Archive for the Xiaomi Mi 4S phone, 959 KB, stored as RAR. Only the model appears in the name, so the actual contents and document type remain to be confirmed after extraction. Technicians use material of this sort to read circuits, trace rails from the PMIC to the loads, locate parts and test points, and isolate shorts on the mainboard. Note that the Mi 4S is a separate design from the Mi 4 and Mi 4C, so confirm the board markings match before using any values or layouts from it.
