An 847 KB RAR archive labelled only Alcatel HD1; the name does not say whether it holds a schematic, a service manual or other documentation, nor which handset HD1 refers to. It may be an internal platform or board code, but that cannot be confirmed from the name alone. Extract it with 7-Zip or WinRAR and inspect the contents before use. Match any model or board identifiers found inside against the label and PCB of the device on the bench before relying on them for repair.
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 @esquematicosparatodos. Enginerys does not host this file.
