Service archive for the Samsung Galaxy Grand 2 LTE, model SM-G7105, packed as a 2.60 MB ZIP. The name does not list the contents, but archives of this kind usually hold schematic diagrams or board layout pages used during smartphone board repair. A technician would open the PDFs inside to trace power rails from the PMIC, follow charging and display lines, and find test points around a suspected short. Confirm the model code on the phone label matches SM-G7105 before trusting component references, since regional variants differ.
