If you need to take apart your LG420G phone, follow this disassembly guide. This guide will prove helpful in accessing internal components and investigating potential problems your phone may be having.
Before starting, it is important to make sure that the phone is powered down. One thing to note is that some of the components are glued down at points of the disassembly so you may want to use a iOpener to loosen the glue and make the process easier.
It is also important that during the disassembly process, all parts are kept organized and together so that the phone can be reassembled later.
