Huawei Y511 archive with an uninformative name that reveals only the phone model. At 16.1 MB the ZIP is fairly large, and could hold schematics, service manual pages, firmware or flashing tools, so inspect it before use. Repair documents for a phone like this are used to trace power rails, locate test points and components, and diagnose charging or no-power faults. Check that the device variant and board markings match the material inside, since Huawei models often have several hardware revisions.
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 @Schematics_Mobile. Enginerys does not host this file.
