ZIP archive of 44.4 MB for the LG D724, the G3 Beat or G3 S model family. The name gives no list of contents, but its size suggests service manual pages, schematics, layout images or possibly firmware. Extract it with any archive tool and inspect each file before use. Material of this kind helps locate components, trace charging and power rails and follow troubleshooting steps for common faults. Check that the model code on the phone label matches D724, because regional variants of the G3 Beat can use different boards.
