Samsung Galaxy S7 boardview in .bvr format, 259 KB. The name gives the model only, with no SM model code, board number or revision, and the S7 was produced with different chipsets by region, so compare the layout against your board carefully. A boardview viewer displays parts placement and net connections, letting you locate components, trace power and signal lines and select test points when chasing shorts or no-boot faults. Check PCB markings first, since an Exynos board and a Snapdragon board would not share the same layout.
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 @GENERAL_SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
