RAR archive of 7.70 MB labelled only with the model code G973F; the name gives no hint of whether it holds schematics, boardview, service manual pages or firmware, so open it to check the contents. For smartphone repair, such packs commonly contain board diagrams used to trace power lines, locate components and test points around a short, and plan component-level work. Confirm the model code printed on the device label or in settings matches G973F exactly, since regional variants differ in board layout and parts.
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 @SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
