Xiaomi Redmi S2 Y2 (ysl) Schematic

BIOS .7z 10.2 MB Shared

Xiaomi Redmi S2, also sold as Redmi Y2, schematic with device code name ysl, stored as a 10.2 MB 7z archive. Although it is catalogued as firmware, the name clearly indicates circuit diagrams rather than a flash image. Use it to trace PMIC outputs, check the charging path and battery connector, locate test points and follow signals to display and camera connectors when diagnosing a dead or shorted board. Extract with 7-Zip, and confirm the board matches the ysl device before relying on component designators.
