Archive of service diagrams for the Huawei Y520-U22 smartphone, packed as a 1.71 MB RAR. The name suggests circuit diagrams, likely schematic pages and component layout, though exact contents are not listed. Phone technicians use such sheets to trace charging, power and display lines, locate test points and identify components around the PMIC or charging IC when chasing a short or no-power fault. Extract the archive and confirm the drawings correspond to the U22 variant before relying on part designators.
