archive for the Xiaomi Redmi 4A smartphone, compressed as a 2.47 MB zip file and marked Sch in the name. It is indexed as firmware, but the content should be diagrams rather than a flashable image. These drawings are useful when tracing a dead short on the main supply, checking the charging IC, following the backlight and display lines, or locating fuses and coils on a small phone board. Open the extracted pages in a PDF viewer and compare the PCB markings with the document before you rely on component values or measurement points.
