Compact zip archive of 1.10 MB holding a schematic, named only with the model code x6812 and listed under Tecno and Infinix. The name states no device name, board number or revision. Repair technicians use such phone diagrams to follow power rails from the PMIC, check charging and USB lines, and locate the part behind a missing voltage or a short to ground. Confirm the model code printed on the handset or its mainboard matches before trusting component references from these sheets.
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 @phoneSchematics. Enginerys does not host this file.
