A lot of the planet is molten but not most of it. While there is molten rock and metal in the rest of the Earth only the outer core is all molten. The crust and mantle are mostly solid, and the inner core is solid. The core inner and outer added together, is only about 15 percent of the Earth's volume (the percentage of the mass is larger, but not "most") pubs.usgs.gov In any case even if only one percent of the Earth's volume or mass was solid, it would still take many orders of magnitude more energy than we can release in order to melt the rest. Out best bet to melt the surface is probably to alter the orbit of a very large asteroid (very large, maybe only Ceres would be big enough, I'm not even sure about Ceres unless it hits very fast) to make it hit the Earth, but that's beyond our capability right now.
