Samsung Galaxy J5 service material for model SM-J500H, delivered as a 6.55 MB RAR archive. The file name does not specify whether it contains schematics, layout drawings or a repair manual, so check the contents once extracted. Samsung service packs usually include block diagrams, circuit pages and component placement views useful for diagnosing charging, power-on and display problems and for finding test points. Use 7-Zip or WinRAR to unpack, and make sure the board revision printed in the documents matches the phone on the bench.
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 @Schematic_mobile_iran. Enginerys does not host this file.
