If the device has a USB problem or won't charge, the schematics will identify the Over Voltage Protection (OVP) IC. The diagrams specifically show the path from the USB connector to the charging IC and main battery connector. 2. Dead/Power On Issues
For specific "fixed" solutions where a component is damaged, technicians often use jumper ways instead of a full schematic: Charging Issues:
After testing 20+ files from various GSM forums (GSMHosting, EasyFirmware, Chinaphonefix), we have compiled the characteristics of a schematic.
