Yes, your jaboticaba can be revived if, as other growers have stated, its cambium layer is still alive. You will be able to see if you scratch through the surface of the bark and see green beneath. Check an area on the stem a little above the soil line. Do not scratch too much or scratch completely around the tree, you do not want to girdle or otherwise damage it any further. If it is still alive, keep it well watered and do not allow it to dry out. Keep your jaboticaba in a shaded, warm, humid area away from strong sun, high heat, cold, or any other extreme conditions.
Most jaboticabas, or at least the species or varieties most commonly grown by collectors, really like to be wet. They can get root diseases if left standing in water too long, which causes their soil to become anaerobic. But, that condition comes after months of continually standing in water without ever drying out even slightly. Allowing a jaboticaba to completely dry out and stay dry for even a few days leads to a quick death sentence. Jaboticabas seem to be one plant that it is better to over-water than under-water, the opposite of most container plants.
Here is a photograph of a Plinia phitrantha in my collection. Through a bit of neglect coupled with dry conditions in my area, I allowed it to get too dry this spring, about three months ago. It completely defoliated and did not have any leaves for over a month. I kept it watered and placed it in a location where it was shaded from the sun, particularly harsh afternoon sun. It has come back, though not to the level of growth it previously had, at least not yet. It will need a bit of pruning to re-shape it once it is back to full strength. It also has probably been set back a year as to when it will fruit, since all the growth it has done this spring and summer is simply to recover to where it was before I let it get too dry.
