Schematic archive for the Motorola Moto G8 Plus, model XT2019, in a 25.0 MB RAR. The documents should map out the main board power distribution, charging circuitry, connector pinouts and links between the SoC and peripherals, which is what you need to trace a missing rail or find the part behind a short. Open with WinRAR or 7-Zip; the sheets typically display in a PDF reader. The XT2019 code covers several regional versions, so check which one your handset is before relying on RF or SIM circuit details.
