Huawei Honor 7A Pro material in a RAR archive of 865 KB. Only the model name is given, with no board number, revision or content description, so extraction with WinRAR or 7-Zip is needed to see what it holds. If it contains schematics or service pages, it can be used to follow battery and charging circuits, trace display and camera connector signals and locate test points. Check the model code and PCB markings on the phone against the documents, since regional versions may differ slightly.
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 @cyberlanelectonik. Enginerys does not host this file.
