I am not very optimistic about the trunk revival either but just holding on to the last straw. I will keep it in the current location where it is shade and a little bit of sun that filters through my patio glass door in the evening. I will keep it there for all of August month and then move it a sunny spot. I believe in this six weeks of time, the trunk (if it is alive) would have formed enough roots needed for tiny amount of foliage it has.
If the leaves do not wilt off, then it is doing photosynthesis and hopefully the sugars will collect over winter to be used in Spring.
